You may want to reference AGK specs for setting up the Mikuni 22. I run Mikuni 22's on my 68 Yamaha 180cc twin cyl race bike. At sea level, I run 130 Mains and 12.5 pilot with Needle clip in center for a little more grunt at corner exits. Richer at lower RPM. A Mikuni 22 is just fine for the GX 200cc, great carby. Sounds like you got it good. Keep an eye on your plug, you might still be somewhat lean with a #40 drill size at full throttle. Cheers, mate
Thanks for the advice about your jet size for a 180cc engine. I've been increasing the jet size and inspecting the plug daily. I have it up to a 1.27mm now and it runs better than ever and the plug is the proper dark cream color.
