I haven't been following this thread word for word, so maybe I've missed something.  Has anyone suggested that the distributer cap has a spark track to groung.  They can be really subtle and difficult to see.  The track could be aggravated by some extremely high resistance between disty and plug.  The high voltage wants to find a ground, be it the electrode in the plug or a hair fine carbon track in the disty cap.

DanT. asked:

Did you happen to measurethe dwell? 

The answer: It now measures 35 deg at idle, about 32.5 at1500 RPM. It was 32.5 at idle and about 31 deg at speed when #1 was not firing.Seems like it would have moved the other direction, but it is what it is.Before I started any work (I think #1 was not firing but not sure) it was 40 atidle, 37.5 at speed.

Tomy request for help concerning my daughter's Spyder #1 distributor tower notfiring, thank you all who responded with suggestions. I followed Frank DuVal'sadvice to check the point gap on #1 lobe, then measure the other 5. I foundthat there was a large variation between the gap at each of the 6 positions(0.004 to 0.017). What I have done for now is finesse the gap setting to hitthe sweet spot where all 6 are firing and I have enough dwell to prevent cutoutunder hard acceleration. I am thinking a rebuilt distributor is in my future,once I hit the lottery. At this point it is running well enough to keep me onthe road.>> -- Doug Mackintosh Corsa member since 1996 Corsa/NC member since 1996, Virtual Vairs member Corvair owner 1969-1971 and 1996-on  _______________________________________________
