Newby to the T3. Got an 81 with 1600 CT engine. Just failed MOT on, amongst other things, emissions.
12 months and about 6000 miles ago Co was 0.11% and hc 159ppm It's now Co 0.6% but the HC 2472 ppm. It's a standard engine, car, ignition setup. Bus runs fine. Any clues what might be the cause of this huge jump and how it could be remedied?. Many thanks. |

Start with the basics, remove sparky's are they all the same colour or just one black for example.
If so which cylinder. Check breather hoses, air filter, engine oil - does it smell of petrol. Check float level in carb, sometimes the float develops a leak and lets more fuel through. Let us know what if anything you find. |

Had the bus stood still for any length of time before the test?

Been used daily. Gonna have a good look tomorrow ready for retest Tuesday. Did find one of the air filter vacuum hoses disconnected so hopeful it's a lean burn misfire issue. Will update once I know more. Thanks all.
