Its backfiring thru the intake , idles fine,done valve adjustment and installed a new carb . Any one know why it might still be doing this ?

 

Could be a rip or hole in the intake boot. Or if its like the warriors there is a parking brake safety switch you bypass by just by fallowing the wires down from the perch. Unplug the 2 wires and plug them into eachother.

 

Thank you but I checked all that . Do you think its a valve ? And the air filter doesnt seal well either . i think it may be that

 

yes it could be only takes a hour to adjust them give it a try.

 

Do you now the valve lash setting ?

 

Ok I think yours is a 350CC so I looked in my books and for the Warrior and the Big Bear the clearance for valves when machine is cold and at TDC it is .06-.1 mm or(.00236-.00394 in) for the intake. Exhause it is.16-.20 mm or (.00630-.00787 in) I usually stay to the high side of the numbers.

 

I have had a warrior that did that too. Idle fine but not rev. I looked in the back of the carb and when I tried reving it up gas spit out the back of the carb. Now this is going to sound corny and like I'm full of **** but the problem was the stator was bad. So there is another thing to check.
