I notice something else screwy... Today I was looking it over and I started it up cold, with the hood up. The sun was in the perfect position to illuminate the fuel lines and I saw quite a bit of entrained air in the fuel line going from the bottom of the pre-filter down to the injection pump. The bubbles were really moving through. What effect does this have on engine performance? I know it can't be good for it. Anyway, I guess I'll need to find that guy who sells Viton O-ring kits...

Another thing I noticed was that there was a significant buzz coming from the upper mount of the engine damper shock in the front of the engine. I could put my finger on it and it was really vibrating. Is there a replacement bushing for the shock? Also, after about 3 minutes of running, the buzz suddenly quit as if it was shut off by a switch. I don't know if it's just a resonance thing or what...
