Pony engine

[MrMark]

80 Pony engine. Turn switch on and there is power to the coils. Push the starter button and pony starts but quits when releasing the start button.
Have a test light and there is constant power at the coils. ????

Condition of plug wires, plugs, and points? Condition of fuel tank, carb, and air intake?

If there is constant power to the coils, then you've eliminated a possible cause for failure to run.

Have you jumped around the switch to make sure voltage drop isn't too much when starting?

Bypass resistor/circuit is kaput.

When you say there is constant power at the coils, DO YOU MEAN ANY TIME THE IGNITION IS ON OR ONLY WHILE YOURE CRANKING THE PONY?????????

It should ALWAYS be on if Ignition is on (if points closed around 4.5 to 5 volts) and while cranking if the ballast and by pass is working at a higher voltage (say 5.5 to 6).

I think Frank and others when using the new pony coils eliminate the use of the little on switch ballast and just use it full voltage all the time ???????????
