I think you may need to put a bushing in for the primary throttle shaft after the crack in the base plate is repaired. If the shaft is loose in the hole it will allow air to enter below the throttle plates which can effect the carb tune. Might want to contact a place like All State Carb and see if they can repair it for you.
I found All State Carb in NY. Is that the one?

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

do you have to much return spring tension   you just need enough to shut the valves   any more over time can case damage

Thanks again for checking! I'm keeping my fingers crossed.  If you find it, let me know how much you want for it and the shipping and I'll get that to you.

How would I check or change that?  Also, what seems odd, is that my friend and I both remembered the blades moving easily before we cleaned it.

Any chance it got dropped, or fell off the work bench? The would account for the crack and jammed throttle shaft.

Yep.  My friend dropped it right after we pulled it.  I can't be mad at him since he's using his free time to help me. ; )  Just have to figure out how to we're going to fix or replace.  I've been reading about lots of issues with this carb (fuel leaks, etc.).  I thought I wanted to keep it original but since reading about the issues I'm wondering if it would be better to change it.  Your thoughts?

Change it. You can keep your stock intake manifold and use this adapter to install a square bore carburetor.

Thanks for the link and suggestion!  I at least have another option now.

I have a D3ZF-MA baseplate (auto) if that would work.  Chuck
