I have some questions getting this dialed in properly. I think I got it pretty close and it seems to be doing OK but I was wondering does the pinch test still work for tuning on this carb? I pinched mine and it almost immediately shut off. I'm use to the factory where it took like 3sec. Is that normal with os? I got it brand new and had to adjust it some to get it started now it's running good I think although a few times it's just shut off on me but I think it just need some more fine tuning. Does anyone know what's a recommended setting on the os like factory setting to start with?? Thanks
