I inadvertently discovered this issue where all four idle mixture screws had backed out from the 1.5 turns out that they were set at. The carb is Quick Fuel Street Q 950. I re-tested this again yesterday when I set them back to 1.5 turns out and went for about a 6 mile ride and again all 4 corners were out at least two turns. Is there a way the keep these where I want them? Blue Loctite?
