I haven't ever flown when the weather was <70 degrees or so. I have a new OS .91 glow 4-stroke, and, before flying season, I decided to break it in. I can't get the thing to start. (I did all the tricks suggested in the engine manual.) The glow plug lights up, and fuel is getting to the cylinder. I've done the usual things--flood the engine, then crank it with the fuel line clamped, etc. It never even coughs.

My problem is that I have two new situations for me: never before used a 4-stroke, and this is the first time I've tried to start an engine when the temperature was in the 40's. I did not try a "hot" plug.


Suggestions? Maybe I'll just wait a couple of weeks until the temperature goes up. Then I'll have just one variable. Or is there something I'm missing with 4-strokes?

Thanks.
