Performance timing

Crackedback
Is that 34 total timing? And at what rpm ? You said to hook up the vaccum port but what port on the carb ? Full vaccum or the port for timed vaccum? And after the vaccum is hooked back up what should the timing be ?

"All of that" is combo dependent. There is no one set formula for timing. DO what we've told you with what you have and you can find where your initial wants to be right now. Just bump the timing up 2* at the time, until the engine does not raise in RPM anymore. Each time you bump the timing up, bring the idle back down on your tach or tune up gauge to where it's supposed to be. 700 is a good place. Once you get to where the engine does not idle up when the timing is advanced that last 2*, then back it back down that last 2* and take the reading with your timing light. WRITE IT DOWN, because until you can limit your total timing, you do not want to leave it there, because it will have too much total timing. Then back it back down to where it was before and it will be safe until you can get the total timing limited to around 34 "or so" degrees.
