    Your 40:1 may be completely different than his 40:1. Same goes for 32:1 obviously. Randy doesn’t really have it tuned for anything other than his cutting conditions on the day he ran it. Every saw needs to be tuned when the weather, fuel, or elevation changes

    Se my chart in post #20. You would be on the nose at 40:1 if you add another half gallon of straight gasoline to the mixture and stir it in.

    There are many online calculators, you just have to be sure you enter the values correctly there are couple of links below

    However, I don’t think there are calculators that do the Calc the op wanted ( multi/serial Calc)
    But it’s simple enough if you know the amount of oil in the remaining fuel and you know where you need to get to. Ie more or less oil and then it’s simply adding more oil of fuel, as you can't subtract it.

    where I find difficulty is the imperial volumes, etc is so much easier in metric volumes.. but that’s how I learnt things in school..

    I just use a clear mini peanut butter jar. I scratched a line on 4oz. Works wonders
