Carburetor Problem

[Print Bear <prntbear@xxxxxxxxxxxxx>]

OK. Today, Saturday, I have recovered from flu, and, taking large parts of all the advice I have received, I did the following:

Replaced plugs with Autolite 85's (couldn't find 89's, as recommended, and according to the Autolite website, 85's are the ones. The ones that were in the car were Denso, made in (guess). Gap at .35 (That steering column is in the wrong place for plug #7. Then I moved the Cruise Control control arm and it was marginally better)

Cap, cond, and points are new, reset gap to .17, checked firing order and all the wires are new and working. 

New gas filter, checked oil for gasoline.

Then, not wanting to spring for the carb, I hit it with the rubber mallet. Well, I know this isn't really the right thing to do but with all the comments about Holly, I thought it couldn't hurt to try it prior to going out and paying $250 for a new Edelbrock 650 square flange, with electric choke. 

Results:

Runs remarkably better, still got the gas problem--Too rich, black smoke, smooths out at higher rev. Not right.

I'm going to buy a carb. Good bye $250.

More later.

To hook up the electric choke, you just have to run a hot wire from a switched source like the ballast resistor.  The choke stove in the manifold will no longer be necessary.

You can get a 750 or 625 cfm. I don't know which Imperials came with stock. I know that hp 440s came with 750 avs. Either should bolt right on, but you may need the linkage kit. Check out Summit or Jegs.
