I have checked the gears and the distributor at least a dozen times now, I have brought it up to top dead center on number one, checked the rotor for location, I have pulled the timing cover and checked my marks to make sure I didn't get something out of line there, checked for spark, made sure it had good fresh fuel. I am sure it is probably something simple I am over looking but for the life of me can't figure out what that would be. I had a friend of mine that went through the same thing I am and he never did get his to start when he set it for advance, just wonder if this cam will not allow me to go that far advance. the package from cloyes states that it is 4 degrees advance.
