All,

Patient is a 2 month old Craftsman with a 4.5 HP Briggs and Straton
motor. Gas is fresh, oil is up to full mark. Mower has been working
OK. Last used about 1.5 weeks ago.

The mower will fire briefly if the primer dome is pushed. Then it
dies after using the gas supplied by the primer push.

I have tried taking the air filter off and have tried loosening the
gas cap (one thing at a time) with no change in results.

Seems as though it is not pulling gas after the initial firing. This
is a new mower with only one run speed. The carb seems bone simple.

Any ideas where to start?

Check and make sure you have not gotten a small pin hole in the primer bulb.
If this happens, it will do exactly what you are describing.
