Just realised, Bionic Beaver is 18.04 LTS, which I did try, but preferred the layout of Mint. Looks like you will have a couple more years of support.

When the first Electronic fuel injection Volvo was launched in 1970 the new cars being shunted around in the Ipswich Raeburn Road compound and then at dealers premises all having lots of short period cold running , the sumps would literally fill with pints of fuel , part of the PDI was to drain and add new oil .
I suppose there is more chance of bore wear if mixture is rich for a long time. Never owned a car with injection, had a couple of company cars that had it (I think) The Capri 2.0 Laser and a very late Cortina 2.0 GL

Those two Fords both used the Weber 32/36 DGAV carb, the only Capri with fuel injection was the Capri 2.8i using K-Jetronic injection. Even the Sierra (launched in 1982) took a while to gain fuel injection, if memory serves the first was the 2.0 GLSi and 2.0 Ghia i in about 1989/90 with the obvious exception of the XR4i that used the Capri 2.8i drivetrain.

I'm not including the Sierra RS Cosworth, that had EFi but wasn't really a mainstream model for most people.

I seem to recall seeing a messagea few months back when Bionic Beaver did an update that support would end in a couple of years. However i first started using LInux on the previous incarnation so i've already updated once to Bionic Beaver from whatever it was before - think it was the Yakkety Yak version but can't be sure.

Yes, got me thinking, looked at pics of Capris and Cortinas and they seemed to have carbs. Think auto choke though, perhaps this made me think it was injection. Never liked Cortinas, but this late one they had put a lot of stuff right, even the handling was not bad. The door locks were not up to much. Was in Brent X car park, did shopping and came out to car opened door and thought someone had stolen some of my belongings, was not my car I entered, was a similar red Cortina 2.0 GL. Quickly locked door and went over to mine!

Put a friend on Mint about 6 years ago and it has been pretty well trouble free. Just updated his PC to latest version as support for his ran out a while back.

Several 10 mile round trips, and trips to Aldi, 340 still running perfectly. Seems to be in better condition than me!

Good to hear such excellent news!

This is another one of those "make sure of your basics" threads, shows how much a basic setting wandering slightly off can cause a lot of grief!

Absolutely, but strange that it was fine for about 10 years, me checking with CO meter before each MOT. No adjustment needed.

The trouble was me b****ring up my CO meter by connecting it reverse polarity to the battery.

At least I have one CO meter working now, thanks to Laird Scooby.

About a year since I had the rough idle thing, can't believe it. Car has been going absolutely fine since then.

Yesterday was MOT time again, I was a bit worried, but it passed with no advisories.

CO reading = 0.94 %

Hydrocarbon = 40 ppm

I had to pay the ULEZ £12.50 daily charge to get to the MOT test station, but it was worth it.

But unfortunately, it looks like next year the ULEZ will expand into the area where I live, so I won't be able to use the 340 after that.

My 1962 Mini has been standing for something like 25 years, that will likely be tax, MOT and ULEZ exempt.

Last week I put some oil down the plug holes are tried to turn the engine, it felt stuck, but quite easily came free.

Next is to buy a new battery, rig up fuel and see if the engine runs.

The engine is a 1275 out of a Vanden Plas 1300.

that is a little weak for idle with a carburettor about 2% will give a smoother running on light throttle and better response when the choke is needed on a cold morning . ( max is 3.5% for MOT )

Thanks, I know it's a bit weak, but I wanted to be sure of am MOT pass. Last time I looked at the plugs (probably last year) they looked a good colour.

My friend's 1.4 340 went through the same garages MOT today, it passed, no advisories too. CO was 1.1% and the hydrocarbons a fair bit higher than mine, but still well within the limit.
