I just put my 1970 TC 2000 through "Air Care" without
the machinations I had to do last year. The
acceptable HC is only 1036 ppm at idle while my
reading was 375 ppm.
Removed the carb covers, turned the jets to the level
flat of the bridge and turned each jet down 2 turns.
Checked the timing and adjusted it to about 3-4
degrees BTDC using the micrometer adjustment on the
distributor vacuum unit.
Readjusted the idle using the idle screw to about 1000
[I have a Gunson's CO Digital Meter]
Changed the jet needles (dropped the CO quite a bit)
Removed the crankcase breather pipe to each carb
(dropped the CO some)
Removed the air cleaner (dropped the CO some)
Detuned the car until it barely moved (leaned the
carbs - adjusted the timing)
