I changed the plug yesterday, no change.
I do want to take a look at the fuel tank and lines. I'll just replace the lines when I reinstall the tank.

Does it mean anything if it runs well on the ground but not in the air?

Right now it seems good on the ground...?

I do see fuel leaking around the muffler gasket.

I'll follow your instructions. I'll get to the field after work when its not so crowded and I can hear / concentrate.

Inst. call for 2.5 turns out to start. I'll Turn in to lean or out to richen, one way should increase rpm?? How far in or out would be unusual? would 1 full turn be unusual?

I've tried variations with the high speed needle so I'm thinking fuel line or low speed needle???
