Okay, so I don't have a 1st gen, but I DO have a 1st gen ignition system, a LA vacuum advance distributor.
Now I've never had to mess with a distributor that I could time before. The guy I got the engine from must have loosened the distributor clamp bolt, so I have no base to adjust timing there.
So I'm just gonna say here what I am gonna try to do to set the dizzy just well enough so I can start the engine to set timing. Correct me if I get anything wrong!
With the dizzy cap removed and spark plugs removed, put my finger on no. 1 cylinder spark plug hole and find compression stroke then crank the engine till it lines up TDC on the timing marks. Here's where I don't know what to do next: Which cylinder should the rotor be pointing to now?
Also, what should I set as far as total timing goes? I tow alot in hot weather, I run 1 range colder spark plugs to avoid knock, and I have to be able to use 87 octane fuel. I'm thinking 15* advance on what base timing?
