Don't Feed the Carburetor After Midnight

I know, I know. I said I was going to sell it and here I am about to talk about another repair I'm doing on it, as if I'm going to keep it for a while.

The truth is, I keep going back and forth on it, and I have no idea what I'm going to do, except probably rebuild the carburetor this weekend.

Yes, I know, I know. I said it had stopped stalling after I fixed the vacuum hoses. It was true... for a while. But the mysterious stalling gremlin has returned. It's still better than it was before the new hoses, but it appears that the mechanic was not as full of it as I thought. And it's easy to find an el cheapo rebuild kit. If that doesn't work... well... then I'm stumped.

I got the rebuild kit last night. I started undoing things from the carburetor and got it about 1/3 of the way torn down, and by then it was clear to me that it's been rebuilt recently. All the gaskets looked good, and the replaceable parts that I could see were obviously new. ::sigh:: I'm considering not doing the rebuild after all. I'm reminded that the engine ran great when I had fixed a vacuum leak. Could it be that the now-increased vacuum has caused another leak to develop in a weak spot, that's not in the carb itself? Is it a matter of tuning the carb some more?

Returned the rebuild kit, got the carb put back together, but I must have borked something in the process. Cold starts take way too long, and the stalling is as bad as ever.
Not looking good.

Normally the choke is not adjustable, but I slightly broke the part that keeps it in one place. So now it's adjustable. I tweaked it a little and a cold start didn't take as long, but it's idling a little too fast so more fine tuning will be needed.

Guess I might as well post this now. Maybe I'll get something flammable and test for vacuum leaks this weekend.
