Weird ignition problem
Posted by: Bluebrier ()

Hello guys,
Haven`t visited Corvair center by a long time but, want to share one of the weirdest problems I've had dealing with Corvairs.
Yesterday, while driving "El Andariego" (67 Corsa clone) noticed some lack of power and rough idling associated with ignition. Suspected from a plug so, this afternoon did the checking to isolate the bad plug (# 3), took it off and looked fine but, using a new one tested for spark, before installing... no spark, oh!!, maybe the wire. Retest with a good wire... still no spark, changed cap & rotor.
Resuming...good plug, good wire, good cap & rotor and no spark. Rotated and checked the 6 small magnets on the donut (Pertronix) and...nada !!
Tomorrow morning will change for a full spare distributor and see what happen.
PS. Discarded coil failing as it is providing good spark to the other 5 cylinders.

Cheers !!

Good to see you post!

That is a strange one for sure! Has to be the Petronix?

Bent shaft in the distributor moving the magnet too far away to pickup that one cylinder, seen it before.

Find the magnets and put them back in the holder, I did once and it worked just fine. I also put the retainer ring on better than the factory did.

Good to hear from you Daniel. Haven't seen you in awhile (Tacoma?). I suspect your issue is... PERTRONIX

Did you test the new plug on a different cylinder's wire? Unlikely, but it could be a bad plug out of the box.

Sorry guys by not repling so soon as I would like. As planned, put another distributor with Pertronics and problem went away. Enjoy fully the very last days of this marvelous 2017 !! and... be prepared to squeze all the best of the new year that is knocking at the door !!!

A big hug for everybody.

Daniel
