W8Ye's correct, and this too is part of the learning process!

If this happens, back the LS needle out until it's flush with the carbureator body's surface. This yields a "ballpark" LS needle setting that will allow the engine once again to start and run.

Point I am trying to make here is that I think its better to screw up adjustments so bad that the engine wont run at all...THAN... have a flameout on takeoff. (Those really stink no matter how good of a pilot you are)

Experiment with (slight) adjustments, test then re adjust. Its half the fun IMO, and , your airplane and wallet with be very thankful!
