I have a 1982 4x4 with what appears to be a stock 22r. The truck originated out of Huston Tx, so there is no HAC valve installed. I am running stupid rich and want to rebuild the carb as that the truck sat for close to 4 years in a barn with fuel in the system and never started. While rebuilding the carb I want to make sure that I have a smaller primary jet in the carb. Where can I, if I still can, purchase primary jets for the stock carb that will allow me to lean out the mixture. I live in the Denver metro area and have high hopes of taking this truck up to the hills which will include crossing passes at 10k-12k feet of elevation hence why I want a smaller jet.

Thanks,
