Last week, after the heavy snow finally melted, I took out the recently rebuilt GTV18 pictured in my avatar to do some work in the field. All went well, until I had to crank up the throttle to get through some heavy mud. Unfortunately, when I did, the throttle stuck wide open. I first checked the throttle cable, but no problem there.
I next wondered whether the governor might've stuck. I tried to adjust the governor three times (loosen the nut on the arm, hold it to open throttle, and twist the governor clockwise while facing forward, then re-tighten). But, that didn't fix it.
Any suggestions from the pros here? It has an opposed twin Briggs. After all the work that went into rebuilding this thing, it's killing not to be able to use it.
