Hi plasticmaster, if you can get some methanol try to mix one part methanol with 2 parts 15%nitro glow fuel this should give you a 10% nnitro mixture as for oil if its on a 18% oil content you'll probably end up in the 12% range so probably your mixture will be a 10/12 glow fuel which once you mix with 2 parts gasoline it will give you a 3.3% nitro and a 4% oil content, so go ahead and make a samll batch and try it on your 42 poulan as Gas/Glow mix with an OS 4F plug.

A 1 to1 mix of 15% glow fuel with methanol will give you a 7.5% nitro and 9% oil glow fuel that you can alsomix with 2 parts high octane gasoline and at the end you will have a 2.5% nitro and 3% oil which isn't bad for Gas/Glo fuel either.
