Bing mixture when fuel is poor - question
I have arrived in Tajikistan, filled up with fuel and my R80 G/S is suddenly running rough at low revs, and running very rich (sparks coked up and you can smell the fuel). Pinking, I assume, having never encountered it before.
Tiffany has confirmed that the fuel is especially poor in Tajikistan and that one must grin and bear it. She also suggested a question here. So I was wondering if it's worth adjusting the mixture screw out 1/4 a turn or so, or is it better to leave it as is, given how sensitive Bing carbs are?
Otherwise, I imagine it's just a case of taking it easy on the throttle, which I do anyway.
