Re: carburetor issues?
It was doing quite a bit of 4 cycling before. It ran OK, but using the left adjustment screw really dialed it in. Gained about 3 mph afterward. It runs a lot smoother also.
I don't have any real steep hills in my area, but the inclines I do have are no issue at all with my set-up (66cc Skyhawk, CNSV3 carb, 44 tooth sprocket, and a home fabricated exhaust system)........still pulls 30mph up the inclines in my neighborhood. I also run a 50:1 Echo 2 cycle mix.
Good luck in ironing out your little kinks!!
You're never lost until you run outa gas.
