Tom I'm gonna call this morning I'll let you know what they say. I did take a look at it last night once it cooled down. It's only that one spot coming back from no air where it pushes and binds, seems like a slider handle that rides with the air control would be a better idea vs the lever, but I guess harder to keep air tight. It really amazes me that something so simple can cause such problems. I have a lot of slop where that slider goes. What kind of grease did you use and where can i pick some up?
