Has anyone used Hagen's Brew to clean up a dirty carb?  Any problems with seats and seals?  I would like to soak the whole carb but concerned it will deteriorate the plastic and rubber.  I always seem to have problems getting the brass jets and plugs out of the aluminum on the carb or I would just soak the pieces separate.  Any good ideas for preventing damage when disassembling?  With all this rain lately I really need the boat motor to run better than it has been lately!!  :^)  Might have to pull the planter with it on that last 10 acres of beans!
