Re: [ihc] Weird engine problem - calling the experts

Scott,
   Here is the PN for a NAPA Points dizzy.
Holley Points Distributer:
  48-44821   $111.30
  Note: Core deposit is large
   take the old one with you.

Make sure you tell the guy you want the HOLLEY one, that number will also
come up with a Prestolite points dizzy that uses the Prestolite cap and
rotor (read expensive) and a different set of points entirely. You don't
want the Prestolite one. Take your old dizzy in as a core. Most  stores will
not care if it is not a match, so any one, a Gold Box, or Prestolite can be
cored for the Holley.
   oh that price is about 5 years old, so your results may vary.

Ok, thanks for the help so far. I haven't been out to the garage but here
is a response to some of your ideas:

I had taken the intake to the machine shop. It was hot tanked, shot blasted
and I think I had it magna-fluxed at the same time but I can't find the
receipt so I'm not sure. I don't remember anything about there being plugs
underneath so, if I end up pulling the intake, I will check these.

I have removed the EGR and put a plate over the opening. Could this be
causing the problem?

I've also heard you can use propane to do this. Has anyone tried this?

Yes, that is something I will check out. Maybe I will just get a new
distributor. Anyone have any good sources for these? Can I just order one
from NAPA?

I think this answers most of the suggestions you had. Some new stuff for me
to check.

Thanks
Scot
