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

Go to the instructions at www.ysperformance.com and set the engine accordingly.

If the regulators have been fooled with, set them with the top of the brass screw flush with the edge of the casting. That will be your starting point.
