had to smog my 85 today. Smog man failed it, said timing was off 10 degrees. suppose to be 6 btdc, says it is 4 atdc. In addition, CO (emissions) suppose to be .8 at 15mph and .6 at 25mph. Actual was, he says, 3. + on both. OK, went back and set timing to 6 btdc. locked down dist. drove back 2 miles to re-smog. Now smog man says timing is 6 Atdc, like I can't set timing. Here is the kicker, the emissions are now well in line at .03 at 15mph and similar at 25mph. So, at 10 degrees out of time emissions were way out of line, but at 12 degrees out of time emissions are way under the CO limits. Can any body out there familiar with CA smog stuff explain this to me? I think smog man is full of it. Will try again tomorrow.
