I have a lot of hours flying this setup with numerous different engines. It uses a mix of 1/3 glow fuel to 2/3's gas. This provides enough methanol for a reliable catalytic reaction with the OS four stroke glow plug we used. Very reliable operation with easy starting, a very low idle speed, and a noticeable power gain. Interesting that OS jumped on the Gas/Glow "bandwagon". I too wonder what the difference is with their GG glow plug.
