Hello all. My 150cc Jmstar just hit the 385 mile mark and this is the problem
I am having. When I go out and start it for the first time it starts right up no
problem. Then when I start to ride everything seems to be great. After I would
say 10 to 15 minutes it start to feel as though it is cutting in and out usully
while driving at a steady speed like 40 45 mph ect. I have to work the throttle
to get it back up to speed. Then when I stop at a stop light it will seem to
idle a little rough and will shut off if I do not give a little gas to keep it
running. Then I stop to go into the store and when I come back out it takes a
long time to start it cranks over and over but when it starts it will idle a
little high until I get going and then Its all over again on the way home.


Any ideas before I dig in.(maybe valves or carb???)

Thanks Don
