OS 91 Surpass 4s - Which way is lean on LS screw
I just started my OS Surpass 91 that I got from a nice man on RCU. It started immediately and ran fine. What a pleasure compared to some experiences I have had. I am getting 9000 rpm on 14x6 Master Airscrew which will do fine for my 60 Stick. I didn't get any paper with the engine and my computer has a glitch that won't download the info on Tower. I would like to know if turning the low speed needle clockwise leans or enriches the engine. It idles pretty well but I suspect it is rich now.
