I have a Michael Engineering Sticky Stuff
Dispenser. I bought it used in pretty good shape. I cleaned it up
and all, but I am having trouble with it. When I pull the plunger down, it
goes, but it does not go up easily. Do I need to unscrew the pump parts
where the cylinders are and soak those in acetone or denatured alcohol? I
bought new reservoirs, but what is included in the rebuild kits Aircraft Spruce
sells? Has anyone ever send one back to Michael to get it reman-ed or
should I just buy a new one? Thanks!
Will
