I have been checking out several similar posts and it seems I have two problems that could be almost anything, but maybe together they mean something.
First, the motor wants to stall when I put the cover on. Really quickly (10 seconds) it will really lose power. Not a problem if I take off. Nothing pinching. Think I might have an exhaust problem, possibly leaking gasket. I can't tell which one. Tried soapy water without much luck.
Second, it loses rpms in gear. Revs high in a bucket in N, but punks out in gear.
Checked both plugs with a tester and both seemed fine. Compression check showed 42 in one and almost 40 in the other consistently. Seemed low but the threads say that the proximity to each other is most important.
The carb on this model doesn't really have much to adjust.
Again, I know much of this has been covered many times in many posts but I have seen a variety answers that would cause me to rebuild the whole motor. I haven't seen anyone report on both of these problems. Thanks in advance.
