    hi i was wonderin if any1 has any ideas why my sym jet isnt going properly, ive got it working now and ticking over nicely, i just put a new plug in it and cleaned out the carb but wen ever i get on it to ride it keeps kinda bogging and trying to cut out but if i let the throttle go its alright. so its kinda almost cutting out at high revs. ive tried messin with the idle mixture but no luck.
    cheers for any advice! :D

    I reckon this could be a float problem or a blocked main jet....

    too lean a mixture will cause bogging at full throttle, as well as too rich ;)

    float

    to check the float take it out the carb and see if its got fuel inside it.if you cant see through it give it a shake instead.
