Took my 74 SB into the Delaware DMV for inspection, and failed the emission test. It already has new plugs, coil, air filter and new cab. Engine was recently rebuilt as well. Don't see any vacuum leaks. So, other than trying to adjust the idle are and lean out the fuel mixture, plus recheck the timing .... another thoughts? ( the failure was high carbon monoxide ... CO and or Hydrocarbon failure) |

Gross failure, or did you just miss by a few points? _________________ 1968 Beetle (storage)

Not sure ... They list three headings;
Readings ... (Blank)
Limits ....... 600 for HC and 6.0 for CO
Results ......Both state "Bypass) |

The 74 SB should have an EGR system. Is yours installed? I think the law states that emissions components must be present. |

I'm glad in New York, cars older than 25 years are exempt from emissions testing. Safety inspection only. _________________ Glenn

Glenn, I live in VA, and we also have a 25 year exception for emission I believe. Having said that, I was told by an inspector once that the exception was that my car didn't have to pass the tests, however all emissions related components needed to be on the car for a visual inspection. Even that may have changed over the years.
I cant speak to what DE does, I was just curious if this could be why the OP had his fail. |

CO is usually carb related and hydrocarbon is usually ignition related . How long since tune up and oil change . Do they check for missing emission parts . Make sure the dwell and timing are right on and idle is on low side and oil is changed. Can you get a picture of engine compartment. Egr is oxides of nitrogen check . Good luck |

Texas used to be the same way. Folks would drive to the next county over and have it inspected there to avoid the emission part of the inspection.
25 year limit here as well. _________________ www.vwnos.com [email protected]

Wa state doesn’t do emissions after 25 years, and no safety inspections for anyone. As long as the state gets their money they don’t care what kind of death trap you drive. To be fair I’ve probably driven vehicles in the past that wouldn’t pass a safety inspection. _________________ 69 Beetle - Daily driver

Did they give you a printout of the numbers. HC, CO, NOx, O2?
The actual numbers would be great info to have, unless you maxed out their machine.
My guess is you need a good tune up, as already mentioned. While you got the plugs out and after a valve adjust, do a compression test. _________________ Jimbo

Rebuilt engines often need valve adjustment after short time of running. Had that several times.
If an exhaust valve doesn't fully close this will lead to high CO and HC values.
Otherwise if a cylinder does not fully work (e.g. due to bad ignition) also CO and HC values rise. HC always means unburnt gasoline.
I would not expect a missing EGR to result in high CO and HC. _________________ AC:

thanks for all your input ... the engine is just rebuilt with no time on it. I'll check out the items posted ... timing, compression, mixture and let you know how it went. And right, all the DMV did was an idle check as required. Any more thoughts are appreciated. |

Thanks .... other than making the other checks, I’ll put some more time on the engine break in. |

High HCs, especially at idle, are usually ignition issues (bad plug wire or connector) CO, well sometimes even a half a turn on the carburetor's idle mixture screw can make a huge difference in that number. _________________ Andy T.
