My 110 seems to be running quiet well except after I taxi out to the runway and advance the throttle even a little, it quits requiring a restart. The transition from idle to full throttle is somewhat slow. I just switched to 30/23 fuel (from 20/20), made three flights over the weekend. The engine always died on final. Top end was strong. It did respond for a couple of missed approaches. Does the low end need to be leaned or richened?
Thanks, Carl

Not sure which way you need to adjust the low end....Is it loading up and quiting? If its loading up then you would need to lean the low end.

Leaning the low end mixture is "OUT" CCW on the air bleed screw on the throttle barrel.

The way to set the idle properly is to use a Tach and get it to idle at 2000rpm with your TX trim. Then when it hits 2000 rpm watch the tach for the first 20-30 secs If the engine slows down and quits its too rich. If it surges up and down then dies off its too lean.

If you adjust the air bleed idle adjustment screw out more than about 2.5-3 turns open from full closed you need to adjust the regulator screw. Lean the regulator a little say 1/4 turn and then go back and try your air bleed screw at about 1.5 turns open. The air bleed screw only fine tunes the idle mixture. The regulator has more to do with this setting and the transition.

The double check the reg setting. Set the engine RPM at 4000 with your TX stick. Watch the rpms with a tach. If it loads up and slows down its too rich, and if it surges up and down its too lean.
