have a sportsman 400, it cuts out going up inclines. Have replaced fuel filter,spark plug,air filter, pcv valve, checked spark arrestor, gas cap. Seems to be a fuel pickup problem like maybe the float in the carb, or something in the tank. Just wondering if anyone has experienced this or may have suggestions.

 

I would cheak for dirt in the tank and maybe clean the carb and check the carbs float heights. Cant be the tank vent line or it would stall even on flat ground,I would think.

 

you may need to readjust your float in the carb.
