Purchased in 1999 I have had this engine in my Yard Man for 12 years. It has been a great engine I use it on my 5 acres and it has never let me down. My land is not flat but very rugged. I have replaced many blades and belts and have only out of pocket on the engine has been maintance oil changes spark plugs ect. Great Engine. November 21, 2011

This product has design problems Have had BS engines for decades and never thought they would design an engine with aluminum push rods .I can only hope there are not too many other design problems like this one. There also seems to be a problem getting the replacement part as my mower has been down for a month with the excuse of no parts. November 17, 2011

Gas line cracking to close to engine Gas line correction: My 21 hp engine would not start only if I put gas in the carb. Could not find the problem. I took the gas line out from the filter to the carb. Found the gas line was to close to the hot engine causeing it to crack.. Correction--Ran the gas line on the ouside of the engine about 2 inches from engine made of copper line connecting it with rubber hose to filter and carb. The fuel pump does not have the pull power to pull gas into the carb. with any cracks in the rubber gas line. Love this engine works great lots of power. November 2, 2011

Good engine initially, but after two or three years it has issues. I like the engine in my riding mower. However, all at once I lost power and the thing would either go wide open (full throttle) or barely idle. Had to take it to a small engine shop and learned that this type engine has a history of issues with the governor breaking due to poor materials. While the parts are cheap to buy, the engine has to be pulled and dismantled in order to repair it. The whole issue costs a few hundred dollars and the issue occurrs even though the machine has been well serviced. I would gladly recommend this engine without any reservations if it wasn't for the cheap governor which could easily lead to a blown and completely ruined engine. November 1, 2011

bad product with warranty problems used my 27hp 44q777-0136 engine for one cutting and busted a rod!Took it to B&S Certified dealer as requested by B&S.Dealer said it looked as though it may have been machined wrong ,but B&S apparently did not believe the dealer and sent a salesman out(ONE WEEK LATER) to take pictures of engine and send to B&S! Briggs is disputing the Warranty saying it was run low on oil! Now B&S want me to pay for dissassembly and shipping of engine to B&S for further review!If this engine was low on oil,then the full mark is in the wrong place!What a joke! I have e-mailed B&S twice and issue is still not resolved!My next resort will be the Better Business Bureau October 31, 2011

Excellent Engine I have this engine on my Husqvarna MZ6128 Zero Turn mower. I use the mower for much more than just mowing our eleven acres - aerating, detaching, towing a DR road grader. This engine SIPS gas and has never given me trouble in 120 hours of heavy duty use. The Electronic Fuel Management makes for flawless starts no matter the temperature. I could not be happier with this engine. October 31, 2011

Professional series 30 HP I've had the Sears Simplicity Prestige clone (PGT9500) for 6 months now. the engine is reliable, and fault-free. I have only put 20 hours on it so far, but they have been hard-working hours, with a johnny bucket, digging, plowing, and mowing. I'm impressed with the power of this engine, and the quietness of it as well. Very well done! October 31, 2011

2 Yrs without a problem bought this mower with this 24hp engine two years ago. Bought the light weight front end loader accessory as well. Works really well. Lots of power, engine runs great. Need to find a cheaper source for filters. No way a fuel filter should be $10 Sears wants. Air and oil filters too expensive. This is just a matter of finding the right source. October 15, 2011

Professional Series (Single Cylinder)™ 4.7 5 3 3

Good engine 24HP, nice mower craftsman professional The mower and engine perform well, my only problem is with the starting on the engine. Second season, I had Sears fix a hard starting problem which happened to be choke related, minor adjustment and started fine. Two years after same problem has occurred, I bought the manual, but it does not detail the adjustment of the accelerator/choke assembly on this engine. Only separate choke cable and separate accelerator settings. I have contacted Briggs and Stratton with no answer. I have since adjusted it myself, although it starts fine now, I would still like to have the procedure for adjustment detailed by B&S. Again I purchased the manual and this procedure is not defined. I have a very good mechanical background and capable of repairing large and small engines. October 31, 2011

Intek™ with XRD Series (V-Twin) 3.1 5 7 7

Intek V-Twin I have a 18.5hp Intek V-Twin in a Craftsman tractor. I believe it's 11years old now. I have had no problems with this engine, not even any carburetor issues. I use it for mowing and snow removal and I run Mobil 1 in it for easy year round starting. . December 3, 2011

Garbage! I have always been a B & S owner. After this one I will no longer own one. I own a riding tractor with a 24 hp v-twin B & S with 238 hrs of riding time. Last year I replaced a head and push rods due to the valve sleeve unseating. I just purchased the other head and the push rods for the other side along with the gaskets. ($125.) When I contacted Briggs and Stratton via E- mail asking about the problem of the valve guides becoming unseated they as much as told me that it is because my tractors engine is plugged with grass and its causing the motor to overheat! My tractor is clean! When I E-mailed them back the refused to respond back to further questions i had! The problem is that you have an aluminum head with a steel guide and common sense tells you that when heated one tends to expand faster causing the guide to move over a period of time. The valve seat should have a set screw to prevent this from happening. All done with Briggs & Stratton! November 15, 2011

This engine is a lemon I have a 2005 John Deere lawn tractor with a 20 hp v-twin with 110 hrs on it. Last year it suddenly starting smoking so bad you couldn't see. Took it in for repair in April 2011 and the mechanics and Briggs engineers finally determined after several months that an internal plug that cannot be replaced came out (definite factory defect) which causes pressure to build up in the crankcase and be forced up the breather tube into the carb where it is burned. The engine runs fine, but is totally worthless which makes the perfectly good mower worthless. The repair shop and I tried to get Briggs to provide a short block, but they refused to do anything at all. Briggs as a customer friendly company really is at the bottom. November 14, 2011

This product requires a low oil ignition cutoff Great motor, valve adjustments are critical to prevent hard turnover when starting. One major flaw. The motors do not have an ignition shut-off if the oil level drops below the critical level. My 24 hp els motor, which is knbown for sudden oil consumption, blew not one but two rods on a motor that had the oil checked two mowings prior. The oil level had dropped and I have a boat anchor as a result. Honda began installing low oil ignition cutoffs decades ago to help their busy customers who have scores of machines to keep track of and are sometimes used by others. Briggs, time to catch up. Install a switch to save these motors, and your reputation. A replacement will cost me 1000.00. I have been unemployed for 29 of the LAST 36 MONTHS SO PURCHASING THE MOTOR IS NOT POSSIBLE AT THIS TIME FOR ME. Best regards, R Cox November 2, 2011

briggs JUNK I will never buy another briggs product as long as i live!! The 20 HP v-tech with it's untempered parts is JUNK. I have 230 hours on the engine and it dropper the piston rod. I changed the oil and air filter more than reauired by Briggs. After contacting briggs about it. They had a represenative look at it and i was told this happened because i got dirt in the engine. A couple of engineer friends that looked at the ground up parts and said the parts were NOT heat treated. The replacement engine for my mower now has a dual air filter with a snorkel. If this happened to this engine it WILL happen to ALOT MORE engines. It is amazing 230 hours on the engine and it is shot!!! I have babied this engine from day one. If you look in craigs list, you will see LOTS of riding mowers wit NEW briggs engines in them. WHY did so MANY engines go bad if the parts were properly heaqt treated??? Check out the Craftsman, MF and Simplicity mowers with new 20HP engines. Briggs DOES NOT stand behind their products AT ALL!!! No one even offered to replace it with a short block for their cost. If this were a car it would be called a LEMON and the manufacturer would have had to replace it. I am looking at a kawasaki engine to replace the briggs engine. Why bother to buy from someone who does NOT stand behind their product??? Chrysler Retiree October 31, 2011

Does an excellent job for me. This engine runs great,starts easy,easy to change oil,filter & spark plugs.Has 23 hp which gets the job done. October 31, 2011

John Deere L118 Riding Mower In 2005, I purchase a new John Deere L118 Riding Mower with a Briggs & Stratton 22 HP V-Twin engine. It was a great mower but I always had trouble with the engine starting. I replaced spark plugs, starter, etc. but nothing helped. I finely sold the L118 mower in 2011 and replaced with new John Deere L130 with a Briggs & Stratton 22 HP V-Twin engine. This engine starts instantly. Great engine. October 31, 2011

the starter is too small for the engine This engine should have a compression release or a more powerful starter. It is hard to start in good weather. and impossible in the cold. November 5, 2011

Earlier model has head gasket problem I hope that the improvements in the "XRD" system include a redesigned head gasket system. My 6 year old engine (31P777 series) has required a new head gasket twice so far. The gasket fails in the area between the cylinder wall and the oil galley, allowing exhaust to contaminate the oil and oil vapor to be drawn into the cylinder. The original gasket managed to hold up long enough to be out of the two year warranty. I noticed that the latest gasket has a new part number; hopefully it has been redesigned. I have found that older B&S engines seem to run forever with no repairs; my oldest (23 years) is in a push mower. November 2, 2011

My engine came on a Murray Riding Mower I obtained my mower about six years ago. The engine as been running nicely for all that time with one minor problem. The carburetor float was letting fuel fill the cylinder and even the crankcase. First I installed a fuel shutoff in the fuel line. Later I disassembled the carburetor and found the needle valve misaligned with the float, but I replaced the float anyway. The main reason for the downgrade on reliability is due to a muffler problem after I first purchased the mower. It worked fine for a few weeks but then I noticed that the muffler bolts loosened up and the exhaust eventually burned the headlight wiring and melted the front grill and one of the headlight housings. The warranty was not honored. I had to purchase a new muffler which was completely different from the original along with the grill and headlight housing. November 1, 2011

This engine has a problem! Engine wears out intake push rods. Have replaced a total of 5 now when they wear down by rubbing on the glide plate. I have asked B&S if this is normal or a known problem and get a "NO" response with out any info. Have replaced rods, guide and etc and still have the problem. Other than that, the engine is great mower motor. November 1, 2011

Numerous design flaws As a power mechanic I've had the opportunity to repair / rebuild many of these particular model engines. The issues I've seen in this particular engine are, Poor head gasket design. Found many engines blow the head gasket into the valve push rod area over pressurizing the crankcase and causing engine to smoke excessively. Leaky Carbs. Can't count how many times I needed to install new float needle valves also install manual shut-off vales for good measure. Poor cam shaft. Found a few engines that worn the exhaust lobe of the cam shaft in turn not allowing the exhaust valve to open fully. Leaky valve cover gaskets. Valve covers leak, in turn dripping oil onto the muffler and causing engine to smoke. November 1, 2011

Direct replacement engine I had an older 16.5 hp B&S engine on my MTD tractor and needed a replacement engine. This 15.5 hp engine was a direct bolt-on replacement. I don't see any power down difference in this engine by dropping 1 hp. I truly like this engine and will use it until the tractor gives out. October 31, 2011

ROTTEN!! I have owned this for just over 2 years, and it is burning oil!! Just out of warranty, that figures. I contacted Briggs about warranty, no answer. I will never get another Briggs engine in any power equipment...unless I plan to sell it after one year!! October 31, 2011
