I have had my carb get pluged up on a few rare occations. Here is what I do, get a larger fuel line that will connect to your fuel bottle and with fuel in the bottle connect the bottle to your carb and just squeeze the fuel throw the carb. I have a inline fuel filter so its every easy for me to just disconnect the line at the filter and connect my fuel hose to it. My fuel hose is connected right to my bottle at all times with two zip ties and I just put the small rubber cap on the end of the line when I am done, this way if I ever get that clog or need to prime its very quick and easy to do.
