I have a problem with my badger 150. I used it this afternoon with no problems. I went to use later on the dullcote I am trying to spray and it is not feeding. The brush is clean and the dullcote is thinned, so what in the heck is wrong with it. I have tried everything that I know to clean it.

Make sure the air hole in the top of the siphon cap is clear. It's a small pin-hole, but if it's plugged, the brush won't be able to pull paint up the siphon tube.
