Various carbureted small outboards. Can some persons here share with me how to do vacuum test at the carburetor. I have had too many issues where I have a good spark and compression and sometimes a questionable carburetor . Other times I have run into bad seals in the leaf valves. I would like to know which method , tool or contraption I can rig to get a vacuum reading prehaps at the carb throat. Thank you.

Vacuum gauges were always hooked up to a fitting on the intake manifold of a motor. Good luck in finding one on an outboard. Let us know what happens.
