High needle all the way in still rich

Post a pic and I'll let you know if the lever is at the correct level. You don't want it set too low.

I really don't want to take it back apart it is the first time I have got it to tune close to the suggested 1 turn out. Right now it is a 3/4 before it had to be at a 16th to 1/8 and throttle was still a wee sluggish. It is about 2 paper thickness below dish.

I do have another question the high needle still has to be turned completely in. Now I am tuning with only a 20" bar running 50:1 dolmar synthetic oil with 91 octane no ethanol gas.
So now my theory is this saw was made when fuel was mixed at 16:1 and 32:1. Is it possible the mix is too thin with the new synthetic oil at 50:1 causing the needle to have to be seated and run high side only through the bypass?
When I start milling I will be running 32:1 with a 36" bar. I didn't want to mix separate fuel right now without having some projects inline.

Hopefully bar oil isn't seeping into the crankcase.

Whaaat can that happen? Is there any easy way to check that.

I suppose you'd check case pressure with the oil tank cap off.

On occasion with a faulty carb, I flood the saw, seat H&L, start saw and choke till dry. Sometimes this will remove an obstruction.
