OS SZH PS Oil all over the pump and base plate

[X]

OS 91 SZH PS is about 3 gallons through it. Lots of Oil all over the pump and base plate. Don't know where is the oil coming from. This engine got no power compare to same engine on my other Extreme. The setting are closed on mid and high is 3 click below 1 turn. The temp is around 155. Afraid to lean it out more even the temp is 155 F. Running Hatori muffer without any seal or gasket.

The one on Extreme is about 2 gallons, closed on mid, 1 turn on high and it got lots of power. The temp is around 210 F. No oil at the pump or base plate.
Thanks,

I am also haveing the same problem.

After a flight my Strauts backplate is soak in oil. What i notice is the regulator is spiting fuel out. So maybe during flight it spit more fuel.

But what cause it ????
