ok, drove it last night late without changing initial timing, thought it was at 8btdc but after checking it , it was 4btdc, because I changed the cam timing. set it on 12btdc for next test drive. heck it ran pretty well on 4btdc, must be all the torque, its hard to tell minor tuning improvements by the seat of the pants power meter!!!
