I got off work a little early today so I ran home and watched a YouTube video on how to adjust timing and set it to 12° advanced. This made it idle much smoother.
Then I watched this video again and played around with my vacuum gauge. The choke wouldn't engage since it was fairly warm out.
I started at 3.5 turns out on both adjusters and it was about 18 inches of Hg. Backed them out another turn, revved it up some and no change to the vacuum. Backed them out another turn each, same deal. Backed them out 2 full turns, which is is the neighborhood of where they were in Denver, and still no change to idle speed, quality, or vacuum.
At this point, it was less responsive to blipping the throttle, like it'd kinda cough or stumble before revving up, so I backed them off 2 turns each. Throttle was fairly snappy. I was feeling proud.
Ran over to the Department of Environmental Quality emissions testing station before they closed.
They make you wait inside your rig while it idles, no dyno rollers like in Colorado. Never bothered to open the hood, just looked at the VIN and underneath with a mirror to confirm I have a cat. Then they made me hold it at an excessively high idle speed for the final test.
And I failed miserably. Really rich, so I'll start by backing out my adjuster screws some more until it starts to lean miss I guess? Need some advice.
Time for a cold snack.
