Re: question about the dizzy cap

electrical contacts usually corrode, looks like this but i doubt your dizzy would be this serious. just spray it with some contact cleaner and rub it with some sandpaper if that is your problem.

Re: question about the dizzy cap

cap and rotor should cost under 20 if you end up buying one.

Re: question about the dizzy cap

I know how it is with cash being short but I would recommend cap, rotor, wires and plugs. It will make a huge difference. Sometimes those caps crack and let in moisture. It seems to just find its way in there.
I learned my lesson about buying the cheap stuff too. I once but cheaper parts(even with lifetime warranty) and they didn't last that long. Yes they were warranteed but who wants to keep changing them out?
