Yes I can turn the motor by hand, if I bump start it car runs great, would a weak starter have trouble turning a higher compression motor? I have Ross 10:1 compression pistons, the only other thing is the pivot play on the starter if it were 2 mm high it might be skipping on the flywheel, going to play with it tomorrow and see if I can get it working without the noise. I have another 2g here so goin to try the starters in there to be sue that work
