Where is the distributor pin on gofastforless distributor advance?

There is a pin that sits in one of the slots to limit travel. To change slots you simply remove the armature assembly turn it 180 degrees and reinstall it so the pin is in the other slot. The slots are numbered as to how many distributor degrees it will pull in, double it to find the amount of crank degrees.

How does a distributor work in a ignition system?

The distributor as fitted to conventional ignition systems does not just distribute the spark amongst the cylinders and switch the coil; it also contains a centrifugal mechanism that advances the ignition timing automatically as engine RPM rises.

When does the distributor advance add timing based on RPM?

The mechanical adjust timing based on RPM where the vacuum adjusts timing based on load. Under high load, WOT, performance conditions there is almost no manifold vacuum so the vacuum advance does nothing. The only time the vacuum advance adds timing is at part throttle, low load conditions when there is manifold vacuum.

How is the distributor Connected to the manifold?

A tube is connected from the manifold to a sealed diaphragm in the distributor, which in turn is connected to the distributors base plate.

What should the Ping be on a Buick engine?

If you are running a lower compression engine, you may not be able to get a ping. Do not exceed 55 degrees total advance. Total is initial plus mechanical plus vacuum. This means you are probably looking for close to 20 degrees of vacuum advance. The closer you can get to the 55 degrees without the “ping”, the better your mileage.
