hi, i recently replaced a head gasket on a 1979 Honda cb750 dohc, after getting all the cams in, new valve shims and the timing correct, i noticed a problem, i can turn the motor over clockwise just fine but when i try to turn it over counter clockwise (witch is the direction it runs in) it turns about half way then stops like its stuck. it will turn over if i force it really hard, but i know somethings wrong. it also puts a lot of tension on the cam chain adjusters even when their loose. i also have no compression too, i dont know if that has anything to do with the problem.
if anybody could help that would be awesome. thanks
