RE: GAS/GLOW HOW TO....
Sorry your formula should not have enough methanol to keep a glow plug lit.
There is a gas-line antifreeze called HEET, you want the stuff in the yellow bottle, not the red bottle.
It's basicly 12 ounces of Methanol.
You can use this stuff to make small batches of gas-glow fuel.
It works well for test batches.
I have found that glow fuel like 10-18 or 15-18 will work as gas-glow fuel.
But that is getting close to the upper limits. And it won't work in all applications.
Perhaps if you mixed your glow fuel with equil parts of HEET and then mixed it with gas, that would be a lot closer to what you need.
If you are useing it in a used low compression engine it may be pretty close.
The extra oil would help engine seal and the extra Nitro. would make up for lower compression, it's worth a try.
