RE: RE:
One to one and one half open is a poor starting setting as it will likely be too lean from the get go causing confusion.
If three turns works to start it then use three turns. Four turns is a possibility also After warm up open to full throttle and set your high speed as you would normally. Now if the engine will quite when you raise the nose to near vertical then open the needle a little at a time untill you can actually throttle the engine from near idle to full throttle.
An Alternative is rather than raise the airplane: open throttle to full power and let it run for a few seconds now pinch the carb feed line rapidly (just an instantainious pinch and let go) If you get a slight rise in rpm you are good, if you get stumbling then you are to rich and if you get an almost instant stoppage of the engine then you are too lean. Note this is for setting the high speed needle.
