Now I read to bottom
, next time if this happens take the lid off and look
down into the carbs while its idling bad .
See if any one carb is dumping fuel into intake
So you can isolate which carb is goofy .


I cant envision exactly how this strap / check ball fell out
Of place.. i would suspect it fell out during disassembly.
But who know - i guess if that fell apart you might have been
sucking in extra fuel to idle circuit on center carb.

With todays crappy fuel and whoknows what in fuel tanks
and old lines - this is more common of needle seat issue .
But would have been nice to see how you stumbled across this
problem. I guess that would have been last place I would have
looked..
