Thread: Rochester 2bbl needle valves

Tweet

Pat,

Thanks for the reply.

Not sure if we are thinking of the same needle valves. These are the IDLE jets at the base of the carb. All the idle jets I can remember seeing are solid brass, about an inch long. Very susceptible to being ruined by overtightening, and I don't remember ever seeing any that had a soft viton type tip...(doesn't mean there aren't any, however!)

You mentioned a needle valve body at the top of the carb...are you thinking of the float bowl needle valve?
Seems like I have seen "viton tipped" type needle in float bowl assemblies.

Was thinking...don't some Carters and/or Rochester quadrajets have metering rods the are raised and lowered to richen the mixture? Think metering rodwould be likely have a viton tip, rather than a solid brass tip as they would be inlikely to have some ham hand overtighten them.

Thanks

ok yep them are only rochesters holleys would not work carters ? maybe Qjets may work to if old ones can not be found find someone with a lathe and clean up the old ones or chuck them in a drill press and hit them with a small file till most of you marks are gone that could be a werd thread pitch on the old ones so do not chuck them in very hard if your going to try to clean the seat part up . the Qjets and AFBs and carb with power rods are solid metal

Monday give these guys a call. We have had them restore several Rochesters from a tripower setup and have bought several complete carbs from them. Good people and they carry just about everything carb related.
