Hello fellow Poncho-philes

I'm in the middle of a rebuild on a stock AFB off of a '67 400 (it came out of a Bonny). I want to use it on my 326; I also have a factory manifold for it. In addition, I have an AFB off of a '66 389 GTO that I'm using as an "example" for when I reassemble the choke, secondary and throttle linkages. I will also "can" the throttle cable adapter off of this carb to replace the ball-stud used on the Bonny. I have torn the carb down *completely* and I need to find a source for the special screws that hold the throttle and choke plates to the pivot rod. Anyone have a recommended source for stuff like this? Also, some jetting questions: I have an AFB "strip kit" that will allow me to modify the primary and secondary jetting and the step up rods. Since this is a smaller engine(less air drawn thru carb, I figure I will need to go a bit leaner on the pri and sec jets and step up rods. What would be a good ball park initial jetting setup?

I know, I shudda gotten a Q-jet manifold and carb....

Thanks for any help you folks can pass along.

Mike, try Jon Hardgrove at the Carburetor Shop in Missouri. 573-392-7378. He also has a website at www.thecarburetorshop.com. Ames Performance also sells his rebuild kits, which include most of the screws if you get a level 2 kit (I don't recall if the throttle plate screws are included). I can't give you an answer on the jetting, but Jon can probably get you close. Bear in mind that he will probably tell you that using a carb from a different engine will require all kinds of internal recalibration (bleed sizes, etc.), but I think you can get close enough with jet and metering rod changes. Jon occasionally posts on this board as "Carbking."

FYI~ I once bought the AFB rebuild kit from Ames: the throttle-plate screws were NOT included in that kit. If you must have new screws, find a machine shop in your area and if they don't have them, if they're nice enough they can tell you where to get them. Good luck!

66Bronz - there are two levels of the kits, the second level does in fact contain the throttle screws, and LarryF - you are correct about the airbleeds. Jon.
