The pinch test will tell you if your LSN is too rich or not.

1.Warm it up.
2.Go to full throttle for a few seconds to clear it out.
3.Go to idle and let it settle in.
4.After awhile pinch the delivery tube to stop all flow.

If the engine speeds up just before stopping, it's too rich. Adjust the LSN about 1/8 turn in. Start again at 2.

If it just suddenly stops with no speed up, it is too lean. Adjust the LSN about 1/8 turn out. Start again at 2.

It should barely speed up and stop when it's set perfectly. Don't sweat getting it perfect.
