Obie, without a cattalytic converter, there is little you can do to reduce
this.  If the car originally came with a cat, and the WA emissions specs
were set for the car with the cat, you will have a great deal of trouble
achieving low enough CO emissions to pass.  Reinstall the cat, and you'll
see the CO emissions drop to nearly zero.  Highly advanced timing can raise
CO, so you may want to back off a bit and try again.  When the timing is
set correctly, on 87 octane fuel, the engine shouldn't ping.

Buy a degree wheel and a piston stop, and you can use them to find the
correct spot to place the pointer.
