B Series Timing - Crank turns on its own before cams
I'm putting a timing belt on a B18C, I'm doing it by the book - align cam gears with crank mark on oil pump and then install the belt in the correct sequence.
But when I go to put tension on the belt the crank turns on its own slightly (the cam gears don't) so then its all slightly out of alignment.
Why does he crank turns on its own?
To try and fix overcome this, I set the crank mark a few degrees to the right so it's just before TDC and then put the belt on so when tensioned and the crank turns on its own it will eventually line up with the cam gears marks but is still seem to find its own position to as before.
As it sits in this condition the cam gears are 1/2 tooth out each from being lined up when the crank is at TDC. Would piston to valve contact be possible here with this?
It has Brian Crower stage 2 cams and stock B18C pistons.
Thanks,
