Pe,

If you read my post carefully you will see that the brass clunk is used only as a weight on the fill line in the tank, and that I do in fact use a felt filter on the feed line to the carb.

Pat,

I was hoping for a more indepth response from you.

So far no one has addressed my only concern, which is simply what are the possibilities as to what might have caused the goo on the clunk and on the sides of the tank.
