Distributor Installation - Don't Just Drop It In
|
At the top of the distributor lies the advance mechanism. It mechanically controls the ignition timing relative to rpm. For a racing engine, this often works too slowly. Advance kits are available that have different-shaped weights and springs as shown to the left. Another option chosen by circle trackers is to lock the advance. This can be done by welding the two top plates together. However, the plates must be in the correct position to each other, or the rotor point may not align with the terminal in the distributor cap at the time of ignition. This can cause a misfire. A better way is to get an advance lock-out plate (arrow) made to fit over the pins and correctly locate the plates. View Related Article
