As for mixture adjustment, if you have it 3 or 3-1/2 turns out, it acts like its too lean, cover the barrels with your hand, and the idle picks up and smooths out, so you richen it, I've tried it every which way you can, from 4 turns out to 6 turns out and everywhere in between. It still acts like it is starving, yet the exhaust smells like fuel and it burns you eyes.
But it ALWAYS bucks the same, no matter how the mixture adjustment is set.
Cold start up is perfect, one pump to close the choke, crank, fires up, idles up to about 3000rpm until you kick off the step-up. Idles great, idles great when hot. Drives good if you are on the gas or engine braking. Cruising sucks, starts bucking. You have to keep the motor under load for it not to buck.
Also, once and a while when I shut it off, the engine fires back up (With key off) and will runs for 2 or 3 secs and then stalls (Probably just because fuel is igniting from the heat) I don't have any anti-dieseling solenoid on the carb. It doesn't diesel, it just starts back up lol and then stalls.
standard starting point for weber should be about 2 turns out...
