Andrew Maszczak Posted July 16, 2022 Report Posted July 16, 2022 Hi all. My choke housing has issues where the vacuum line attaches and can't get a good seal. AFB - 3726s. Does anyone know if there is an easy replacement part out there somewhere.
John C Posted July 17, 2022 Report Posted July 17, 2022 Hi Andrew, Take a look on ebay and 3721 AFB carbs from 62 thru 65 Corvettes. You can use the choke housing from one of these. You will have to fill about a 3/32 hole on the rear with epoxy and the brass tubes over the choke are slightly longer. You can shorten the tubes with a Dremel tool if you like but I think it will work fine as is. Other than that they look and function the same. Good luck with it, John C.

The line provides warm air to the choke from the exhaust cross-over passage in the intake manifold. Edited July 17, 2022 by regnalbob

Andrew Maszczak Posted October 4, 2022 Author Report Posted October 4, 2022 So...I have since discovered that the choke housing is shared with ford. From a 1958 Ford. Called a thermostatic control. Part numberB8A-9850-B. Found one on e-bay for about $60.00US. Unlike old mate who is selling one that is match to a HEMI for some $450.00.
