RE: Hand cranking
Hand starting a cold 4 stroke glow engine is a chore. 2 strokes are generally easier, as 1 revolution transfers fuel/air to the cylinder, compresses and ignites it. If a person just turns thru the first revolution and a half (the breathing strokes) on a 4 stroke, then triest to start it by driving it thru compression, well there's nothing to light....
If the glow plug is accessible, a couple drops of glow fuel in there may help.... Then at least there's something to burn! Otherwise, it will take several QUICK revolutions (no starter applied) to wet'er up a bit, then try to hand prop it (with a chicken stick, of course....)
