Hi again Bushy260,
I don't really want to go to anything other than 50:1 fuel mix. The suzuki 2 stroke uses that. The chainsaw used to use that (an MS180 also stolen.) The blower was a Masters 909 40:1 mix and while decent enough was pain to manage different fuel mixes. I was making up 5 litres at a time and everything could use it. Only stihl oil used. I probably could have gotten away with 50:1 and that oil in the blower, admittedly.
