No, sorry.
When tuning nitro engines people refer to needle adjustments in "hours". Basically, envision the needle like a clock face and only make 1 hour adjustments at a time. However, in your case you should go a little more, like about 3 or so I would guess. So if when looking at the slot on the needle it's straight up and down (pointing to 12 & 6 on a clock), unscrew it until it's pointing to about 9 & 3. I hope that makes more sence and isn't too confusing.
