Review of engine:
This is my new experiance in YS engine,
this engine run smooth on the first run,
still in break in process, Smooth ideling
needle valve - High needle at 2 turn out
-low needle at 1.5 turn
2nd tank break in close 3 click from 2 turn high needle temp at 140 farenhite
then 3 tank close another 3 click making it 1.75 turn out
thank now close anther 2 click from 1.75 turn low needle close 0.25 making it 1.25 turn out
temperature at this settting is at 170 farenhite
Glow Plug Use is OS8 as recomended from manual for 30% nitro
Nitro is Morgan Fuel - cool power 30% nitro LS 20% oil
soo far break in for 4 tanks gonna finish and change the plug after 12 tanks
and settle tune at 1.5 turn on high needle anda 1 turn on low needle as most ppl recomend on the forum plus this engine get more power at rich side of tuning..
i ll put all review throgh time for the maximum performance
