i have a 94 400 automatic and the throttle gets stuck all the time. It usually gets the worst on full throttle and gets stuck and the only way to stop is turn the key off. i see the cable goes into some sort of cap but i didnt attempt to take the cap off cause im not real familar with atv's yet so i didnt wanna screw it up. what can i do? its not getting stuck on the throttle switch cause the lever comes back but its getting stuck on the carb or somewhere. any suggestions?
