get a can of brake kleen with a thin red straw & shoot a 3 second blast into each idle screw mixture port. first count the # of turns to lightly seated before you remove em so you can easily return the screws to their original position(s). then get a high flow 10 micron filter in line right before the carb inlet to ward off a repeat
I'll give that a shot before I pull that Demon off. I did just fill the tank up to get ready for the Nationals. Maybe I rustled up some junk in the tank or pumped some in from the station and it got past the filter.
