85lebaront2 Posted June 20, 2018 Share Posted June 20, 2018 Interestingly my emission label simply says US EPA for 1986 model year heavy-duty vehicles, no reference to 49 state or non-California. AllData shows 2 different vacuum and vapor hose diagrams, one CA specific and one except CA, they are not easy to read being a black and white snake's nest of vacuum lines and vent hoses.

You adjust the idle mixture just like you do with any Holley carburetor. You need a warm engine, a screwdriver and a vacuum gauge if you really want to be finicky. You ready?

I may remembering wrong, but I believe these are small Allen head (they are in the throttle body, 4 of them) and are a royal PITA to get to on a 460.

Changing plugs, wires, cap, rotor, pcv, coil, air filter (and compression test) while I'm at it, today. Gonna adjust the carb next week. Trying to hunt down accurate idle mixture procedure ahead of adjustment next week. Link to comment Share on other sites More sharing options...

Gary Lewis Posted June 21, 2018 Share Posted June 21, 2018 Thought so. In that case you can't just adjust for max vacuum. That's why they introduced the propane method. It is really confusing that they say the trucks above 8500 lbs don't use the propane method, but then they don't give the proper method. Bill - Is there a rule of thumb? Like "Find max vacuum and then lean the mix by 1 turn"? Link to comment Share on other sites More sharing options...
