Title: Lawn mower engine help
Post by: fuzeman on July 26, 2006, 07:55:23 PM: I was fiddling with my Uncle's lawn mower, a Craftsman self propelled push mower. The primer bulb disintegrated and was replaced. Shortly after it stopped running and I think it was junk in the fuel that clogged part of the fuel system near the carb.
I took off the brass screw that held the bowl under the carb and it has a few small holes in it, I assume to let the fuel get sucked up into the actual carb and then mixed with the air. That's where I assume the blockage to be.
I inserted a small metal probe to remove said bloackage and when reassembled it did start and run.
Problem is this. I put enough fuel in it to cut maybe 1/2 our lawn but it ran dry much before that and I am wondering if I opened a 'jet' or fuel nozzle to much with my probing.
Should I just buy another one of the brass things I fiddled with? I didn't see that exact thing listed in the parts listing and the exploded view of it lists the carb as an assembly.

Engine model number is 143 434092 on a Sears Craftsman model #917.378270

Thanks for any help :)

Edit- oops Lawm corrected to Lawn.

Now I can get both my front and back yard mowed with 1.5 tanks of gas and no fouled plugs.

Post by: fuzeman on July 26, 2006, 10:07:27 PM: 1) Carb is not attached directly to the gas tank. Only connection is the fuel line.

2) Pretty sure that's only with tools. I once couldn't get a lug not off so I used a craftsmen tool and bent it. They replaced it NQA.

3) I kind of used 'Uncle's' inappropriately, he passed away in January 2005. You didn't know and it's ok.

4) I figured someone would say this and I have to. It is an old one. But the change was rapid. The previous time it didn't suck gas like a Hummer and the last time it did. Tomorrow is air filter replacement day.

5) I agree, it sure seems like a good mower exxcept the no throttle control thing. That always bugged me.

Thanks for the advice. Mr typetoomuch will keep you informed.
