my kawasaki bayou 300 wons start unless i spray fuel into it i cleaned the carb adjusted the vales checked timing checked spark and put fresh gas in and it will just backfire and has een caught fire any suggestions on what to do

 

Did you rebuild the carb with new parts? Often times the pilot jet gets clogged with debris and won't allow fuel to travel through. You should be able to see light through the pilot jet.

 

i cleaned both jets kept old parts because they looked in good shape i can see light through both jets
