Hi folks, I'm rebuilding a Holley 1940 for a '66 Mustang straight six. When disassembling the carb there was no evidence of the ball & weight in the carburetor. My rebuild kit contains the ball but no weight which I'm assuming was lost by a previous owner. Is it possible to get a replacement weight from somewhere or would someone here happen to know the specifications for it (material, length, diameter, weight) so I can fabricate one myself? The car did run without it, but of course I'm rebuilding the carb for a reason, not sure how the absence of that ball and weight actually effect it though.Thanks for your help,Grant
can you post a LIST number off the carb... i have a holley parts manual at home.. where i can get at it probably tuesday night... if somebody does not describe the check ball weight you need.... there is a small .. very small chance that holley may still have one... if you have a check ball.. its probably aluminum.. just slightly smaller than the hole it fits in.. sometimes they have 3 flats to allow the fuel to flow around.. you might be able to modify an old needle and seat Needle out of some other carb where you replaced it.. i did run across this site... but as many parts they have for various versions of that carb.. they don't show that one..https://buy.walkerproducts.com/carburetor/components/holley/holley-1bbl-1940-1-carburetor-components.html
Thank you. The numbers stamped on the carb body are-4694-23185I do have the replacement ball in the rebuild kit so all I seem to need is the weight. It's beginning to look like I may have to just "fake it" and fabricate something myself like you've suggested. Thanks again, Grant
List R-4692-2AAA is a replacement carb for Ford 250 CI motors for 69 and 70 models...holley replacement part # 40R-493 is the holley replacement part number... item 61 on ill # 38-1 called Pump Discharge valve weight...
Thanks folks. I've had no luck locating the part and ended up cutting a piece off of the "shaft" of the old choke diaphragm assembly and using that. Seems to be working ok so far. Thanks again for your assistance!Grant
