Default DA-50 Hesitates, almost stops, but ..........

Got a DA-50 that hesitates when throttle is advanced quickly. It almost stops. If I bring it back right away it will recover, and stay running. If I advance it slowly, it seems to be alright.

Which needle do I turn, what direction, and how far ? ? ?

Thank you.

Sounds like your too lean on your low end. Try to richen your low end up a bit to achieve a smooth transition and good idle. If the idle is too rough then you have richened it up too much.

Low end tune to get a good idle and transition to mid-full throttle.
High end tune to get your max rpm's without it burbling in the air.

The DA 50 is fairly easy to work with IMHO.
