I have been having problems with my carbs for a while. She starts terrible, idles terrible, and is generally crap until warm. When she's warm, she is great. Last fall I changed out a low speed jet, and immediately ran better than before when just cruising about 50 km/h. Unfortunately didn't solve the big issue.
Here is the meat of the issue: When I try to set my idle fuel screws, the right side works exactly as the factory intended. Turning the left side has almost no effect on the idle rpm at all. In fact, only when I turn the screw in fully does it change, and then it revs up slightly. I tried switching idle screws, but no change. I also switched the low speed jets, and no change. So I pulled the carbs and took pictures of the inside of the idle screws.
I suspect that my left idle screw isn't reaching the hole to stop fuel from going in, either from wear or damage. I believe that if I'm careful, and drill a TINY amount of material out of the larger diameter of the hole, then the throttle screw with its tapered end will go deeper into the hole and possibly allow me to control my idle fuel again. I could really use some input.
