Howdy fellas, I've been lurking around here since I put my bike together in march and now I have a question hehe. I have an 80cc chinese motor. So I couldn't start up the other day so I figured it was a good time to replace my wash rag exhaust gasket, seal the leak I had on the float bowl, and put an O- ring in the intake. So I did that checked for a spark and was ready to go. So I mixed 4 oz of oil to a gallon mixed really well 32:1 I think which is what I've been using all summer and she fired right up on the first try. It' runs really good under a load probably as good as it ever has but when I pull the clutch the idle is screaming fast, the idle screw doesn't have any effect. It's so fast and so loud that I have to kill it right away because something is wrong hehe and I'm afraid it's going to explode. The fuel was mixed really well and it was a fresh can of gas and oil so I don't think it's lean (it was slightly more than a gallon of gas but not by much). The slide in my carb doesn't have the smoothest action and I was leaning toward maybe it was getting hung up on the barrel and not completely descending? Oh and I have the needle set on the second from the top I've always had it there. Any ideas? I was going to lightly sand the barrel and the slide and see if that helps at all. I drained the gas and added another ounce of oil just to be on the safe side.
