Hi Tim,

It's two parts of high test gasoline to one part of 10% oil, 10% nitro glow fuel. The trick is finding the glow fuel, even though all the major manufacturers make it. It's often called Glow Fuel for Large Super Tiger Engines. The Echo 23.6cc seems to run particularly nice on it. In very few cases, one needs to raise the lever in the fuel regulator just a touch to increase fuel flow. Other than that, you just open the needles about a half turn or so more than normal, and then fine tune as normal. The engine will like the idle mix a touch richer than we normally set the gassers.

Funny you should mention the twin. I built it some time ago, and it runs great. But just a couple of days ago I pulled the Gas/Glow Poulan 42cc off my Giant Stik and installed the twin. Test flight as soon as I can get around to it..... Man, that engine runs as smooth as glass. If you set a glass of "liquid refreshment" on the test stand with it running, it doesn't even shake the beer... whoops, I mean liquid. I also have it set up on Gas/Glow.
