Change the garage you use for MOT to start with - mine would adjust the emissions and re-test it.

I heard that dodgy garages don't warm the car up for long enough to make older cars fail and then try and buy the failures cheap, as they say it's too expensive to fix. Doesn't really apply to minis, but even so.

It’s not particularly dodgy garage as it was just a kwik fit as I’ve only just moved to the area (Cheltenham) and was unsure on where to go, it passed the one half of the emissions but failed on the co part of it, I’m guessing I just need to turn the fuel mixture down?

Kwik Fit = dodgy, as Cal says, change garage! My local Kwik Fit kept failing my rear brakes on my Mk1, as their machine was too sensitive, I took it to a local independent and it has passed every year since.

Yea, kwik-fit are not suitable for our little cars. I needed a quick tracking check last year and the guy failed to even get the machine on to my 12s.

Is this your Spi motor running a HIF? Was the test done engine specific or car specific? I'm not 100% but do they do it off engine number? So the car is older and would have a higher CO limit but the engine is newer and has lower limits for an ECU controlled fuel injection

It is a spi with a hif44 on it yes, the limit was 3.5 I think, so unsure if that’s the limit for the engine or the car, but I assume it’s the car, I’m hoping I would just be able to turn it down to lean it out and take it back and hopefully that will make to clear

It’s a 1275cc spi engine with a hiff44 on it in a 1989 car, the co limit was 3.5 and the car was getting 6.5 on the results

Owners manual for my SPI says 0.5% max (hot) at tailpipe. That's the manufacturer though, not the ministry.

Okay but my car is a 1989 so I assume it’s being tested to 3.5 which is the car not the engine

Will be tested on the age of the car in your case. Assuming the cars well maintained eg clean air filter etc then just adjust the carb. Long time since I've adjusted an HIF but there should be an adjustment screw in the side of the carb body. If it's never been adjusted (unlikely)it may have a blanking plug covering it that needs digging out first.
