How to sort tune out on this engine

[DaveG28]

Ok had my first nitro run in nearly a year on Sunday and struggling to get the tune right on my OS speed.

Basically after playing I am now at the point where it:

1. Doesn't cut out at all, can idle and run etc no issues

2. At high speed is slightly rich (still some smoke on a long straight) but close to right, not far off at all

3. It has no low end pickup, it smokes and takes a long time to clear...the track basically had a slow half and fast half and was fine once it got uptisnpeed in the fast half, even at picking backup, but once well into the slow half lost all power and got eaten on the first fast straight before getting up to speed.

4. If I lean the hsn any more it no longer has any smoke at all on the straights

5. If I lean Lsn much more it holds on the throttle when I lift and idles high.

6. I am getting under 8 mins per tank!!


I am thinking I need to lean the lsn then reduce the idle...but always nervous about going lean!!

Anyone any suggestions!?
