So I have what is suppose to be a relative newly rebuilt dizzy.
I have a wide band in the car.
So occasionally it will spontaneously go lean while I'm driving.
Car will be running rich around 12.0 (where I set it) and then be 15.0 or worse.
I think it only happens as I slow down in gear but I'm not certain about this.
If I turn the engine off and restart it goes back to running rich (12.0) where I set it.
This only happens occasionally (the spontaneously going lean).
I'm thinking its the old plunger sticking issue and I need to give it a good cleaning.
(I've buzzed out this system pretty thoroughly in the past)
