I recently installed an electronic ignition replacing the point and condensoer. Now I want to check the timing but I can't find any timing marks on the fan! I see the notch in the housing but even when I align the rotor to the #1 lead and look at the fan I cannot see any timing marks not the TDC mark never mind the 27.5 before TDC. Has anyone run across this and what is the solution?
Thanks |

Good point, sometimes you can catch a view of the timing mark(s) with a mirror from the other side of the fan housing.
Also, some flywheels may have TDC marked too but this may require pulling the rear engine tin slightly out of position or viewing from below the car. Actually, some people prefer marking the flywheel & will mark TDC and 180 degrees out for such things as valve adjustment procedures (can tell where the camshaft is supposedto be without crawling out from under the car. |

Thanks for the suggestions but my 914 looks like it has a cast aluminum fan casing. There is no tin work to remove at least while the engine is in the car! There are two very clear timing marks both way off so far off that if I line up the TDC mark with the v notch the rotor point halfway between leads to cylinders 3 and 4! I think I am faced with gettin gunder the car with mirror and searching for mark on top of transmission which from the descriptions I have read seems like a virtually impossible task! |
