I picked up a mint 04 WR450 that sat for almost 2 years. I had to flush the tank, petcock and carb. Problem is that I can't get all the crud out of the fuel tube that is inserted in the carb that the fuel line attachs to. I have had to pull the carb apart 3 times because crap keeps getting into the seat and causes the gas to overflow. What can I push thru the tube to clean it out that is flexable enough yet strong enough to get out the crud?????
