Is there anything that can be added to the fuel to dissolve whatever keeps plugging my pilot jets? It only takes about 10 minutes for one to to get plugged up after I clean it, which gets annoying quick. Also it's the jet for the same cylinder that keeps getting plugged, could it just be something in the fuel line running to that carb? I took it off and tried to clean it out as much as I could but it didn't help.
