RE: Converting a 4S glow to gasoline and oil only
Why not try Gas-Glow?
A lot of people are having great success.
1 part glow fuel 2 parts gas.
Keep the oil content the same because of the bearings.
You may need to add oil to the mix to keep the oil raito at 20%.
It works well on 2 cycle conversion engines using 10/10 glow fuel.
Just a thought.
