this is what happens when people dont check fuel pressures and fix air leaks and jump right in and start adjusting the mixture.

the fuel pressure "can" still be tweaked even thought it has not been modified.
but first you want to check the pressure.

it could just be that someone tweaked themixture adjustment, although from what i have found, idle adjustment does not have as big of an effect at cruise.
so here you really need to connect to something that can chech your AFR's.

the plugs.
if it is rich and you let it idle before shutting it down, you are not getting a true rreading of whats going on.
how old are the plugs?

with that said, when it comes to messing the mixture, you want to make sure your air leaks are fixed, fuel pressures are where they should be, and the ignition is the best it can be.
new plugs, cap and rotor and good wires. then make sure your timing is correct and the advance is working like it should. then mess with the mixture.
(i know, you have no dist).
