Timing

[twayne24365]

hey guys, quick timing question
It’s a 1969 d100, truck seems to run good just checking over a few things since I don’t know a bunch about these little engines.

So with vacuum advance plugged im at 10* @ 750-800rpm idle, and about 35* @2500rpm

With vacuum advance working I’m at 45* @2500rpm does this sound about right?

 

[teringer]

yes

 

[Biff]

That’s a lot of total 45*

 

[Plymouth 65]

10-15 deg. initial, total 35 deg. Generally speaking. 65'

All-in by 2500 might be a little early, but if it doesn't ping it's perfect.

Yea I’m not to up on the whole vacuum advance and all, everything else I have is all mechanical and locked out, but yea no pinging or anything.... only problem is sometimes hot or cold it doesn’t fire right up... could be a fuel issue too
