Yesterday I took my G reg mk1b for its first MOT since 1996.

It's been in my garage for 17 years and me and my son have spent the last year, on and off, getting it running again.

I was expecting a few failure points but it sailed through on everything except emissions.
![](./images/smilies/spacer.gif)
It registered 8.46% CO against a limit of 3.50%.

HC was 515ppm against a limit of 1200ppm.

Idle speed and smoke tests both passed.

The guy who did the MOT said the results indicate that it's running too rich so I should check air filter and plug gaps as a starting point.

The filter's a bit dirty but doesn't look that bad to me.

Then again, since its been standing for so long, maybe it's deteriorated in some way and isn't letting enough air through.

I'm going to get a new one.

Plugs are a nice brown colour so, according the standard photos in my Haynes manual, no obvious signs of excess fuel there

I didn't check the gaps because I couldn't find my feeler gauge

but I'll get some new plugs regardless.

I had the injectors cleaned last year, so they should be ok.

Not sure if this is relevant, but one of the exhaust tailpipes had fallen off so I repaired it by using some jubilee clips to fix it to its neighbour and then used gun gum to seal the joint with the back box.

If that seal's not tight, could that affect the emissions reading? But if it was that bad, I guess it would have been an MOT failure.

Apologies for the rambling post

Any suggestions on what else I should check?

Thanks
