Before you get to far with all this I have a Question/s for you. 1) is this a stock cam? 2) have you ever had the dist. Out of the motor.?
If So check and Make sure the #1 piston is top Dead Center Then Take the cap off and MAKE SURE the rotor is at the #1 plug If Not you may very well be 1 tooth off. Is take the dist back out and set it at #1 Then fire it back up and Recheck the timing. Hope this helps }[oooooo]
Ps also double check your valve adjustment It maybe to tight Or too lose.
