I drove it over and over and it does lack power for what is in it. I am leaning toward the carb being off. But I cant imagine it is cause this much of an issue.
i checked it. 0 on the crank and the cam pin is right a 12 o clock.
did you make sure the chain was tight on the drivers side?? right side as your looking at the engine?
this is very important 2* off can be a big issue.
