I was recently stranded when I turned a corner and my throttle stuck, causing the engine to rev up to 4000 rpm. I shut it down before any damage was done but once I towed it home, I found a 3" shaft 3/8" diameter connecting the two levers off the throttle linkage had a broken clip to hold in the ball joint. Does anyone know where that full shaft assembly can be purchased, or if the clips themselves are available for replacement? I saw a few other posts about problems with engine rpm climbing quickly so I'll pass this along to those threads too in case this was an issue for them, but any help on locating the part would be appreciated (pic attached).
