Bill. I saw my first glow fuel ignition enginge Saturday. It was a converted O.S. 300 Twin. It really got my curiosity up. I started a thread a couple days back on the topic of ignition and glow fuel. Really interesting.

One thing that susprises me is the top end performance imporvement with it. What has turned up so far is that it imporves idle and slow speed and works best with FAI fuel. Quite different than your comments. I'm interested in hearing more. Oh yes, these were for a four stroke.
