When I restored my Tiger I found the fuel lines plugged with dirt and other junk from the old gasoline.
I took a piece of weed eater string and chucked one end in my electric drilll. I then started to feed the other end into the gas lines while running the drill motor at a medium speed. The weed eater string cleaned out the lines without damaging the inside of them, and was flexible enough to make it around corners and bends in the lines.
Yes, but you still need to “blow” the line out with compressed air, I don’t really see the purpose of all that additional work? If one can’t blow all the junk out with compressed air, one usually replaces the line with a new one? Right?
