Rated 1 out of 5 by from Readstart is a Bad Idea I now have 3 readystart powered tools, 2 lawnmowers and a power washer and I don't know what to do. When they won't start, which is often, there is no way to control the conditions. No choke, no throttle, nothing. I've always favored B&S engines because they started so much better than others. Now their the worst on the market. Monday I am going to talk to a small engine mechanic I know and see if these can be modified by adding a choke and throttle. If not, then I guess I have to get rid of them because my heart can't take the frustration and physical exhaustion of cranking on these engines for an hour just to start them. Oh! and by the way, every sympton on this forum I have experienced. The worst being not able to start them when they are hot.Ken

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 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 Poor Starting Either Hot or Cold I purchased this engine with a Brute 2700 pressure washer. I was initially impressed with it starting in just a couple pulls. It worked well and cleaned great. Then I ran out of gas and needed to start it again. It would not start. I've had two of my children plus myself rotating pulling the cord and have logged over 40 pulls and two blisters trying to get this to start hot. Later, I had the same problem trying to start it cold (it then started fine once hot#. This happens EVERY time I use it. I see this is a common problem noted elsewhere in the reviews. I also noticed the store I purchased it from continues to discount this model well below market price and has posted a sign in front of it noting that once gas is put it they will not take it back. I will take it to a service center, but would like to return this model and spend the extra money for a Honda engine #so much for "Made in USA"). I don't have a good feeling that this will be fixed...never had much luck when such a rampant problem. I hope Briggs & Stratton will reimburse me for the unit or provide lifetime warranty repairs.

Rated 1 out of 5 by from Won't start hot As has been stated elsewhere, it will not start hot. Brand new out of the box. This is a systemic issue apparently.I read the reviews and thought, oh no way it just can't be it's a B&S, they run great forever so long as you maintain them.Started on the first pull.... Ran 25 minutes, and that was it no more work for an hour!!!!It's on it's way back to the store, I'll be buying Honda now.

Rated 1 out of 5 by from Trouble from the get go I have this engine on a Troy-Bilt pressure washer. I have had it for a year and a half. 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 annoying and unacceptable. Now a year and a half later it won't start at all, not fire to the spark plug, this after it was in the shop for 3 months last summer for a non related engine problem. (pump). Forget about the 2 year warranty. The dealer wants so much documentation it's not worth the trouble. Plus I have no intention of having it in the repair shop another 3 months. Enough is enough. If the no fire to the engine can't be fixed cheap by a non warranty repair shop I'll trash it and buy another pressure washer with a more reliable Honda engine. I had a Honda engine on a portable air compressor for over 15 years with no problems, just routine maintenance such as oil changes, air filter changes and spark plug changes. I also have a Snapper self propelled mower with an older B& S engine that has given a lot of trouble. From now on it's Honda small engines for me. I am through with B&S products. I prefer to buy American but when American products are so inferior to products from Asian countries and cost me lots more money to maintain I'll take the Asian products.It will be interesting to see if these true comments get posted or deleted.

Rated 1 out of 5 by from seemed to run fine till it broke a piston or whatever Bought this lawnmower a few years ago but because of a sholuder operation right after I purchased it I couldn't use the lawnmower till last year.Thought it was fine machine although slow moving. Loved the fact that it started so easily1 Used it about 4 times in 2011 and then 2 times in the spring of 2012. When using it in 2012 it suddenly quit. I pulled the spark plug and had oil pouring out. Obviously something broke internally in the engine. The mower and the motor still appear to be brand new but useless. I did not file a warranty claim because of the time period between purchase and failure. However the experience has made me question the reliability of a Briggs & Stratton product.

Rated 3 out of 5 by from A seldom fail part failed. A good engine overall but a little hard to start when hot. This is on a lawnmower. Great power. Problem is it only lasted about 2 years. I cannot find my receipt for an exact date of purchase. The ignition module quit working. No spark. I am looking on-line for a replacement right now. I spent 20 years working on this type equipment and of course it included warranty work on Briggs&Stratton as well as many others. Since I have no proof of purchase date I will not bother with a warranty claim. In all my years dealing with Briggs&Stratton they were top-notch in warranty acceptance, but this time I will pass.
