I have a '74 914 with dual Weber 44s and a Pertronix Ignitor distributor, with no vacuum advance on it (or mechanical as far as I can tell). Pertronix says that there is no dwell setting for their distributors. They said I would be fine using a static timing technique, but I would be more comfortable using a timing light.
My question is, how many degrees before TDC to I set the timing? Or, am I missing something? It seems I need to know this in order to set the timing correctly. Thanks for the help. Ken |

Get a 1.8L dizzy and maybe have it re-curved.
Static timing is for getting the engine to start. Then the timing is set to the correct value with a light. Mechanical advance is built into most all distributors and consists of weights and springs that you can't see until you remove the breaker plate. You will have mechanical even if it's an 009. Vacuum advance is for emissions and fuel mileage. |
