Rated 1 out of 5 by from Starting issues I bought a chipper with this engine. It is very difficult to start. Once you run it for a while, and turn it off, it is impossible to restart. As per the other review, it is suggested to take it to be serviced at a B & S authorized dealer. It's pretty ridiculous that this machine was brand new 6 months ago, and had done this since day one. Also I am a landscape contractor and have experience with starting all types of equipment, so it isn't user error.

Rated 1 out of 5 by from hot restart This engine powers a wood chipper/shredder. When cold it starts on the first pull, and runs beautifully. However, restart while hot is impossible.

Rated 1 out of 5 by from Engine Cuts out when hot, exhaust fell off, cover fell off I don't usually post to these boards, but this engine has been a big disappointment.Equipment: John Deere 3300psi power washer, 3.2 GPM.The engine starts fine, and then after about 10 minutes of use, it starts to splutter and then it cuts out.I can restart it, it runs fine for a few minutes, then cuts out again.I have done the following:1. replaced spark plug,2. Cleaned carburetor3. Replaced fuel4. Replaced oil with synthetic oil - and i have checked the oil levelSo the fact that it runs fine for a while suggests it is getting fuel and spark OK. It may be getting too hot and then the coil breaks down.. i don't know.Other problems: Way too much vibration. After 2 hours of use, the front plastic cover broke off - i had to re-bolt it on with a big washer.After 1-2 weeks of use, the whole exhaust pipe just broke off. I had to buy a new silencer.I noticed the exhaust pipe gets red hotSo out of frustration, i have decided to replace the engine with a Subaru/Robin 7 hp OHC engine.Sad.. I really wanted to like this thing.Mitch

Rated 1 out of 5 by from Durability IIt is not that new of an engine. It is a 5 horse Briggs on a Mighty Murch wood splitter. It was purchased in the mid 70,s. It was originally used for cmmercial splitting then I got it as a gift. Myself and 3 other people have use it ever since. If I had to guess I would say that it has split 10,000 face cords of wood.Last year I had to put a carb kit in it and the spark plug has been changed 6 times.Other than changing the oil and air filter I also had to resolder the fuel tank 5 years ago.That is all the maintenace that has ben done and it still runs great and is reliable.

Rated 1 out of 5 by from Starting Problems I have had this engine on a chipper/shredder, have used it four times and it has always started on the first pull, but would never restart after refueling until it cooled down for a few hours. Now today, I couldn't get it to start at all even after a new plug was put in. My afternoon was shot and now I have to start taking it apart as the nearest warranty service is over 60 miles. I have and have had lots of Briggs And Stratton engines, and have never had this problem. Very diappointing.

Rated 5 out of 5 by from No Issues at all I bought a Briggs & Stratton 3400 psi 2.8GPM Pressure washer with this engine 3 years ago, Granted I haven't used it on a weekly basis, but when I have, it's been a flawless experience, I only use Alkylate gasoline in it, making sure it's topped off before winter storage, this engine starts every time, usually on the first pull when I use the choke, I never noticed any of the vibration issues others have mentioned. I haven't even had to replace the sparkplug after 3 years of use, the engine seems like a perfect match for this washer, plenty strong, very responsive, when working. The only "issue" I've had is that the retainer for the fuel cap broke off when I opened it for the first time
