Emissions Bypass on a '79
Thought I'd pass along the results of my emissions test on my '79 that the PO had gutted the cat and disconnected the air pump:
Loaded (~30mph) HC 267ppm
Idle HC 71ppm
By the way, to bypass the air pump the PO installed a short belt (Browning 4L210) between the crank pulley and the fan pulley. There's no adjustment and you have to take the fan off to install, but it seems to work.
