Help with HIGH engine RPMs

Sounds like you need a better penetrating fluid. WD40 helps sometimes, but there are products out there that do a much better job of soaking into and freeing up stuck parts. Check it out at just about any auto parts place or Canadian Tire.

Its possible that it is already set to provide all the possible slack (and stuck there) .... how does the throttle slack adjuster work? If it is already at its "loosest" point...I will have to see if I can jury rig it.

Hey there Trapper,

After you loosen the little lock nut, then first try turning the large adjusting nut/cylinder so that it would be unscrewing OFF of the threaded shaft, and see if you can get it to turn and come off!?
It may be severely rusted inside, or the P.O. may have loosened it and the put it back on and possibly cross threaded it!? If you can get it loose and off, then you can possibly spray your WD40, or some better penetrating oil into it, then try rethreading it back onto the threaded shaft. Inspect the threaded shaft to see if the threads have gotten damaged as well. The further out on the threaded shaft the large nut is unscrewed, the LESS slack there will be in the cable, and vice versa, so to get more slack, you will need to turn it down onto the threaded shaft a bit!

If all this fails, then you'll just need to spring for a new cable, easily acquired from several sources online, or even locally....but probably much more $$.
