Yeah, the springs under the pistons. They will help you tune the part throttle fuel curve and are ice to have for that. The stripped jet will cause issues as it will alter the way fuel flows into the jet and change the fuel curve. As for the accelerator pump housing, the side that sees fuel needs to be sealed or it will leak.
The ring gasket on the pump was nowhere big enough to seal against the walls I don't think. I mean it was pretty loose.
If the carb acts funny ill look into buying new jets and find a way to remove the old ones somehow. If that seems like it could be the problem.
DAMNIT. remember how I said that my drill caught the towel and flung carb parts everywhere? well..Im thinking the choke rod was on that rag because I cant find it anywhere. I dont know what to do...unless someone is parting out a carb, i dont see these for sale anywhere. I have some rod the right size i could bend to the right size but the problem is...I dont know what the right size is...
ugh...anyone got any advice? :evil:
i see mr. gasket sells universal connecting rods (just a straight rod) so you can bend your own and make one. I'm guessing maybe its not that big of a deal to make my own? If the measurements are within spec I might be okay...right? the only rods I see for the choke that are sold seperately (or at all) are edelbrocks quadrajet line. I see alot of holley parts but edelbrock....man...
I would just go to the junkyard and look for a mid 60's Buick with a factory Carter AFB carb on it. It may have the rod you need on it. Or, just look at EVERY RWD vehicle in the yard and see if any of them have your carb on them. I can't tell you the number of Edelbrock and Holley carbs I have found in the U pull it yards around here. Then again, try E-Bay and Edelbrock as someone may be parting a carb or Edelbrock may offer spare parts for this sort of thing. Try E-Mailing them to see if they will sell you just the rod. Also try using Carter AFB parts as your search term instead of Edelbrock as they are pretty much the same thing.
thanks, im gonna try...I doubt my junkyard has anything, you seem to have a cooler junkyard than me.
so i take it you wouldn't recommend trying to make one?
i really wanted to see if my rebuild was worth a crap 🙁
You can try all you want. I would try, but realize it is not necessarily end in success. I used to have one with leftover parts that I couldn't save, but I let it go when I sold off my 1973 Javelin AMX.
okay good news.
my dad found the little rod on the ground outside. I got everything back together and on the car. The car runs much better now. I can completely back off the idle screw and the car runs with no hesitation. I was using my vacuum gauge but wasnt really getting anywhere, after turning back and forth I lost my "spot" with how much fuel I was adding. I leaned out the mixture a bit when I saw smoke coming out the exhaust however. I had to leave the timing way advanced because when I try to bring it down to about 14 it back fires out the carb.
my main concern is that the fast cam idle plate doesnt seem to engage like it should. Im not sure if this is more the job of the automatic choke or what. but I have to put the little "cam" on the screw with my hands to get it to go there, it doesnt seem to go by itself.
overall I am very happy but I think I've hit a wall with my tweaking, I did my adjustments by ear right now until I can get a tachometer and see where I'm at with everything. the car is much more responsive than it ever was before. I still need to go back in and probably change out those jets eventually and if its recommended still..the step up springs. Also I need something to measure degrees so i can see that my secondary valves are opening the proper amount.
try using a different vacuum port. you might be on a timed or ported source. the large ports for the pcv and brakes are best.
i know that when i tuned my car i was making too large an adjustment and wound up hunting back and forth. when i went to 1/4 turns i literally heard the engine fall in to tune.
pull a couple of spark plugs and check their condition. they may have gotten fouled. too retarded a timing usually just causes low power od missing and stumbling. over advanced timing usually causes knocking and backfiring.

well i'm not saying it was running poorly...I just dont feel like I can get it exactly where it needs to be until I have a tach so I know its at the right rpm in the first place. where does your car idle at RPM-wise? or does the RPM depend on the mixture...man...im confused. everything depends on everything else I dont know where to look for a starting point.
i was also curious to know/see how you have your TV cable hooked up? It looks like I may need to buy a different bracket for the tv cable and throttle. I couldnt really find a spot on the linkage to hook up the TV cable stud that I bought either. the tv cable needs to be near the throttle right? since it needs to be on the linkage where it will be moving towards the firewall as the throttle opens?
tuning my engine is a loooong story in full but here are some highlights:
could not get it tuned right, got a new carb. ran better but i still couldn't tune it. pulled some plugs and they were fouled from the previous carb and not being in tune. cleaned up the plugs and got it in tune.
like you said everything depends on everything. don't worry about your idle speed too much right now. just set it low where the engine is still running even.
idle speed will be affected by mixture in that if the mix is wrong the engine isn't running right and will usually idle lower and rough. when you get the mix right the idle will probably go up a bit.
my idle is about 850rpm in gear.
as you step on the gas the TV stud will move torwards the front of the engine. the TV stup is usually on the top of the linkage and the throttle on the bottom, IIRC.
