FWIW, I just checked mine (at last!) and they are H 2-1/4 turns and L 1-5/8 turns, and it is running and idling well with the 18x10PN, 87 octane w/Pennzoil 40:1.
Maybe a little rich, but not much. Can oil type/ratio affect this?
It potentially can but shouldn't be much. The oil content we use is from about 1% to 2 1/2%. Not a whole lot of difference there to make much of a difference. That;s my guess anyway. Ed has much much more experience with gas than me and he may have a little different take on it

Another factor I forgot to mention... I first tuned it with ambient air temperature of 10-12 degF, which means relatively dense air. Next time I flew it, it was about 35 degF.
I haven't flown or run the engine again since then... still holding at about 2/3 gallon of fuel through it thus far.
Come on, spring!
