I have read numorus posts on this but do to co-19 can't seem to get the parts. Have a mec 9000 with metal baffle bar and bushings .Powder is coming out of bar on every stroke of handle? Have brass washers and rubber grommet installed. I have read good things about the plastic baffles but can't find one to buy. Any help or quick fixes out there? Should I just get rid of metal bafflel ?
