I recently moved to Las Vegas. A smog test is required, even for classic car plates. The test consisted of two minutes at 2500 rpm, idle, 1000 rpm, idle, 2500 rpm, idle.

The car passed the 2500 rpm CO test of 2.50 with a 2.16. However, it failed the idle test with a 3.44. The tech stated it was idling too rich.

The car is a '76 912E with the 2.0. I installed a new K&N filter to maximize air flow. What else can I do to lower the idle CO reading?

There is a provision for a waiver, after $450 in repairs at an approved shop. I would like to put the money elsewhere.

Help?

Now there's some info that is useable!!!! Thanks.

Oh, I realize the K&N is not optimum, but it is to get the car through the test. The panel filter I removed was pretty funky, but it seems to be very effective.

I went back to the test station this afternoon and mentioned to the tech that I had noticed that the gas in Vegas is oxygenated, and the 912 still had St Louis gas in it. He recommended fresh gas, and also an oil change if it had not been done very recently, which it has not.

Now I have my weekend chores.
