I haven't messed with the advance much when starting, but I will try retarding the advance after it is warmed up.
I checked the tappet clearance at about 100 miles but not since.
It starts on the 4th to 7th kick when warm, fully advanced, throttle a little open.
When the motor was fresh (0 miles) I adjusted the carb toward the rich condition.
After starting it cold, I adjusted the needle about 3 turns out and then turned it in until the motor started to miss, then backed it out until I had no missing, but it seemed to idle to fast. So, I backed it out more and the idle settled down and no miss.
For a thousand miles it ran like that.
The signature of the motor has changed since then, it seems to idle slower and smoother.
Now I have it adjusted exactly like the book and the idle is fine and starts on second kick with no choke and no prime when cold.
When I prime it with two kicks, choke on full, then no choke and ignition on, It starts first/second kick (cold).
Now, 2 to 3 kicks with the no choke mostly full advance when warm.
I will try playing with the the advance and retard.
Went to the store and when i restarted while hot I retarded to 1/4 and she started on the first kick with a backfire.
Now I have a short on my horn. When I move the timing grip back and forth my horn beeps.
