Where can I find a selection of choke coil springs?
I have the original housing and choke lever for a 1970 Ford Ranchero with a quadrajet carburetor, 429CJ engine. However, last summer the coil spring stopped expanding and I have now lost it (so no longer know its width and how many coils the original spring had in it). Last winter I experimented with a Chevy big-block choke coil sold by Summitt. I stripped the coil from the Chevy mount and mounted it into my Ford housing. It worked somewhat, but was really too meaty for my application- it fully opened too late, and took too long to fully cool. I also tried a Ford choke coil from a 289. It is a little too skinny- it heats up a little too fast and may not have enough coils to both fully open and fully close the choke on moderate temp days.
I know I can just get a manual choke kit and be done with it, but like Goldilocs and the 3 Bears, I feel like I have tried one coil too big, one too small, and suspect there is one just right if I can find the right coil (I do not care about the housing it may be in). I know I have to do some fabricating, but just need the right width coil spring with XXX coils total in the spring.
Any advice, please let me know.
