Art,thanks for the info and the link for the rebuild kits. On a side note,how do you like those Alfas? I was looking at a local Alfa Spider Veloce for sale..looks like a nice clean car that needs a little TLC! Something different from the Mopars,but I,m open to anything on wheels that is fun to drive.

Other then the carters loving to cut out in sharp bends unless you really work them a carter AVS is fine . use 110 needle and seats and you can keep the air valve tension so it snaps back 2.5 tuns from base . Frankly I like the Holleys as I'm totally used to working on them and they can be tuned to perfection. Myself if its a 3310 vac sec run 70 jets frt 76-77 rear and the heavier yellow spring If its a dbl pumper run 71 Frt and 77-80s rear. Whatever you do get it back on the road and blow out the dust your neighbors may not like it but who the hell cares!

I do love them. Yes for sure Alfa's are super fun to drive, manual shift and to get the power out you rev high, so the experience is just great. Handling and balance are excellent. Parts and advice are plentiful (surf around, look in their classifieds and even ask if anyone knows about your Spider on www.alfabb.com) and not expensive. Upgrades are also plentiful. They do take extra care though, like things have to be repaired before they fail..
- My '82 has the fantastic V6 and been very reliable.
- The '94 has the bigger V6 with 24valves, but has electrical issues that are hard to really get completely sorted out. Modern stuff gets complicated. Bummer.

But don't let a '94 sedan scare you away from a nice used Spider! They would be a great start, Good luck!

carter for longetiviy. Holley is finicky sometimes

i think either carb is fine, but im always surprised at how much flack holleys get for leaking. i have holleys on all my junk and none of them leak. they all run good and are trouble free. now, i have worked on some that had issues when no fuel filter was used and there was a bunch of junk in the tank

I haven't had much problems with holleys leaking. Usually the accelerator diaphragm is loose or cracked will cause the leaks. Or maybe they are referring to the needle/seat adjustment? The gaskets here can stick and tear when adjusting float level. I usually put a coat of chap-stick on the gaskets to keep them from sticking and tearing.
The old Holleys with the accelerator pump check ball can loose function if the carb gets dirty and the check ball no longer seals. The rubber check valve on the newer holleys seems to work/seal better. The newer holleys also have the back-fire check ball to protect the power valve.

The carter doesn't use diaphragms for the power valve and accelerator pump so they don't have these issues. The needle/seat is not externally adjustable, so no point to leak, but harder to adjust float level.

Thanks for all the help and advice! I have a feeling that I should be good with either carb. I think what I,ll do is,when its ready to fire up,I,ll put the Carter back on and use that until the car is up and running and all the bugs are worked out. Then as time permits,I,ll try the Holley and see if there is much of a change. I,m not looking for the last 10th of a second or anything like that,but since I have the Holley and probably will keep it,I might as well monkey around with it. Back in the day when I was constantly buying and selling Cudas and Roadrunners and all the other Mopars,it was just normal to pull the original carb and put a Holley on. The GTX is the only one I can recall that I kept the original carb on! It has served me well.

If such is the case, your float levelis low. Raise it up and it won't cut out.

I vote AVS. OE 750 or Edel. 800.

Too high or too low you do not see many cornor carvers using a Carter for the float reason alone. I have over 5 AVS carters and a AFB and there is a bend that they really like to start to die out The Holley and Rochester Q jet don't just the carters I have finally decided to just run the Holleys they are reliable and they don'y care about rough roads or real sharp bends By the way did work out a AVS solution by running the carter as dual inlet but too much involved for the regular car guy

Same here. I have had the same 750 Holley DP on my sons Dart since 1997 and it has never leaked and works flawless. The 850 on my 63 has been on it since 2006 and is the same with never a leak and works great. Carters and Eddy carbs are good too as I have no problem using either. I just like Holley's better on my muscle cars. Ron

You said the engine is basically stock and the carb was the correct one for your engine? Is it in good shape? If so...

Factory engineers spent hundreds of man hours calibrating that carb to work on the engine combination you have. If there's nothing wrong with it, I dare say you'd never get the Holley's cold start, warmup, part throttle cruise, and fuel mileage anywhere near as close as the AVS already is. Yeah, the Holley "might" make a few more ponies at WOT but honestly, how much time do you really spend there?

Trouble is when you raise up the float level it will cut out under hard braking!
