Please excuse me for butting in, but while we are on the topic of jetting ported 02 CRs I have a few questions.
I'm trying to get my 265 dialed in, and I've read Erics book on the ride and feel, but in there he states that "If the engine is slow to respond and bogs (engine makes a booooowah sound) then the carb jetting is too lean" and "If the carb jetting is too rich, then the engine will make a crackling sound..." I think that my jetting is too rich, but it bogs and "boooooowahs" (mostly going from 1/8 to WFO) indicating that it's lean. I only say I'm rich because other stock 02s in my area are running needles that are 3 steps leaner than mine. How would you describe the crackling sound that indicates a rich mixture? I would like to be picking up some jets and experimenting this weekend to try and get a little closer, but now I'm not sure if I sould buy leaner or richer. Sorry for the general jetting post.
