Just started tuning a new 140 (sport) and it hits all the numbers but the needles seem a little off. I'm at 8200 (backed off a few clicks) on the high end and it idles at 2200. Transition is smooth and if it sits more than a minute or so, it loads up. I used the instructions on the YS Performance site to start. I'm using an OS F plug and 20/20 fuel. The tank is plumbed per YS recommendations and I am using a YS fuel filter. Here is the "seemingly" odd part, the high needle is one turn out, the regulator is 1.25 out and the idle is 1.25 out. "Out" meaning screwed full in. Any thoughts.
