Advance timing light question
#23
Are you running with stock coils, cops, or something else?
Some ingition systems will not work with a dial back timing light. I have a high dollar Snap On light, and it is not compatible with my Electromotive ignition. It has a crank trigger with a coil pack per cylinder. I have know idea why it does not work, but Electromotive warned me that it would not work, and they were right. It showed 0 at 10 and 10 at 0 just like you said, but it was way off when I double checked it with a standard light. The timing was retarded by about 40 degrees. I ended up buying a Discount Auto cheapo, and it has worked fine ever since. However, the dial back light did work right when I had the stock ignition.
Borrow or buy one, and make sure it is the same as your dial back before going on that goose chase.
