Do you not know how to reset governor

This sounds like the carb is plugged. Sometimes fuel thickens and makes globs...

If you verified the fuel flow to the inlet of the carb, then you need to take the carb off and open it up....
So, what needs to happen is you blow out all of the passageways with carb cleaner.

Any adjustable jets: make note of the position it is in, and FINGER TIGHT turn it clockwise until it closes (typically 1 to 1 1/2 turns) SOOOOO, you can set this jet back to the same positon....when finished blowing everything out, bottom the jet and back out the number of turns out, noted for that jet.

Open the float chamber, and clean as necessary, Inspect the float adjustment: invert the carb, and observe the angle of the float, relative to the carb body.... Usually almost parallel, but not necessarily.
Inspect the inlet valve, and clean those areas...

I usually use all new gaskets and valves, but if you are not a carb person, cleaning is effective and I think old gaskets may be okay, if not torn or damaged.

sounds like you are on the right track, I would replace the needle and seat and also check the roll over solenoid that is on bottum of float bowl, some times they go bad and do that. and they have also had issues with needle and seat not sealing,. some people have put shut off valves on their line and turn it off when not using hope this helps you, don't forget the thumbs up!
