Thanks for all your replies. I've taken many "progress photos" and I intend to post some once I learn how to do it.
This is my current problem and I'm hoping someone has experience with this: I soaked my carburetor and petcock in Berryman Dip-It cleaner and, while it removed all traces of fuel deposits, it left a "calcium-like" deposit. Does anyone have an idea of what's happening and how to remove it other than with a wire wheel/brush?
UPDATE: I just held the lower part of the petcock up to the light and there's a pinhole where the largest deposit was. I checked the other parts and there's also a pinhole in the carburetor fuel bowl. Now I have two ruined parts that'll only delay my project. Can't find them on ebay; does anyone have these parts available for me to purchase?
