Ive been racking my brain trying to figure out what is wrong with this thing. I pulled the motor off to check compression and its good. I sealed the backplate and carb. Checked all the fuel lines. New glow plug, fresh fuel. Still the thing wont stay running. I got it to fire a couple times and it would only stay running if i hed the throttle wide open. Ive leaned it out and richened it up. Tried the carb slide in many different positions. Im at a loss, my jato 3.3 runs perfectly. Anyone have any imput or ideas? Btw the ez start batt was fully charged also.
