When people ask me what's wrong with their computers, I sometimes say, "well, there's this nut that holds the keyboard? there's your problem" and then I hustle away before the meaning sinks in.
So maybe some karma is coming back to hit me. My BX24 has a problem, and darned if it isn't "the Nut that holds the throttle". But how to fix it right?
The BX24's a year old, and the problem just started now. When you let go of the hand throttle lever, the engine throttle spring pulls the throttle lever back up, and the RPMs go down, all the way to idle. Not enough friction. So I took off the housing and it was obvious that the nut on the throttle lever was loose. But after tightening it to the point where the throttle was pretty stiff, it quickly works loose again -- the action of the throttle is like ratchet wrench on it.
I found a second nut lying on the floormat in there, so I thought maybe the two nuts should be tightened against each other, but that doesn't provide enough resistance to self-loosening either. I'm wondering if another part was in there that was lost. Assembly order: the throttle shaft, which goes through a chassis mount, then two stacked cup washers, then a flat washer, then the nut (and maybe 2nd nut). Can anybody look at theirs and see if there are other parts in that stack, and what order they go?
Thanks in advance!
