Does anyone know where I can purchase a #2 choke diaphragm and bracket (otherwise known as a secondary carburetor choke pull off valve) for a 1984 RX-7 GS 12A 1.1L, Nikki 4-bbl with a 5-speed manual transmission? I am waiting to hear back from Mazdatrix (part not listed on their website). Autozone apparently used to carry them (Duralast CP360), but don't have any in stock at the moment. I can't seem to find one anywhere. Perhaps there is a universal choke pull off that will work? Please let me know if you have a source or know of a compatible model. The junkyard is my last resort. Thanks!
