I have returned home form the testing faciliyt this afternoon, and noticed that my NOx levels have risen, right after the carb was rebuilt. Here's the test results: HC: 281 (111 25 mph) CO: 2.26 (0.02 25 mph) NOx: 1980 (2318 25 mph) I have been through 4 emission tests - I am more concerned of getting a bootleg sticker or face a $200 fine if pulled over from the cops. If this is not over - I will be forced to retire the vehicle the the salvage yard or to another county which does not do emission testing; or donate the vehicle to the ArtCar Museum off Heights Blvd. in Houston, TX. for 2 years. Otherwise, I will pay $120 for a METRORail pass.
