Hmm.. it makes sense too. Higher engine temperature, so less compresson require to ignite the thing.

I feel so ignorant (I guess like many of us ) as what we are doing here is absolutely unique. Racing car guys use methanol, gas and nitro, buy they don't deal with the glow plug - they use spark ignition. RC guys deal with methanol and nitro on glow, but nobody is adding a gasoline to that thing. And RC engines area a little different talking about compression. On the top of that every weed whacker/blower/chainsaw motor is different and never intended to run on glow fuel.

So I guess my only option is to ask questions, share with results, and experiment till the head blows off
