I've totally got my YS 63 out of whack. Can someone get me back on track with this engine? I just need me some needle settings to start with. I'm running Sig 10%nitro/20%oil fuel, Enya No.4 glow plug,APC 14X4W Prop. The time before last out flying the engine would run fine but after about 2 minutes in the air it would die. So yesterday I decided to get on the net and look up the stock needle settings and between that and my manual I closed the low end and backed it out 1 turn and turned the high end out 2.5 turns. Well this was so rich it was blowing raw fuel out the carb. So it would run but like crap. So I proceeded to keep backing out the low end to lean it up but never got it to run right. I also tried leaning and richening the high end but never got it running good.


Thanks,

Wrong fuel, wrong plug. It will never run properly with what you are using.

We recommend YS 20/20 fuel or 30% heli blend for the YS engines of all sizes.

Install a YS #4 or OS type F glow plug, they are both the same.

Go to www.ysperformance.com and follow the running instructions.

Good Luck!

Dave,

I can't thank you enough. I took your advise and bought some YS 20/20 fuel and a few OS Type F glow plugs. WOW!!! This engine came alive. I set the high end needle out 2 turns and the low end out 1.5 turns as per your instructions. Filled it with the YS blend fuel and she fired right up. All I had to do after she started was lean the high end a little and it was on. What a powerhouse. [sm=thumbup.gif]


Thanks Again,

Mike

COOL!

Have fun and good flying.
