    • Es Goo !
Perfect replacement for Sears Craftsman 22" deck. bolt pattern matched perfect , the holes in the new engine block were not threaded so i just drove the original bolts in it with an impact gun, I bought a throttle control but really didnt need to use it , and it does have a blade brake that hooked up easy without any modding . it sits about 3/16" of an inch above the deck so there's a little air gap but it starts first pull and after a couple times mowing the grass that air gap will disappear. does not come with any oil , just a heads up, but i was up and running in less than an hour, even after i sharpened my blade. ... show more

    • Very short life. I would not buy this motor again.
Initially, the only issue I had with this motor was the mounting bolts were not tapped. I added oil and gas and it ran great. Started first pull. I was delighted. It did spit out some oil even though the dipstick showed the oil level was correct. Tightening the dipstick tube did not help. The next week, I used it and I noticed that it leaked from the carburetor - I'm guessing the float was sticking. Thankfully, I had installed a petcock so I simply shut the gas off when I was finished and this seemed to work - the carb fills at the same rate the engine consumes fuel. Today I was using it again, a mere two weeks after firing it up for the first time and all was well for about an hour. Then the engine only seemed to want to run just above idle. But it was working. I figured I'd check into it after I was finished. However, about a half an hour later, the engine started making some sputtering noises and then shut off. I tried to restart it and the motor feels like it's low on compression. I'm not investing any more time in this, it's going to the scrap yard. I would not buy this motor again. ... show more
