Re: gas oil ratio
well i started off at 16:1 and im using 20:1 now and will use 24:1 later.
and i never had no smoke coming out of my muffler.
but at 16:1 i had a drop of oil drop out of muffler after turning engine off.
at 20:1 no oil comes out of muffler after turning off,only while running - atleast it keeps my chains and under frame oiled up nicely.
