Convert 40:1 mix into 32:1 mix?

[Cujet]

As I always say, our testing indicated that 32 to 1 provided the best wear protection for normally loaded 2 stroke engines.

I have an '89 LawnBoy with many hours of running 40:1 mix. Still has "like new" compression and purrs like a kitten.
I'm 68 yrs old now and the "boy" is going to be mowing after I've given up pushing it.
I use the 40:1 in my LawnBoy and my Homelite trimmer.

I mix a rich 32:1 and use it all my 2 strokes, no issues yet
