We run the stock ignition system in our cars. However Dyna makes a red box system that is close to their dynatek 2000 system for the bikes but it is not adjustable for the race car.

Well, that's that.

To see the bits in question, you need to look between the back of the tach face and the front of the white plastic housing. At first glance it could be taken for a return spring, but I think it's too light to be one.
As to why the cars do not seem to be affected , ummm, I don't know.
I'll post a pic of the tach I have if you don't find it on yours,

I've got a spare tach that I pulled apart for a look, but I cant see these contacts you mentioned in an earlier post. All I can see are two return springs that have wires connected and a thin bit of black plastic between them









The white plastic piece with the wires wrapped around it has a pin that connects to the inside of the bottom spring, and another pin higher up that goes through the black piece and connects with the inside of the top spring and they all turn together, but as for contacts, you've lost me. Can you point out what you were talking about Earl
