1994 LT-F4WDX K.Q. - Rebuild Advice

[superdude811]

im BRAND new to thew ATV world and i was given a free 1994 king quad. the thing is, the engine runs, but is verrryy rough. it starts fine, idles well, and revs fine too, but only for a while. then when given gas the engine bogs down and barely runs, puffs out lots of smoke and smells of oil and some times quits completely. then it will go back to running fine. and back and forth...the machine had been sitting in the guys yard for 2 years. also, gas is in the oil. i have no idea where it is coming from..

already i have taken the carb out and am in the process of rebuilding that..i also added a new air filter(the old one was black with oil and very chewd up)and spark plug(the old plug was black and charred as well.)

anything helps! THANK YOU

you're on the right track, probably all carb problems. gas in oil may be from bad needle and float if the petcock was left on or shot. running crappy and smoking from dirty carb and old gas. check the crank vent lines too going to the carb breather box. put a film of oil on your new air filter too. i'll look to see if i have a manual for your bike ....

When you change the oil and filter on those small Suzuki motors about 1/3 of a quart remains in the bottom of the crankcase. I was told you have to split the case to drain that last .3 qts. I think I came up with a better method. With a frame hoist or engine hoist or two big friends lift the front of the ATV up until the bike is vertical. That remaining oil will drain out the filler hole. Be sure to shut the fuel petcock before doing it or gas will run out the top of the carb because you are unseating the neeedle valve. Mine had water in the oil and I changed it 3 times, but it still remained grey. After lifting it once the oil was clean.
