my 89 blaster 240 is shooting fireballs out of the exhaust and it wont idle the carb was just rebuilt today and i changed the gas and put brand new gas in it. and the air filter isnt wet it was running fine last night until i went into a stream and crossed it and then it didnt want to idle anymore. then today after my dad played around with the screw on the carb and the screw on the tors it started shoot fireballs

whats wrong with this quad

thanks

Sounds like you need to get it tuned. If i was you i wouldnt mess with the screws unless you know what you are doing.

 

might of cracked your spark plug,,,,it might be loading up with gas because of a bad plug OR wire,and when it does fire,all of the gas that has loaded up is causing the flame thrower

just something to check

 

anouther thing you might want to check is if you just had the carb off to rebuild it,,,

A),,,you may not have the throttle cable installed correctly
B),,,you may have the throttle cable "twisted" if you rebuilt the carb with the cables still attatched,,,,if you rebuild a carb with the cables still attatched,its real easy to twist the cable by picking the carb up,setting it down while getting tools and such,,,,what this will do depends on which way it has been twisted,,,,one way the throttle will want to rev by itself,,,,the other way it wont rev all the way when you want it
C),,,same as A,B for the choke

 

Seen one that was running way too lean that shot fireballs & exhaust got redder than red hot!

 

ok well today i turned in the air fuel screw and pulled the choak and let it warm up for about 5 minutes and it stopped the backfiring completely now does anyone know how to fix the idle??
