Well I have a 2001 tomos targa lx and It has seen better days. Recently It has been acting weird. Once I start to reach the point when it should begin to shift, It sputters And wont shift. I've gone hundreds of feet and it still wouldnt shift.
I first thought it was because i didnt let the engine warm up enough but I have, I bought brand new spark plugs for it too and it still does it. I have to premix my gas and oil (oil pump was terrible). Any ideas on why it is doing that? I have the right mixture I have trans fluid and all that stuff. It also starts up fine. And if I start going faster down hill then I normally do on a flat surface, It starts making the same sputtering noises.
My carb is clean and seems to be working pretty good. since I am getting a car soon I wasnt really bothered with this problem But I would Like to continue to drive my moped untill My car and even afterwards.
