Hmm... I'm not familiar with the carburetor setup. It seems that everyone that works on them has some kind of fine tuning issue. Perhaps I'm wrong about that but it seems common. O2 sensor huh? You really think it would be causing such a lean condition??? Perhaps you are right and replacing it might be the best option.

I'm heading to Phoenix and will be in town on April 27th- 29th. Need a hand? I don't mind. I'll make sure to come by and visit with JohnnyB and JoseB. Perhaps we can all get together. I won't have my Raider though, I'll have a rental car.
