right so , my quad started backfiring and spluttering while i was driving with just a bit of throtle so i took out the carb cleaned it and put it back in and it still spat and backfiring . i replace the carb and now it wont start iv charged the batt full and stuff shes turning but not takeing off . any help any1

 

even though you replaced the carb, is there fuel in the float bowl making it through the jets to the cylinder and getting the spark plug wet with fuel? have you tested for spark? you might've degraded a wire feeding spark when replacing carb.

 

yes there is now but the first carb the float was sticking so i taught it was the cause and iv also replaced the ignition coil and the spark ?
