Hi can anyone come up with any good ideas on what could be wrong with my fourtrak? Its a 1993 Fourtrak 2.8 TDX. The problem is that when driving & going at 2000 revs & above, the revs stay too high & takes a long while to drop to idle. Seems worse when the engine is warm. I've checked the cable thought it my be snagging but it isn't that. Any help would be much appreciated.
