Re: Runaway throttle
Check for slop in the throttle linkage between the governor and the carb.

Re: Runaway throttle
Check all linkages from throttle control to the carb. Has the rod come loose between the left side rockshaft and the carb?

Re: Runaway throttle
Thanks, forgot to mention that when I do pull back on the throttle lever it w/slow back down temporarily, but then speeds back up when I release the pressure on the throttle lever. Really have to put pressure on to get it to slow down though. Dusty B

Re: Runaway throttle
Sounds like the governor is bad. Boss Hog probably nailed it. The weights are what bring the throttle down when the RPMs go up.
