OC-3 Throttle Control

[Nick C.]

The throttle on my OC-3 jumps down to low idle when I'm plowing along and bounce on a furrow.  The teeth on the throttle guide plate are good (not worn down) although the throttle lever inside spring could be lubed a bit.  Is it a spring problem that make the lever jump off it's ratcheted position?

The little pawl needs to be ground to an angle, about 90 degrees and that should take care of the problem if the spring is good.

My OC3 has a friction type throttle control; two plates with spring through which bolt goes, tighten or loosen to get proper tension, hold throttle where you want it. I didn't know the type described was on an OC3. Anyone know which type was OEM?

Thanks Ray!  I'll give that a try.
