this isnt what you would call a airboat post, but You guys seem very knowledgable with motors. Im trying to re-use a 40 motor and the carb is stuck. I've heared of soaking it in fuel or acetone. What would be the best method to refurbish the Carb and engine?

Soak it in denatured alchohol till it frees up. Then tear it down and clean it good and replace all O-rings.

Submerging in Marvel Mystery Oil is another good method. Let it sit in there until it frees up.

The marvel works well. to make it break lose in a hurry, submerge in the marvel in an old cooking pot, heat it to about 250 degrees for 20 or 30 miuntes. This will make the metal expand and let the oil soak into the parts. Do Not try and force it to free up.
Another thing to use is corrosionXworks wonders.

Thanks Guys, the problem is solved. [sm=thumbup.gif] Now I just need to get my hull built.
