Re: Need help setting timing on a 305

I would also set the engine to tdc on cylinder #1 and check to make sure that the rotor is pointing to number one plug wire on the cap.

Re: Firing order for Distributor Cap/wires

Re: Valve Seal Question

How many feet of rope would I need? 10 feet? I have lots of nylon rope I could use.
Also can I do the intake and exhaust valves at the same time?

Re: Valve Seal Question
