Hi Everyone.
My sons Mk2 Austin Metro A+ 1000cc has been running great for 2 years now but it has been running odd on occasions over the last 3 months and today it has given up. It went into Elgin which is about 15 miles away with no problems, after about 5 miles on the return journey it died, it then restarted and went about 250 yards and died again. I then got the help me phone call. It done the same for me, went about 300 yards and died. Turn the engine completely off for a few minutes and you can repeat the cycle again. It just looses power, the engine is running but it splutters a bit but keeps running. Turn it off for a few minutes and start it up again and you can drive it up through the gears for a few hundred yards and it then looses power again. It is as if the fuel filter gets clogged up with something and starves the engine of fuel, then when the engine is off the filter clears up a bit, until you start the engine up again and start driving again. Does any one have any experience of this or have any ideas what might be causing it. If it is the filter, where does it sit. The tank is half full with Shell unleaded petrol, the Power Spark electronic ignition distributor cap looks good and the rotary arm, Lucas sport coil is less than 2 years old, NGK plugs and Lumenition leads are about 2000 miles old, carb dash pot is topped up regularly with oil. Thanks in advance for any advice you can offer us.
Kind Regards
Tom

Location: Jelling, Denmark | the only filter it has as standard is a very small one inside the carburetor. I have three suggestions:
- check that the mechanical fuel pump on the back of the engine works, the diaphragm inside can collapse. maybe its is not delivering enough fuel, try travelling for a distance as very low revs to see if it will go further this way.
- take the carburettor apart and check if everything is all-right, renew that which isn't.
- the air pipe where air gets into the fuel tank when fuel is sucked out is placed behind the filler flap and goes down to a small pipe on the filler neck check that it isn't clogged. |

Location: Near Elgin, NE Scotland | Thanks for the reply. I think the exhaust is ok, or at least it sounds ok. It was a brand new full Powerflow system about 4 years ago and has done about 6000 to 7000 miles since then. |

Location: Near Elgin, NE Scotland | Hi again
Sorry for the late reply, new parts took a while to arrive, (well, sort of)
Took the carb to bits and found more crappy bits in the lower section than I would have expected to see. Took the fuel pump off and it seemed to work, it pumped the fuel each time I pushed to lever, etc. The fuel filter is part of the pump and I found a fair bit of crap in the carb, so for the sake of £35 for a brand new fuel pump I decided just to buy a new pump and eliminate it from the possibilities list. I also bought a new vacuum pipe that goes from the carb to the distributor as the original one has started to disintegrate at the elbow section where it goes onto the carb, plus I was not convinced that I was able to blow through it clearly. Everything else appeared to be ok. So the parts arrived about a week ago but no one thought to tell me they had, so I finally fitted the new parts on Wednesday evening and drove it about for 10 minutes or so and another 5 minutes or so tonight and all seems ok so far. My missus has agreed to leave the Soarer at home tomorrow and take the Metro into Elgin for a longer test run as I will be working close by in case in dies again. Will give you an update at the weekend.
Thanks for your advice so far though, it is greatly appreciated
Kind Regards
Tom
