Re: Emissions rant.

Colorado has exemption for '75 and earlier, with a 5 year tag. My '83 Benz has to get snogged every year- opacity (soot) test. Blows clean every time, costs $55. The snot rag at the Airtest put my '97 Benz (gas engine, w/ traction control- not 4matic) on the regular roller tester, failed me because the rear brake were smoking! The ABS & TracControl did that, the pads got cooked. Official ruling, too bad- I should have told them it had to get put on the 4WD rollers! I pointed out that it's got all that info visible from the driver's seat, but to no avail. At least the trucks don't have that headache. I wouldn't mind the smog test, if competent personnel does the testing. I asked what qualifications the manager had, he said no ASE certifications, but he was authorised to run the machinery there. WTF? As to your carburettor emissions problem- make sure your float level is correct- it'll run rich enough to mess up the test. A fresh oil change helps, too.
