Thanks for the reply. The carb and selector will be serviced. What I
would like to know is if there's a solution that can be placed in the
tanks that will remove the residue. There is no fuel present in the
tanks, it all dried up probably years ago.

Okay gurus, this may be a simple one so here goes. I just bought a
project aeroplane and it's obvious the guy was using auto fuel in it.
It's been sitting for about 8 years and there's that great auto fuel
residue all in the tanks, selector valve (frozen), I'm sure in the
lines and I don't even want to think about the carb. Is there a way
to wash that stuff out without removing the sealant? I thought of
buying one of those cheap steamers from Harbor Freight. What are the
thoughts?
Thanks


You will have to disassemble some parts -- selector valve (which needs
some Fuel Lube anyhow), carburetor (look for corrosion), perhaps fuel
pump (corrosion, too).

The gum deposits occur when the fuel evaporates and should not be
present in the lines, although the old fuel will probably smell bad and
is good only for lighting fires. I doyubt that it would even work in a
lawnmower.
