truckernix has the right idea. I use the old suction bulb that was used for cleaning out my newborns throat as he came into the world. I've also used ketchup or mustard squeeze bottles. Either one of these work great to fill the carb. float chamber via the vent. Fill the float chamber once and it'll start and run. I've never had to reprime when using this method and it,s safe. If you have an engine that's sat a while without starting, I suggest pulling the fuel line, drop it in a can of 2 stroke mix and run a few minutes to lubricate the cylinder walls. Then you hook the line back up and run clean fuel.
