There is an old version and new version of the Michael's Sticky Stuff
dispenser. I would recommend disassembling the pump including the
pistons. Then, call Michael's and tell them what you've got. When I
talked to them they were very helpful and willing to explain what to do to clean
mine up, but it was helpful to have it apart to be able to describe its
condition.

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
