I want to change the Accel distributor currently in my 63 which does not have a vaccum advance. If replace it with a GM tach drive with vacuum advance where should it connect to since the carter carb on it does not seem to have a conection for it?

Or should I get a distributer with no vaccum advance on it?

no plug on the intake you could pull and replace ?

I would use the vacuum advance. If necessary you can always put a T in the vacuum line to the choke break cannister and tie the vacuum lead to it.

You merely need to get one of these hollow carburetor studs as was done on many of the early base model Corvettes...

No plug on the intake that I can see..thought it should connect from the vac advance to the carb somehwere?

Where should it connect to on the Carter Carb? I do have a brass plug on the back of the carb...can it go there?

If you don't like my manifold stud idea in the above post - then, if your brass plug is the standard size (1/4" NPT) in the rear, base part of the carb, this Paragon fitting is explicitly made to solve your problem:

Do you have a working choke on the Carter with a vacuum pull off can and rod to the choke plate? If so, it should have a vacuum line leading to it. A vacuum "T" can be installed in it. If this is an original carb it shouldn't have electric choke.

I have a Carter AFB on my '63 and there is no vacuum line to the choke. The rear fitting goes to a PCV valve from the carb and the vac advance goes to a front 'hard line' as shown. This is not the original intake/carb for a 250hp (I have those stored) but the carb shown is correct for a higher HP engine.

Can I put the vaccuum line in the back of the carb where your line is going down the back of the engine?

Can you identify the carb?

Frankie the Fink

You keep asking the same question different ways - yes you can. You have the Carter WCFB carb for a 250hp engine and NOT the Carter AFB carb as I show in my picture.

Buy the fitting in my post #7 above...

It is SPECFICALLY made for your purpose.

It's even designed in two pieces so you screw the big part into the back of the carb and then separately screw the vacuum line nipple in to that piece so you don't even have to remove the carb from the engine.

One question, three choices. I'll that any day.

You also need to plug that vacuum nipple at the top of the carb (pic 1) if you aren't using it with a plastic cap. Apparently your choke is wired wide open or something (pic 3) - no need for that but if it works for you then leave it be. You'll just have to baby the car some when its cold...

If you put a vac advance in there you will have to "clock" your distributor to make sure the can is under the ignition shielding if you have it. You can start a new forum thread on that when you reach that point if you can't figure it out.
