I've opened the HS all the way up to 3 turns - its' better, but still dies at WOT. So sounds to me like it's being starved for fuel. Took the tank apart tonight in case the tank filter klunk was clogged - wasn't, but changed klunk anyway. Also found a kink in the overflow line, got rid of that. But the engine still dies at 1/2 - 2/3 throttle. So next try - carb? Could it be a clogged filter? Any other ideas? Factor needle settings are L 1.1, H 1.5 - can't remember how mine was set up before, but I think I should still be in that ballpark, right?

btw - The engine runs fine at idle (which was where I USED to have problems...)

I'm taking the carb apart tomorrow night - maybe a clogged filter? I'm just frustrated I can't fly this plane tomorrow. Any other possible causes? Could the timing be off, i.e., Hall sensor slightly out of place?

Thanks in advance.
