A better title might be California SMOG Inspection Black.
I’ve procrastinated getting to it. A recall of the last near miss.
M<Y 83 and it’s 94 LT1 are running just fine according to the seat of my pants.
I took the precautionary run on the freeway awith as much throttle as I dared. It was a lively as ever.
Went to the last station that passed my Jeep just fine. But the on that I had an issue with over a “snap throttle” test.
It did not work. And, true enough, on revving and backing off it did indeed smoke from both pipes. Black particulates. Against the shop['s advice, I asked they continue the test. Two of the techs admired the installation. The tech on the machine, not so much ,just did the hookup and the visual and the two dyno runs.
I was asked to open the gas caps! That needed exam was done by pressing the spring loaded diaphram and noting that they were lined.
Well, as I expected, the numericals and the visuals were in compliance. But for the black smoke, it passed. But, because of the smoke, it was marked a fail. ,
Why does it smoke.
It is carbon loaded. I’ve not done much freeway run ning at speed, almost all put/put around town. Run it long and hard AKA blow out the carbon. The “smoke” is not really the black denoting an overly rich mixture, but carbon loosened along the
entire system and being cleared out. Induced by the pre test run by me on the freeway.
It is an overly rich mixture. Sticky injectors. Add some Chevron Techronic in a rich mix to the fuel and drive it a lot in a "spirted fashion. D2 in lieu of D1. To get the rpm’s up.
Objective "cleanse the injectors.
Remove the injectors and have them serviced. S.D. Faircloth in FLA. Long time lister here and good guy. cloth
Complication; Registration due by 10-22!!! Best, fi before, fall back, go on non op and get dispensations to run for short times.
