Ted, what kind of grease were you using for the cylinder arbor lube? I have been using Mobil 1 Synthetic grease and it seems to hold down the fouling. I know it isn't PC, but if it works.....Does anyone have any thoughts on how often the old timers had to stop and clean that arbor, or what they used to lube it? Maybe they just never took their guns out to the range for extended sessions?
