Fuel siphoning will cost you time as you already know. To clear a bad flood quickly, pull the head, pinch off the line and crank the engine over. Some guys use a soda straw and blow into the intake, this is even faster. You either need to get in the habit of parking the model with the nose up, or use a line clamp after fueling. I can't say what exact amperage figure works best for your glow plug, you want to use the least amount of current that will do the job.
