DO Not Play with the Throttle! Yet.
The Starter Motor does the "turning over". The engine "FIRES" a couple of strokes, because of accumulated fuel fumes.
Your cold start problem could be because of snug valve tappet clearances. Suggested by 11,000 miles and unknown maintenance history.
And can be exacerbated by opening the throttle TOO Early. But could be solely because of Your Procedure.
Try full enrichener, ZERO throttle, crank the starter motor 5-6 continuous rotations, if no start, Let go of the starter button! Count to 10, slowly. This allows raw fuel to vaporize, priming the engine.
Re-engage the starter motor for 5-6 more rotations. Hopefully it "fires" and runs on full enrichener on the 2nd stroke. If not, let go of the button for another 10 count.
Ok, re-engage starter button & on the second rotation just 'twitch' the throttle slightly open! Hopefully it is now running still on full enrichener. Let it run full on for a minute or two.
If the engine can only be started by opening the throttle to Amplify the cold cranking compression, that is an indication of Low COLD CRANKING Compression.
Usually due to snug valve tappets, due to mileage, hopefully not due to dirt thru the air intake.
Modify at "YOUR OWN RISK"!
