Thanks, guys. I was surprised that it is in such good shape. The engine does run badly. So far, I have disassembled and cleaned the carb, which was very clean already,
I ran a compression test (had to use the pull start as the electric start is not engaging) I did not get much compression . . . maybe 25 lbs. I did a cylinder leak test and got only 4% leak, which is good for a 15 year old engine. I think I'll revisit the compression test to see if I get the same results.
Right now, I'm doing an oil change, just because it does not look like it had one recently.
The engine starts fine . . . 1-2 pulls. But it 'studders' quite a bit throughout the throttle range, like its trying to run smoothly, but just can't quite seem to do so.
So, maybe timing ???
Maybe the compression release cam is not disengaging??? I assume that works off of the pull cord ???
The exhaust is clear . . . not sooty.
When I pull the spark plug after running, it is wet, which may indicate a rich mixture.
The carb has no adjustments.
It would be a bummer if I could not get the engine sorted out and had to buy a replacement engine. (there goes the profit margin)
