Is there a good upgrade for a Rochester B carburetor on an inline 235? I have about 1500 miles on the engine since rebuild, and the engine is bone stock except for hydraulic lifters.

I replaced the original carburetor with a rebuilt / refurbished unit from Kragen when I had the engine redone, and driveability seems to have suffered since then.

I seem to be running okay around town, but at at freeway speeds (60 - 70 mph) it feels like the carb leans out a bit and power tapers off. (I have more experience with Webers, so it could just be the feel / sound of the Rochester carb and I'm not familiar with it yet.)

Any ideas on where to start? I'm open to any options to shore up performance a bit. Is there a Rochester FAQ somewhere that I can check out?

Thanks!
