Rated 1 out of 5 by from Spark plug keeps fouling When this thing runs it does fine. However, it fouls spark plugs rapidly. First plug lasted about 5 mowings. When the mower wouldn't start I did some research and discovered that others have had trouble with the spark plug. I replaced it and got two good mowings before the problems have started again. I can clean the plug and get it to start but it only runs for a short time before the plug is fouled again. Not sure where the defect is but it is not good.

Rated 1 out of 5 by from Engine failed 5 weeks after warranty Mower died just 5 weeks after warranty ran out even though I changed oil, filter and spark plug frequently. Very upset with engine and mower itself.

Rated 1 out of 5 by from Overengineered garbage I purchased my mower a couple of years ago from Sears. Worked great, until this season, when it refuses to start. After spending countless hours trying to find the problem (cleaning the carburetor, replacing the gas, replacing the spark plug), it seems that the automatic priming mechanism just doesn't want to put fuel into the engine, and it's a mystery as to why.It seems ridiculous to me that I'd have to bring the mower in for service after a couple of years after following all of the maintenance instructions, when my family has had mowers in the past last *decades*. And on those, it's normally rather straightforward to figure out what is wrong with it. I'd take a priming bulb over this any day of the week. Lesson learned, I suppose.

Rated 1 out of 5 by from Terrible I have 5 of these on snapper mowers. They all have the problem of fouling plugs and not starting. I have replaced plugs and even one coil and cleaned the carburetors and still the same issue. Is there a solution to these pieces of junk? The automatic choke is a joke and I cannot understand why old engines are so reliable and these are so terrible.

Rated 1 out of 5 by from New and Won't Start I bought this three days ago and started fine twice. Let sit ten minutes and would not start until about thirty pulls. Now I have to wait two weeks for service dealer to fix the engine. Seems that maybe there should be a recall on this engine, as I have seen a lot of comments about this same problem.

Rated 4 out of 5 by from Excellent if you replace the spark plug Champion RJ2YXLE spark plug that came with it defective out of box, failed completely after two uses. Could not find replacement under this number. Used common J17LM instead (fits hole and sparks OK), runs much better now. Not sure long term, or why B&S chose to use an unavailable part. They need to fix this.

Rated 1 out of 5 by from This mover is a piece of garbage! This mover is a piece of garbage! Had it less than three years on second mover, first would not start after two mows. Why did I buy a craftsman?

Rated 5 out of 5 by from Lawn Mower Performance I have always had Briggs&Stratton engines on everything that has a motor on it from snow blowers to power washers. There has been great improvements with the engines over the years. The latest example is with the lawn mower, it starts on either the first or second pull if even it has been sitting for an extended period of time. I like the feature of automatic choke so there is no guess work to start it. The unit is extremely dependable cuts all levels of grass with no loss in power and stops within 1 to 2 seconds as designed. The only mod I added was an inline shut off so I dont have to worry about old gas sitting in the carb over the winter.
