Harms Rebuilt '71 Thermoquad - Wondering Idle, Stalls when Put in Gear

I assume nothing. I am not the original purchaser of the rebuild and therefore don't have a vested interest from Scott Smith's point of view. It would be like if you bought a car from someone who bought a car from me and thinking I owe you. I would not make such a presumption but that is just me.
I know what it's like. I'm also not presuming anything. I don't even know what that stupid crap means. It doesn't hurt to ask. He might do it free...he might not. But don't ask. That's one way to never know. My carburetor runs great. So your junk is pretty far down on my list, especially if you don't want to listen to sound advice.

To expound a little more, you act as if the world is coming to an end because the carburetor won't idle. That's a VERY SMALL part of the equation and one that very likely the adjustment I outlined might fix. I would try it first. It costs nothing and may fix it. If not, you've lost nothing.
