I don't have any lack of power on short hills, but when I get a long uphill road the ATV will slow way down to about 30KPH. If I work the throttle to give it more gas it just gets worse. Then if I let up on the throttle it runs better, but of course slows down even more. Am I looking at a carb problem, or what? I tried getting at the air screw, but can barely get a screwdriver in it and then can't adjust...won't turn at all. I cannot find a fuel adjustment screw anywhere I can see on the carb, and the manual does not show one. My plug is burning black, wouldn't that be too much fuel, and how do I correct that? It may be that the engine is flooding when I go uphill and throttle up.
If my son goes up a hill this things seems to bog down and wont rev up. If i power brake it its will spin the wheels and start to dig a trench then loses power for a second or 2 then regains it etc. I would think it would keep at the power band or maybe not. I took off the pipe and ran it straight for a few minutes to test exhaust and it behaved basically the same. On a flat or semi flat it will do almost 32 and hold there forever but again go to the bottom of a hill on a logging road and start out not reved up it just wont rev up at all can damm near walk as fast up the hill. What should I be checking for?
