Well almost had disaster yesterday - fuel pump gave out. I landed the plane due to lack of smoke in the air, and found DARK greay -> black residue on the bottom of the plane. Of course I pulled the pump and didn't fly again, new one will be here tomorrow.

The top of the piston is cola-colered; no scratches or discoloration below the ring or on the liner. Thank goodness for a ringed engine AND CASTOR oil!

Beyond that the 120 AX is purring like a beast and lugging the 9lb plane through loops like it doesn't even know it's happening

Other than that the plane and engine has me TOTALLY SPOILED! I flew the Dolphin today because of the bad pump, and YUCK! If I didn't still have payments to make on the new plane and engine I'd be buying a Venus 40 right now.
