OS 50 SXH Hyper not burnng all the fuel

[Kingy97]

Hi
I'm hoping you can help a newbie?
I have the OS 50 SXH Hyper on Vision 50 Comp, still on my first gallon of fuel but Ive noticed that there is a large amount of fuel coming out of the exhaust...by large amount I'd say 5-10ml per tank of fuel. The mixture screw adjustments arent enough to reduce this although it does gain head speed at a good rate, doesnt get bogged down and hovers well...plenty of smoke
At idle, it does sound a little raspy but it starts first time everytime
Im using an Align outrage muffler and 20% optifuel, No8 plug so am a little confused as to why how much fuel is passing straight through...any ideas what could be going on inside?
Thanks for looking

It's possibly the oil - not the fuel

Thanks Jafa
...as in I have too much in my optifuel 20% so its just going straight through or that I dont have enough so the engine isnt doing what its supposed to be doing.
Thanks again

The fuel I use is 24% oil. My heli has oil all over it after a few tanks.

The oil is in the fuel simply to deliver lubrication to moving parts
The fuel burns - the oil does not - most of the oil comes out of the exhaust as vapor and collects where it lands
This is entirely normal for two stroke engines
