I am having a lot of trouble with a GS Storm buggy. It starts fine and idles ok, but you have to open the throttle up all the way to get the thing to even roll. Does it need a tune, or is it just worn out? I checked out the driveshafts and diffs on the buggy; they were fine; I checked the shoes on the motor and they looked ok but I am having a serious problem.

Please let me know what you think. Come on smart guys! Let's hear it!

Thank you.
