ks guys! I just got back from the field, using the OS needle had to open it 5.5 turns but its working fine. The only think I’m going to change is the fuel tubing, I’m using medium, I'll change them for large (I don't think is going to make any difference) just in case.
11cc ducted fan engines suck about 4oz per minute at full tilt, run fine with medium fuel tubing and can be richened to the point of blubbering. I don't think you need to change either.
