Re: Piston Arm?
did you put the same thickenss base gasket on as you took off that will affect the timing of the ports but it should still run better than what its doing now?
On some of your pictures of your engine apart I see somekind of black goo inside the engine. I'm wondering now after hearing it run on the video if you have a mainseal leaking on the crank? something is off and thats for sure. Have you checked you rotor on the ignition side to make sure the key isn't sheared?
It make me think that your needle in the carb has worn strangly out of taper but thats anothe hip shot. You do have a problem though
I'm still wondering if you have the one piece flywheels or the bolted ones?
well there some things to think about.
