OS 91 initial needle setting and type of fuel
 

First jet will be complete this week and somewhere in the process, OS paperwork has been lost. What should be the initial needle setting and what type of fuel produces the best performance? I figured that there is no one better to ask than the people in the field that have the experience.

Thanks for your help!

Start with the needle set 2.5 turns from close. Wildcat 5% jet fuel works well with OS-91.
