I am sitting in the kitchen going over what can go wrong. MOT for 2 oclock today, spent an hour trying to get the washers unblocked.
I kept finding a substance that looks like black silicone sealant at the jets.
I seem to recall assembling the pump many years ago and using it for some reason.
The car is running well and I will ask him to check the emissions for me as it is nice to know how it is running.
Regards Kels.

There is no compulsory emissions test for these cars in the UK?

There is no compulsory emissions test for these cars in the UK? It is part of the MOT but very relaxed for older cars. Basically unless there is thick black smoke on gentle throttle an older car will pass.  |

Ah, we have 3.5% CO as a limit for all car younger then 7/69.
Not that this poses a problem...

Hope all went well:-)
They don't care about CO for older cars here. However, I want to know what it says. Around 3% when I took it to the Norwegian MOT recently. They usually praise the crab at the test, they are especially impressed by the brakes. I too enjoy its brakes, even compared to modern cars. They feel safe in all conditions.
BTW I took my old Scania LS 81 lorry to the MOT yesterday, and it passed with no comments at all:-) I'm very pleased with it. These lorries are extremely reliable and strong, they are jokingly regarded as ever lasting and impossible to kill:-) In five years a light bulb has been the only thing it has needed:-) Except, greasing, oil and diesel of course.. And it's used quite a lot. Pity it has to go to the test annually (vehicles above 3,5 tonnes) and the test costs more than £ 200..
Regards, Tommy

I realise that emissions are not checked on our cars in the U.K. I asked because I wanted toknow if the car was perceived as running weak or rich.
It drove down pretty well to the garage about 12 miles, he came out to the reception area and told me it was running a little rich.
Unfortunately he tried to weaken it, when it began to run badly he says he returned it back to the old setting.
Oh by the way she passed, he remarked the car was in good order and he found the brakes very good.
On the way home she ran alright but seemed a bit hesitant while steady running.
I am beginning to wonder if the new thermostat I recently fitted is opening too early . What stat are you all using? The temperature gauge still seems to be sitting a bit low.
regards Kels

Hi Kels Happy to hear your car got the MOT it's always a worry even when you know it's all OK. I used to have the same experience in Leeds, the garage would weaken the mixture at the MOT and then it wouldn't run properly, so I got into the habit of weakening it a couple of flats before I took it in. Is your temperature guage now showing a lower reading than before you changed the stat? Do you know what temperature it has stamped on it? By the way, your status is showing up as "Guest" on your last post but as "Member" in the earlier ones. Not sure I understand that quirk, maybe Richard can have a look?

Standard thermostat for an 1800 is stated as 82 degrees Celsius.
Try checking your mixture by using the lifting pin on the float side of the carburettor. If idle drops it's too weak, it should rise and then fall. If idle rises and stays there, it's too rich.
While driving, pull the choke out gradually, to see if the hesitation goes away/ if it runs better. If so, your mixture setting could be too weak.
Regards, Tommy

Hi, I am pleased to have passed the MOT.
I had problems, see post (misfire) I started having difficulty after having the head machined to run unleaded.
I removed the temperature sensor as it looked vulnerable.
When I replaced the head I also relaced the thermostat.(tested in a pan of boiling water it seemed a good one).
When I started the car the temperature gauge stayed at the bottom of its range. Well it must have resented being removed and replaced.
Tony Wood supplied a replacement. The gauge began to read but much lower than before. There was some doubt as to whether Mk1 cars had a different sender, mine had a lucar spade terminal.
The car kept hunting at steady speed, accelerating hard it was better.
Eventually it dawned on me that maybe it was really running cold.
I replaced the stat with one from my local factor.It may have been an MG part No.
I am now wondering if the new stat is incorrect?
Looks like a phone call to Tony is required.
I have just changed my service provider from AOL to BT, would that explain why I have become a guest?
Yes the car runs better with the choke pulled out.
Regards Kels.

Hi Kels I think I have discovered why you were showing as a "Guest" - it is possible to post without registering - I am responding without signing on. Do we think this is a good idea? Maybe you need to calibrate your temperature sender - measure the resistance at the specified temperature(s). I will try and find them if you have a problem. I assume your fuel guage is reading correctly, if not then this could indicate a problem with the bi-metallic voltage regulator for the instruments. Regards David Hi, I am pleased to have passed the MOT. Tony Wood supplied a replacement. The gauge began to read but much lower than before.
