a dirt dobber built a nest on my exhaust cam sprocket and caused the timing belt to jump up and now the engine wont start. with cyl 1 at tdc my flywheel marks line up and the intake cam mark is where it should be, but my exhaust sprocket is 2 notches away from being aliened with my intake sprocket. can i remove the belt and manually turn the exhaust cam to alien with the intake cam without hurting anything else?
