Well, the fins were clean. However... I tried to mow again today. It was running great. No smoke, oil drips or anything. It started to heat up a little after 2o minutes of mowing. ANd I started to notice that every time I would change direction form forward to reverse or vise versa, the motor would bobble a little and want to shut down. If I did it very slowly, it would seem to rev back up to where it should and keep on going. I was thinking about all of the things you all have said on here while I was mowing and got to wondering..... Could the fuel pump be going bad? It would explain the motor "bobble" and would probably make the engine run lean as well if it was starved for fuel. It doesn't backfire or smoke like it would i it was getting too much fuel. The carb was just rebuilt. It a lean fuel situation make it heat up this could be causing it. Do you think the same as me or do you guys think it is something else?
