I have a brand new 2004 Tomos LX, with 292 miles on it. I've been usin a gas addent to keep my carb and engine clean. I recently found out that I should use regular gas ONLY, because gas addents will make my engine run hot. I rode it today and it just cut off on me as if it ran out of gas. It still had gas in it. It barely made it back to my house, and when I got there, I took the fuel line out the carb, and turned the reserve switch off. When I turned the switch back on, Little drops of gas came out of the fuel line. I double checked in my tank, and I could see gas in it, (it wasn't full though). Every time I turn the reserve switch off then on, little drops would come out (It wouldn't run out like it should). How can I solve this problem?
