Hi guys,
I have been grappling with how to get a combination of large capacity engine, light weight and cheap fuel consumption. Generally speaking gas engines are more complicated, more expensive and heavier but cheaper to run. Conversely large glows are cheaper to buy, simpler, lighter but dearer to run.

Have you guys discussed or thought about adding needle bearings to a glow motor so it will run with a much lower oil content in the fuel mix? Say 40 or 50:1.
This would allow for a simple methanol/oil mix compatible with the existing engine's parts/fuel lines etc and would alleviate the need for plug conversions, presumably timing issues would not exist and there would be no need for 'exotic' fuel mixes.

I realize this solution would be limited to about 35 cc (the largest glow motors currently available). The Moki/Mark 2.10 springs to mind as an option.

Your thought would be appreciated [8D]
