O Wise Collective, I seek thy wisdom:
The Previous Owner bought a carb kit, new petcock, some (Yamaha) tank rust neutralizer and various other parts. Problem was he never got around to installing any of it!
The tank sat with tape - blue masking tape - over the filler hole for seven (7) years. The tank contents are not a solid exactly, but a hard-shelled coating/mass of goo. I think it's starting to return to the shape of the prehistoric plants and animals from whence it came.

If I could get the contents of the carb bowl out in one piece, you could make jewellery out of it. Epoxy is hard once it sets, but this stuff is more like an amber ceramic. I had trouble scratching it with a file. I'm having nightmares imagining how it's clogged all the little float and jet holes.
![Shocked :shock:](./images/smilies/icon_eek.gif)
So I made a mixture of Gasoline, Sea Foam - the whole bottle - Adhesive Remover, and sprayed a half-can of Gumout carb cleaner into the tank for good measure. When I go out periodically to slosh it around, I can hear the sludge down in the bottom of the tank - Laughing at me. "ha-ha", it says, "You and your puny and impotent chemical solvents are no match for me!"

As for as the carb, the Service Manual makes it sound so simple. Just "Unscrew the throttle cable fitting and pull out the slide...." Are they kidding ?! I may not be the strongest guy in the world, but I'm no girlie-man either. I couldn't pull the throttle slide out of the carb - at all. Couldn't even budge it. That baby is epoxy/ceramic glued in thar. It's dangling in a jar of the same stuff that's in the tank. I'm hoping Tincture of Time will work its magic but losing faith fast.
One suggestion I got was something called Berryman's Chem Dip. - available at a nAPA store near you! Anyone know the chances of it working better than what I described above?
Thanks for reading.
