Good evening all:
New to JD Forum, but am on Wheel Horse Forum. Have gotten great feedback for my Horse, thought I could get some direction for my dad's F932 in here. The problem is simple, but is pain to figure out. This happens all the time and there is no set pattern as to why it is happening. It will not throttle up when the lever is pushed forward. If you throttle up and down eventually it will throttle up and runs fine. It has nothing to do with allowing it to warm up, it can run for an hour, idle it down, then throttle it back up again, and it will not respond. The entire carb has been removed, jets cleaned, bowl has new seals. Intake seals are fine coming from head to the carb. Linkage is nice and tight. Springs all appear to be correct size and function as they should. Here is the kicker. When you throttle it up, the gas will fill up in the bowl, but will not flow over into the intake to the heads. It would seem that maybe there is a bypass we are not aware of or????? Need help. Other than this little(pesky) issue, the F932 runs outstanding. Only 1600hrs. on the Yanmar 28hp. gas engine.
