Another "safe" way to prime (which I read in a rc mag) is to pinch the line from tank to pipe, then pull the fuel cap open and let it snap shut a couple times.. You'll see the fuel run up the line to the carb.. I couldnt believe it worked myself, but it did.. (On a totally dry line/engine, that's sat for a few days, I still use the "blow" method though.. Just the fastest, easiest way imo.. Of course if ya have the hiccups or something ya might not want to put a fuel line in your mouth.. lol.. But give the "pinch and snap" prime a try!! </p>
