My wife's rod and reel went for a prolonged swim in the surf a couple of days ago. So I dismantled, cleaned etc and while reassembling I decided to investigate a problem which it has had for a long time. That is the age old issue of bail-arms not self returning when winding the reel.

Anyway, examining the mechanism that is supposed to trip the bail-arm It seems somewhat badly designed. See photos below.

Bail-arm in closed position:


Bail-arm in open position:


Bail-arm release rod (the on inside the spring) that is supposed to ride the ramp on the cam and roll the bail-arm elbow around, actually bends before doing so.
I have dismantled both of the bailarm elbows to look for obstructions, but it all seems normal to me.
The rod in the spring has a small pin which locates into a hole in the cast alloy elbow and that seems to fit just fine.
