Id go with CAB, and work on the jets/pv with all this six pack stuff going on ive been a little rich on my idle side, Ive had a 1.0 lesser PV and sure enough I went from possibly killing the family behind me with fumes to where it would take there sniffer stick to get me...well maybe not.

I dont know if most can get there center carb off as is but I got to start at the back and work forward.
