It looks to me like you'll have to tear it back down to check the timing marks against the crankshaft sprocket. If they look ok, the problem is the crankshaft pulley hub and you'll need to get a replacement in order to set the timing correctly.

Since it won't start and run, I suspect the belt has jumped a tooth.
