[AT] new to list

[Mike Sloane]

I would look for a pinhole leak in the intake manifold or at the head. 
Use an unlit propane torch, just crack the valve open, and move it 
slowly around the intake manifold and carburetor with the engine running 
at idle. When the propane gets sucked into the pinhole, the engine speed 
will pick up. Depending on the location of the hole, you might be able 
to patch it with JB Weld or similar.

There is not such a cradle of democracy upon the earth as
the Free Public Library, this republic of letters, where
neither rank, office, nor wealth receives the slightest
consideration. -Andrew Carnegie, industrialist (1835-1919)
