Before disturbing the carburetor, be certain that adequate fuel is reaching it.

A problem in the fuel delivery system is as least as likely as a problem within the carburetor. If the engine runs well when you add fuel to the carburetor, it suggests that the carburetor is working properly.

I believe it's possible to prime a vacuum tank with a pint or more of gasoline, which ought to be enough to run the engine for at least minute or so, assuming the carbureter inlet is not clogged.

I think typical vacuum tanks have a drain valve on them, which should allow checking for the presence of gasoline in the vacuum tank.

If debris in the gas tank or fuel line is causing your problem, the vacuum tank would probably malfuntion before the carburetor, and debris would probably end up in the vacuum tank rather than the carburetor.

Any air leak in the fuel line between the vacuum tank and the fuel will play havoc with performance, especially in hot weatther. A plugged fuel tank cap vent is another possible trouble spot.
