i've got a 64 vette, 365 with 2818-1 carb, petty much stock with the stalling at stop signs problem. i've gone back and read treads with the same problem. most say its a problem with the float level. checked and gas is right up to the top of the holes. another said maybe the coil. i put in a new coil. another says leak bettween carb. and manafold, so a put a thicker gasket between them. my problem is stillthere. it does not stall until i've been driving for an hour on a warm day. after it stalls at stop sign it will start right back up, everytime, but will not idle. i can let it sit for 5 min. and start, and then it will idle. i've seen many treads on this, but still have not found the right fix. the car runs great other than the no idle thing. HELP!!!!!!!!
Is the choke hooked up? Have you tried adjusting the idle up after the engine warms up?
I'VE GOT HOOKER HEADERS ON HER SO THE choke is not hooked up. i didn't cap it off on the carb. i've got the idle at 800-1000 now. i warmed it up and set it at 7-800 and it works it way up to 1000 later. should i cap off the hole where the choke use to go to the manifold? or maybe ajust the choke so its off all together???

I had this exact problem with my 2818-1 carb. It would idle for half a minute and then die. Never got around to fixing it as I bought a 383 stroker motor and new Holley 770 street avenger. Now you have to get the motor up to full temp or it will idle a little fast. Has an electric choke. Good luck with finding out the reason for stall at idle.

maybe that what i need to do, put the carb. on the shelf and get a new one?

I's try capping it off on the carb. I don't think the hole in the manifold will make any difference but I guess it wouldn't hurt.
Go for a premium brand like Sunoco or Amoco. Gas may be boiling on you. Had heard Hess gave problems.
Also make sure your vacuum advance is working. Install a vacuum gauge by console and see what it does as idle rpm varies. If vacuum drops below a certain point, vacuum timing will retard and rpm will drop further.

use either IBP OR PHILP 66 . will take a look a vacuum. thanks!!!
checked and gas is right up to the top of the holes.
You might try re-adjusting the floats, as the fuel in the sight holes should be right at the bottom of the sight holes with the engine warmed-up and idling. Good luck.

i'll warm it up good and then check the float levels. thanks Dave
One other item to check is the proper VAC for the distributor. A 365 HP engine uses a cam of high overlap which produces a rather low vacuum.
You ll want a VAC that pulls full advance at low vacuum like a VC 1810 stamped B28.

I had the same symptom with my holley. Turned out to be air-fuel mix. I didn’t have a vacuum gauge so I followed instructions provided by another forum member (landshark 454)
“First, warm up engine. Then lightly close both air mixture screws on each side of carb, and open both 2 turns. Fire the engine and turn them in until engine slows down slightly, then turn the other way until engine slows down slightly, then turn them back the other way again until your best highest idle. Try turning both in small increments as you go to keep both sides as close to each other as you can.”
If you’ve never done this before, it sounds a little weird but my car has never run better since I made the adjustment using the above procedure. Good luck. Bill

How close are the Hooker Headers to your fuel line up front?.Boiling gas will do it every time. Or Possible your needle and seat (float adj)are sticking. Is there any internal dripping from the carb when running. It should not be dripping gas when you idle the engine. Idle circuit may have a little trash in it. I just recently last week had a 69 in the shop with the dripping problem, flooding out at idle and Sun had a 66 BB that just would not stay running but started fine. The floats adjustment was the problem on these.
Clean and put a kit in your carb and you should take care of it.Holley's can be very touchy when not driven all the time.
Phenolic spacer is akin to bakelite, a non metallic spacer to limit heat transfer.
