Yes I am running on muffs, and this is the first time run on muffs as ive previously started up (pre carb rebuild) in a bin full of water.
I think I will try it in a bin tonight and if its still high I will adjust the idle mixture slightly I know its 2 turns out whereas the manual suggests 1 1/4 out with 1/4 +/- from there.
