The perfect AFR is 14.7:1
He is talking about air/fuel ratio, not gas/oil ratio...lol...However that 16:1 gas/oil ration is way too much, better for you if you got some more gas and measure more gasoline into that mix to bring it to a 32:1 now rather than later...DAMIENI am running 16:1 -- I know I know... pretty thick... blah blah. I put a quart of 2 stroke oil in 5 gallons of gas. When that 5 gallons is up I will run 32:1.
