I run super in everything
I do also but I also run a lead substitute or a valve saver product. When those engines were designed they were build around leaded gasoline. Unless they have had an overhaul update with new valve seats, etc. I would suggest a lead substitute.

High 89+ octane with no ethanol would be ideal but the non-ethanol isn't available everywhere. We try to run 93 octane in most of our stuff along with seafoam additive.

87 octane and a cap full of Marvel Mystery Oil here. I suspect the compression ratio isn't very high in my old motors.

For the last year I have been using 100 octane aviation gas, (Ethanol free) in everything I own and I don't ever have any carb issues anymore. All my Kohlers seem to really like the Avgas. I don't remember if it's leaded or not, will check on next file up.
