You can run it on either one. You’re safe at 16:1 because the original specification is 1/2 pint of oil per gallon of gasoline, which is what equates to 16:1. I run mine about that or even a little richer @ 12:1, I use Amsoil synthetic which evidence suggests means I can run it leaner if I wanted to, but as a rule I never run any of my antiques any leaner than 20:1. Some Lockwood and Elto models have to be as rich as 8:1 and sometimes I even mix up some 6:1 fuel, depending on what kind of mood I happen to be in that day.

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
