A more serious rebuild involves removing lead plug and welch plug to
access and clean out passages using specified size number drills. Also
the very aggressive and toxic carburetor dip is a shop method.
Not many will want to get that serious. Usually spray and compressed air is
good enough.
The die cast zinc AJ series carburetor are sometimes corroded inside which
can plug or alter size of internal passages. Not much can be done about that.
It appears fuel is getting to the carburetor but not being vaporized.
The sure test is to swap in a KNOWN to be good carburetor
of correct type. KNOWN to be good is not same as ASSUMED to be good.
A friend had a small engine that would not start. He was a good mechanic who
knew his engines yet he could not get it to start UNTIL he replace the new
spark plug with one from an engine that would run. He had assumed a new
spark plug would be a good spark plug…usually but not always the case.

Tillotson AJ series has a screw at bottom of float chamber for draining fuel
and water as required or before storage. Curiously it is usually a 1/4" x 32tpi
super fine screw thread.Changed to 1/4"x 28 fine thread at
some point.
