Question about 1984 Honda VF 750 S
The cam timing is pretty straight forward: with the #1 cylinder at top dead center, the timing marks on the cam sprockets should be level with the valve cover gasket surface.
I can't imagine the engine would run at all if the cam timing were off, my suspicion is that the intake valves on the two forward cylinders are bent (explaining the blow-back through the carburetors). This can occur if the crankshaft is rotated without first having the cam timing set correctly.
