actually, I was fed up burning and sweating under the sunshine while working on the bike and didnt want to take the carb out and install back for each little tune on the screw. the first try was 1 turn off and I heard the back cylinder firing. so I just wrapped all and ran to the shadow...

I am pretty sure that this is not the best setting but no coughs, no hassling off the idle, both cylinders firing... how happier could I be? so I just thought that I could live with how it is after annoying one cylinder idling problem.
do you, glider, think that this idle increasing can be related with this wrong setting on idle mixture adjustment?
