however 21+61+180=262 divided by 2=131-21 =110.
i have checked and rechecked. i cannot get the CL to get on 110.
either one side is asymetrical or i am crazy.
what i don't understand is this. is the cam now advanced 2 degrees [the Jesel belt pulley is on 0], or is it straight up?
my desktop dyno shows most power at 108CL. so i am fine with it being there [that is the CL at 108].
i just want to know where it really is.
thoughts?
thanks

Coul you scan and post the cam card with the the information?
