RE: OS .40 engine
I don't have an elec starter either -- suggesting for starting with chickenstick.
Glo starter off engine, throttle wide open, finger/thumb over carb, rotate prop 15-20 times with other hand (good to have glove on and hold onto prop as you rotate it, don't flip it), keep thumb/finger over carb, throttle to idle, throttle trim at starting point (about half trim), glo starter on engine, now remove finger/thumb from carb and use chicken stick to flip prop right away--key here is keeping finger/thumb over carb until you get glo starter on and ready to flip prop. Otherwise, the fuel will drain back out of the fuel line.
