I think he is referring to an issue with the pilot jet.
I have an ATC110 that behaved similarly to what you are describing. I had to try multiply slide needle clip positions before It would start and run consistently.
Seems like mine ran better after lowering the needle (or raising the clip position).
Also having the foam filter on will make some difference.
Put your butt on the inside fender or end up on the ground!
