Greetings Dave

I am a new YS user and am excited about trying some of these engines! I got my hands on a few from some club member to try out and had a few questions.

Is there a general guideline for needle settings? I am looking to get a misbehaving 110 working but the guy that gave it to me has really screwed the needles bad.

I would love to know a good starting point for needle settings and regulator position on the:

110
120
and the 140

These engines look impressive and I CANNOT wait to get them on some of my airplanes!

Thanks

matt
