[Off in the Bushes]

I have a pile of jerry can in the garage and for the various fuel mixtures for the different 2 stroke motors and I want to reduce them to a few and use it in all my motors. The ice auger is a Jiffy and uses 24:1 and the chainsaw uses 50:1, and a snow blower that runs on 32:1. If one went to 40:1 is that to rich for the saw and snow blower? Thus if you went to 50:1 for the ice auger are you to lean for that motor and will you damage it.
What would you do?
