Earnest,

 

If it is the first time I am starting my engine, I set the mixture at full rich, give it about 2-3 primer shots, and it kicks off after only a couple of blades.  If I don’t do the primer shots, I get a response like you did.  You didn’t mention if you used primer shots???  As the engine warms up, I reduce the mixture gradually back to the center mark at idle.

 

Don’t go overboard on the primer shots.  You will flood the engine.

This portion from the datalog is where it kicked off and ran.
