ok, new guy here. I have an 87 Toyota pickup, put a new fuel pump, and Weber 32/36 carb on. Got rid of all the emissions BS. The truck is running really rich, I've tried adjusting the A/F screw, but it runs the best with the screw all the way in. I've sprayed starting fluid around intake to check for leaks. Now if I spray some in the air cleaner, it actually bogs down. I would think that would make it rev up? I've replaced spark plugs as well. Had timing set at 12 and at 0 and no difference. Anyone have any other ideas out there??
