my king quad isn't running good it's a 1998 lt-f4wd with a300cc .
It bogs out after it has run for a minute, like the plug is fouled.
I repaced the plug added some dry gas and carb cleaner but it still has not helped.
would any one have any ideal or would have had a simular problem?
any help greatly appriciated, thanks Dave

 

i have a 1992 king and it had the same problem we took the carb off and checked the needle make sure the float is sealing the needle completely if it is try tightning the jet of the out side of the carb
it is on the bottem and toward the front when you tighten this it will up your idle so just unscrew the idle nnob until it sounds right may take two or three time but that was my problem
any questions just lemme know
hope i helped

 

Fuel supply problem. Check the tank vent (take off the cap and blow thru the hose on top), the petcock and its screens (see if putting it on reserve makes it run properly), the fuel lines, the fuel pump, the carb body for plugged passages, needle and seat.

 

thanks i will pull the carb and check it out. also the valve and lines look good.
What will be the easiest way to take the carb of. does the air box have to be removed ?
thanks dave

 

just loosen the clamps and work it up and out. Don't forget the fuel pump for potential trouble. diaphragm pump mounted between the front frame uprights.
