Well, its July 4th, and its been pouring rain for days in Texas.....no flying. Cant get my OS91 started to test fly this used YAF-16A that I picked up.

I put an arrow to the air mixture valve to ask a question....from the closed position and the body adjustment sitting at 90deg, how many rounds out do I need to start at? Im assuming this is just like the high end needle? New to DF engines so any thing helps!

thanks and have a great 4th of July!
