EE 3 accelerator pump

Put a rebuild kit from Classic & Exotic in my EE 3 carburetor. The old accelerator pump had disintegrated to almost nothing from our modern gasoline. The new pump fits in OK, but doesn't move and down as freely as the old one. This is the type with the round spring behind a leather disc. I put a very light film of oil on the accelerator pump cylinder in the carb housing to lubricate it for the leather pump. Is it normal for these accelerator pumps to be a little stiff right at first when installing them, and that they need to be broken in a bit?
