Running it last fall on the 8x4 prop and commercial fuel, I easily got 12,000 RPM. Today with the same prop, the same contra and needle settings, I got a sputtering 6,500 tops. Maybe I should bite the bullet for the commercial fuel and use my own mix for wood-stove fire starter? Or, should I try goosing my mix with more ether or Amsoil?

Either way, this KMD is a lovely little engine and I'm willing to figure things out to keep it happy! Thanks.
