i disagree TOTALLY with rcken. YES glow fuel can be ignited by a spark. even a static discharge will set it off.

i own a "gasser" that was giving me all sorts of problems......so converted it to run methanol. i did nothing more than make an adaptor to use a glow plug in the spark plug hole and retuned it. the engine is 45cc in an 84" extra 300.....works VERY well
