I have a 64 catalina with 67 400. When i step on the gas the car just bogs/dies and a second or two later, it kicks in. Hopefully someone can help me as this is getting a little frustrating. It has an edelbrock intake with a carter carb. Is the carter a good carb or should i bag it for an edelbrock or road demon? thanks for any advice.

Sounds like the internals of your carb are toast. Edelbrock all the way. Buddy of mine has a '66 Cat Safari that does the same. Tore the "new" Autozone Rochester 2bbl carb down and found JB weld holding stuff together.

64cat - first thing is to verify whether the accelerator pump is working. To do this start the engine (now you know the bowls have fuel); stop the engine; remove the air cleaner; hold the choke butterfly open; work the throttle from the idle position to wide open one time, while observing the pump squirter (beneath the choke plate). If squirter does not squirt (and carburetor is reasonably correct for the car) rebuild the carburetor. If squirter does squirt, look elsewhere. A good 'elsewhere' place to look is the setting of the idle mixture screws. Depending on which Carter you have, screws should be out from one half turn to an absolute maximum (on newer carbs only) of 2 and one half turns. Probably 1 turn is about right. If screws are out too far; correct, and reset idle RPM (hot). Then test the car.
One other thing to check would be the type of intake. Intakes are square-bore or spread-bore. The type of intake should match the type of carburetor. Jon. Good carburetion is fuelish hot air.

Thanks for the help, I try that this weekend. FYI I have an edelbrock performer intake on the car. I don't know what type of carter carb I have. I did pull the numbers off the mounting plate- 9635 SA 3465- If anyone knows what type it is, that would be great.

9635 is a 625 CFM specifically calibrated for a 400 cid bowtie engine. Expect to have a hesitation from a stop sign with an automatic transmission and a Pontiac engine and no high stall converter. Also expect to have a hesitation when moving from the primary metering system to the secondary metering system under certain conditions. These problems can be overcome, but machining is required to eliminate either or both.

Carbking,
First off thanks for all the advice. I don't know much about carbs and this being my first pontiac. Would it be best to dump the Carter AFB and go for with an Edelbrock or Road demon? If so, which one and what size. Thanks again for the help Karl PS: here's a link to pics of my car that Ponchopio has put his site. Great site, check it out. http://public.fotki.com/ponchopio/1964_pontiac_catali/ <BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>Originally posted by carbking: 9635 is a 625 CFM specifically calibrated for a 400 cid bowtie engine.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
