Timing Question

[webebob]

It looks good to me!
Put the vac gage in the car where you can see it, and go drive. You will soon see why all is OK.
At high power settings, the vac drops and the vac advance goes completely away. Total timing comes back down.
The extra timing above normal total timing while cruising is what the vac advance is supposed to do. It is good for 2-3mpg. My timing tops 55 deg on the hyway cruising.
One thing you should check in a hi-perf car that has vac advance. With the engine off, distrib cap off, suck on the line going to the vac adv and see at what vac setting the vac advance starts moving inside the distributor. Then put everything back together and go drive with the vac gage hooked up where you can see it. Check under hard acceleration, as the rpms come up, that vacuum never comes up high enough to start advancing the vac advance. This would be real bad. Most people that have this problem, diconnect the vac advance. The solution I took was to hook a switch at the throttle that disconnected the vac adv at half throttle. Either way, having the advance pull on at full throttle is not OK.
