Is there anybody out there that can give me an idea of what I can do to my Weber carburetor to get it pass emission here in Idaho what I have is an 1980 4 x 4 pickup with a 1982 22 R motor and a Weber 32/36 carburetor that doesn't want to pass emission at idle for hydro carbons. Any help would be greatly appreciated.
I don't have a Weber, but the process should be similar to the FSM one I've been using with the stock carb:
Get a timing light, pull off and plug the vacuum advance on the distrubutor off, and check and dial in the timing. Timing is usually been the root off my not passign emissions.
Next get a tach on the motor and dial in the idle and fuel mixture. This can be accomplished by uping the idle and leaning out the mixture till ya hear the valves get a bit noisy. Then checking the tach slowly making it richer until the idle doesn't go up anymore. Then set the idle and head to the smog shop.
I go through this with my carb'd motor every so often through the smog check. My carb must be getting it screws loose or something after a while <img src="/forums/images/graemlins/lol.gif" alt="" />
