<VV> Tach out of whack and car runs like cr*p

[Lillibridge, Herbert J.]

Make sure you do not use any type of metallic shim. Use only plastic, using
any type of metallic shim to set the gap will destroy the electronics.

In case you did not remenber, there is no dwell with Petronics. You got,
with the set, a plastic shim .030 to set the gap. If you cant find it use
another .030 shim.

 

 Then work on the tach question.

The tach on my 1962 Spyder suddenly is not working properly, as it shows an
idle RPM of about 600 when the car is actually idling at 1000 (via an
external engine analyzer). Likewise, it tops out at about 2500, when the
engine is actually turning 4000+ RPMs. This is a relatively recent
development, right around the time I reconnected the resistor block before
the Flamethower coil. Did I do something wrong that is affecting the tach,
or do these things go bad? If the latter, what years share the same tach for
replacement purposes?

Also, I can't put my hands on the literature for my Petronix Ignitor. Can
anyone advise on how the dwell is set, and what it should be at? The car is
still crapping out above 3000 RPM. Installed new Bosch plugs; Checked,
cleaned and sprayed graphite on the distributor weights; they seem fine.
Found I had a vacuum advance instead of retard on the distributor so replace
that with a used one from Larry's. Checked the dwell and it showed low for
standard car (about 16 degrees), so thought I would investigate resetting
that. Then found I could not find my instructions (buried behind all the
Christmas decoration boxes, no doubt.)

Thanks for all the help this past year. You have made my entry into the
World of Corvairs a lot less stressful and a lot more fun.
Merry Christmas/Happy Hanukah to all.
