I thank everyone for their comments regarding the ignition system. I have ordered a new coil, cables, rotor, cap and plugs and will see if that improves things. I did notice a slight difference when I bypassed the J&S box (which is an early analog model) and the timing light showed about a 1-2 degree advance at idle when I removed it. A mechanic friend suggested I also check the catalytic converter too as it may be partially clogged. I'll let you know how it works out.
