Replace the brass washer, it’s flattened and the tits aren't holding it in place, happened to me a few weeks ago…..
It will. Good luck on finding one, however.I have experienced the same problems in the past when using small flaked powders such as Titewad. I tried using the brass washer without much success. It’s still seem to migrate and block powder flow. I discovered that if I was to take double back tape and tape two together and also to the rubber grommet it stop the problem. The best solution is to purchase the red plastic powder baffle which is spring loaded . Do not use the black grommet with the baffle nor the brass washer . This will stop your problem .
