I'm confounded and don't know what to do at this point. 2 stroke Skyhawk has been running great. Currently has 120 psi of compression. I have the C-clip all the way up on the highest needle jet slot and I'm still getting oily wet plugs after an attempted test start. Just no combustion. No carburetor obstructions. Fresh gas. Proper oil mix. I'm getting good fuel flow into the float bowel. No clogged lines. Proper gas tank ventilation. fuel cap is not obstructed. I checked the main jet for any obstructions, none. Cleaned it out anyway. My Carburetor to intake to engine fit is tight. I am switching spark plugs, no results. I am getting a bright blue spark visible in a well lit garage, so the voltage is there. Cleaned the air filter. It was not dirty but did it anyway. I even took the exhaust completely off to see whether or not it was clogged. It wasn't.
So I have:
-fuel+air+spark+compression, but no combustion. I ordered a second motor and when I get it I will tear into this one if necessary to see what is up with it. The only thing I can think of is that maybe the coil is not sparking enough for combustion even though it looks bright and visible to me.
One clue that might be useful to you but means nothing to me is that yesterday and today while attempting to start it up it would have a single loud "POP". It has never done this before. Not an air escape pop but a combustion pop, but without combustion. So I'm leaning toward Ignition, but not really sure. Any help would be appreciated.
