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,
