Rated 1 out of 5 by from Poor Performance I bought the weedeater 300 with this engine from walmart to use as a trim mower. The first time I used it, it was great. The second time it hardly ran. I believe the carburator got dirty so I took things apart to clean it, as I've done many times. I put it back together and it still doesn't run. Looking for a carb kit now and finding that is a chore. What a piece of scrap this has turned out to be. I guess it's a live and learn. Don't buy the cheap scrap.

Rated 1 out of 5 by from 2nd mower. This one doing same thing. Bought our first mower from Kmart 550 series. Put oil in, gas in, made sure there was not too much oil just as the book said. Worked great the first time. Went to use it 2 weeks later and could not get it to start to save our lives. My husband changed spark plug and did some other things and nothing.Had to fight with Kmart to return it because they wanted us to find a dealer to fix a brand new mower. We finally got a new one. Same thing, added oil (the oil that came with it) added gas it worked great. 2 weeks later I go out to mow my lawn check oil check gas prime it and nothing. All I get is about a 2 second start and then it dies. I cannot believe this is happening. We do not have the money waste. The las mower I got was at at yard sale and we never even serviced that thing and it still ran for 3 years.We are so frustrated and now stuck with this lawn mower. And now have to find a dealer and get a brand new mower fixed. All the while getting sited from the city for my grass being too long.

Rated 3 out of 5 by from Just ok If I had the decision to make all over again, I believe I'd have gone with a different product. It worked excellent the first season, but has broken down now in the following year. Dipstick is very hard to see and read correctly. Flap on back broke off the fourth (or so) time I used it. It did survive some rough accidents of hitting tree trunks jutting out of the ground, which probably would have caused major trouble on less expensive models. Currently, the engine is totally dead (only second year/season). Won't start, even pulling starter rope. Dies immediately if it does briefly start.

Rated 1 out of 5 by from Total Junk Bought this B&S Series 300 on a Murray lawn mower from Wal Mart, it literally lasted 10 mowings on a 5,000 sq ft lawn, and the engine runs like Junk, it spits and sputters, spews out black smoke, after only 3 months, this engine is total Junk, I thought Briggs and Stratton was one of the best...I will NEVER buy any lawn mower with a Briggs engine, total junk....

Rated 5 out of 5 by from Best Engine you can put on a push mower and here is why. I don't own this engine but I have a family member who does and I have got to use it a few times.I'm going to compare this engine with a Honda GXV160 and tell you why I would pick this engine if I were to buy another commercial push mower.Alright in terms of power, the GXV160, I'd say that is the single most thing I dislike about it, it doesn't have enough. This engine does have the power and I fear it may have too much in the situation where you hit a big root or something. But still the I give the Power point to the Briggs.Terms of reliability, ok lets see here. In terms of starting, both this engine and the honda are an exceeds...I prefer the one or two pulls on the briggs though, to the manual choking on the Honda. But I'd still say its a draw.Now for the big one, Reliability. Both these engines seem to be reliable, both have something I say could be improved. The Briggs starts easy and runs great, so does the Honda. What could be improved on the Briggs, well a stronger crank, maybe a double ball bearing setup like the honda, because it is more powerful so therefore it would be more likely to break if you hit sidewalk or a root. Easy solution, don't use fancy mowers by sidewalks or rooty trees, I still wouldn't do it with a Honda GXV, just use a cheap mower or a weed eater. Ok now what can the "Legendary" honda improve on? Well, the choke system I mentioned earlier. If you get a branch from a small bush or something in the choke system and it bends, then you are going to have fun fixing it or paying 50 bucks an hour to get it fixed. Honda's GXV engine is no good if you can't set it on the right rpm or choke it, and its sad it relies on a small piece of metal attached to a spring that has a guard that doesn't completely cover the mechanism. Sounds like an achilles heal to me. This actually happened to me lol, my "bullet proof" honda commercial mower. In terms of reliability, I will have to give it too the honda, even though it was close...I'd rather fix a bent piece of metal than a bent crank or worse.Performance, well lets see. Briggs, doesn't bog down even in thick wet grass while mulching. Honda, bogs down in wet grass if you haven't mowed for 10 days. Now in reverse, Honda uses less fuel...and is quieter than the briggs which is still a pretty quiet sounding engine.Verdict- I give it to briggs, I'd rather burn a little more gas and not be restarting my mower every 2 minutes when it bogs.Value- the briggs 850 you can get a new engine for under 850 on amazon, the honda is around 400. Terms of whats more for the buck, I say the briggs only because it is cheaper. But too be fair, if you want a fuel efficient very nice sounding engine, the honda is for you. If you want an engine thats gonna get it done in faster in bad conditions you want the briggs 850.Now in conclusion briggs has more points than the honda on my scale. I think it is more of an ideal choice for most conditions. Easier to get parts for, easier to work on than the honda. But by no way am I saying honda is junk it definitely isn't. But if Honda made a 190 gxv it would be a more fair comparison.

Rated 1 out of 5 by from The concept doesn't really make sense This should be a good product on the Brute 22" 3 in 1 self propelled mower. The engine is large and beefy so it would theoretically have plenty of grass cutting power. However there are problems. You have to hold the emergency stop lever (bail control) down so that the engine will stay running. Whoever designed this bail apparently had no consideration for comfort. It hurts your hands after you've been mowing for awhile. This is particularly true because of the way you have to hold the bail while squeezing the drive lever.The side discharge deflector is an extremely cheap piece of plastic that hooks over the hinge for the spring loaded cover that is closed for mulching. I would imagine that the majority of these will get broken after a few seasons. This is even more strange when you consider the excellent quality of the grass catcher. This mower was obviously designed around the rear bagger and they did a good job. However, the side discharge mowing mode seems to be more of an afterthought.However, the worst aspect is the engine. Apparently someone at B&S decided a manual choke or primer bulb was too complicated and came up with the notion of making everything automatic. Now considering that I had no trouble starting B&S engines with manual choke when I was eight years old I don't quite understand the reasoning behind this.Normally you would let the mower idle and then increase to full throttle to mow. However, with the automatic throttle on this product, the engine has no real full throttle setting. Instead it idles slightly fast and then attempts to compensate as you begin cutting and the engine bogs down. In other words, the engine is constantly attempting to reduce throttle and only increases it to stop the engine from dying. This seems somewhat counter-productive with the task of mowing. The auto-choke is also rather baffling. A manual choke works just fine as does a primer bulb. However, this engine uses a somewhat complicated mechanism that holds the choke closed with a spring and then uses an internal wind vane to force the choke open as engine speed picks up. Then it uses a second temperature actuator arm to hold the choke open if the muffler is hot. This somewhat complicated system might be good if it worked but instead it seems to prevent the engine from idling properly.I agree that this mower starts easily. In fact, for an engine of this size it is remarkably easy to start with the pull rope (and a breeze with the electric start). However, it won't stay running. And because of the auto choke and throttle there isn't much the operator can do to compensate. Nor do the B&S engine manuals have any information on getting it to work. I've used many mowers over the years but never one this unreliable. It is possible that something is merely out of adjustment or broken but considering that I would have no trouble tearing this engine down and overhauling it the complete lack of technical information from B&S is aggravating at best. Since the engine is out of warranty I should not have to take it to an authorized repair shop for something that I could do myself. I would imagine that many others feel the same way.Another way of looking at this is that the lack of technical information which would force you to take this unit to a repair shop would somewhat degrade the value since the base price (which seems quite reasonable) would have to be scaled up for potential maintenance.

Rated 1 out of 5 by from Worst money ever spent Brand new. Starts occasionally. Barely runs. Don't accidentally run the blade into any grass or it will die.

Rated 1 out of 5 by from big problems starting I bought a mower with a B&S 450 and the shop had to replace it as it ran for only a few seconds after priming. The next one had exactly the same problem! The next one after that actually started - which was major progress - but seemed sluggish. Now, after a mild winter, it won't start - same problem as the first two. Apparently B&S - even new - can come with significant carburettor diaphragm problems. I'd rather scrap it at this stage than go back to that poor shop again!

Rated 1 out of 5 by from Lousy quality control To start, the so-called "owner's manual" is generic, and ignores the fact that the pictures reverse handle installation for the hardware enclosed. Once past that, I couldn't get the pull rope out more than 8 inches, where it stopped with a metallic "clunk."The problem turned out to be a badly twisted pull cord, but in trying to manipulate the pulley, the rewind spring uncoiled. A full day spent with lousy online material, including a site that doesn't recognize any number or combination of numbers on any label, imprint or stamping on the engine, and repeated offers to buy a repair manual that apparently doesn't exist, I quit. It is going back to the store.I see that the solution offered to the previous irate customer is to spend more time and energy finding a repair shop. Maybe you should consider a bit of quality control instead.

Rated 4 out of 5 by from Powerful Engine I purchased a John Deere JS 46 mower with this engine. It has crazy power for a walk behind mower engine. The oil flter is a nice touch for heavy duty applications. It is quiet for the amount af power it has. My only concern is that it might have a weak shaft in it. After only three uses of the mower it broke without me even hitting anything. I have read reviews on other websites and have seen some of the same problems. Over all I would choose it over the Quantom engines I have owned in the past.

Rated 1 out of 5 by from waste of money the mower worked fine the first two times I used mower the 3rd time I used it would run for 5 seconds and die. i would prime the mower it would run 5 seconds die. that what I expect out of a 3 year old mower not 3 month old mower.

Rated 1 out of 5 by from very poor design easy start, runs great - UNTIL - I push mow around and under trees and bushes, which cause the gas and oil cap to come loose, sometimes causing fluids to spew all over the engine and deck. this last time the entire oil dipstick was pulled from the engine. Engineers, you are welcome to my place for hands on testing, research & development...

Rated 5 out of 5 by from staring the best and built the best. I bought the engine from my neighbor in may of 2011. He bought it from sear about 2 years ago. the mower sat for about 2 year after the doc. said you need to stop mowing. The engine has a starter that i never use. I mow grass for my business. I do not prime of choke the engine. I just pull the cord one time and the engine firers. Two months after i bought the push mower i hit a stomp and bent the crankshaft but did not break the flywheel key. the engine was quite easy to tare down and rebuild with a new crankshaft.

Rated 5 out of 5 by from Great engine I have this engine on a Craftsman 2700 PSI pressure washer. I bought it in 2010 and have used it allot since then. The engine must have about 70 hours on it total. I use it for cleaning my walkways, drive way and my siding. My house gets very bad algae growth all over the back deck, patio and back portion of the house. It takes me about two days to clean everything off. In that time I probably go through about 6 tanks of fuel. (I used to have a cleaning company do the work but they always managed to damage the brick work on my patio). This engine has never given me any trouble what so ever. Mine is sometimes hard to start when its hot but its not all the time. As it gotten more hours on it, its actually become less and less of a problem. I only run 89 octane in all my small 4 cycle engines. I find that 89 octane seems to run cleaner. Since I've started using 89 octane I've noticed the spark plugs on my engines don't have as much carbon build up on them. With all my small 4 cycle engines I change the oil, spark plug and air filter at the start of the season. I also use fuel stabilizer to prevent the gas from going bad. I know how much ethanol fuel likes to absorb water and ruin rubber and aluminum parts. So if I had the choice I'd buy another pressure washer with this engine again. For me it runs great.

Rated 2 out of 5 by from automatic choke *ez start* Bought this mower 120 days ago, so I am not even able to return it to the store (has a 90 day return policy) I bought it from. The ez automatic choke start keeps flooding the engine so that it won't start. Did all of the trouble shooting recommended in the manual, to no avail.Will say that when it did start it mowed fine. I would NOT recommend this mower to anyone. For the price that I paid, I should have a mower that starts easily and reliably for more than 120 days. Garbage, very disappointed with B&S.

Rated 1 out of 5 by from Worst Lawnmover I have ever owned! This is the second Briggs and Stratton mower that has failed on me this season! I returned the first one and demanded a new mower. The second purchase was a Snapper with the same B & G engine. The Snapper started for a minute then sputtered and would not restart. I was told that the parts are not available locally and i have to order on line. I keep having to pull my fifteen year old Toro out of the shed with last years gas to cut the lawn to get the job done! My Toro is so old it is held together with clothes pins. However it still starts on the first pull and gets the job done. I have been a lifelong supporter of KMART and SEARS but that has know changed.

Rated 5 out of 5 by from Excellent I am a technecian and really favor this series. I have worked on Briggs & Stratton engines for the last 15 years or so and much favor and recommend this series.

Rated 1 out of 5 by from Will not start hot As the guy said in previous review, I have this engine on a Troy-Bilt pressure washer. I have had it for two years. From the first day once the pressure washer has been used and the engine is turned off, to fuel , take a rest or whatever, it will not re start until it has completely cooled off to air temperature. This is unacceptable. You can pull till you have a heart attack and its not going to start till its cold again. I have a electric pressure washer I use if the job is going to require turning off the engine for any reason. Love to know why it will not start hot. Found many similar complaints on the Internet about B&S motors with Ready-Start.

Rated 1 out of 5 by from Just doesn't cut it. The lawn, that is. We bought this mower last summer and had a lot of trouble starting it. It would roar to life, but then die after one or two seconds. Eventually, by wedging an object between the throttle cable and the push handle to pull the cable tighter we got it to start, but it ran very roughly. This year it won't start at all, with the same symptoms of coming quickly to life and then stopping almost immediately. I gather from the other comments that I'm not alone. All my other experiences with Briggs and Stratton engines have been positive, so I'm quite angry that we seem to have purchased a lemon.P.S. Your system won't accept our model number either, so I can't download a manual. 9S502-0520-B1
