I am done my engine test stand and bought some 2 stroke low ash oil and am just waiting on my prop hub to get here. I know this engine fuel was mixed 40:1 when it was in the weed eater. So I will just mix it the same for now.
There was quite a bit of buildup in the muffler and I figure the manufacturer is always going to lean toward a rich mix when fuel/oil mixing is concerned.
I have read about guys going to a 50:1 or even 100:1 mix when running these engines.
Thoughts ???????
