Another opinion:
Before starting, take a "squeeze bottle" (empty mustard or ketchup bottle), wash well, and fill with gasoline. Use the squeeze spout to fill the carburetor through the bowl vent.
Why?
(1) Easier on the starting motor.
(2) May prevent future carburetor issues. Tests have shown that a mechanical fuel pump diaphragm under no load will flex approximately 0.030 more than under load. If the fuel pump has been on for some time, there may be "varnish" build-up on the diaphragm that will flake off due to the additional flex, and flow forward to the carburetor.
