is this fuel consumption normal?!

[roblee]

i dunno about your sweet lil pride and joys but i just calculated that my 1.3 mayfair does 20 miles to the gallon! is that normal and if it isnt does anyone know any ajustments to reduce the thirst.

good lord no! my cooper with a dellorto 45 still does nearly 30mpg, where do you start? blocked air filter, choke stuck on, worn carb, binding brakes, incorrect tyre pressures, mixture or timing incorrectly adjusted, leaky fuel tank... the list goes on..
Maybe start with a good service, rebuild the carb next or at least get the mixture checked, i think a 1.3 in good order should be doing nearly 40 to the gallon.. sorry, this is all assuming its a carb engine!

[Simon1275mpi]

Great scot! I'm with Paul, do a service. The carb may of also been fiddled with for an MOT?

I would expect 35-40mpg driven economically.

[roblee]

yes it is a carb and the garage did fiddle it for the mot. you guys assume too well. ill have a lil play at the weekend to see if i get get a lil ecconomy from her. im a student so it would kill my bank account if she stays this pricy.

if u only do short journeys this seems about right as the majority of the time the choke will be out

[Simon1275mpi]

What's a choke? Game-boy Mini's (Injection/ECU) rule.

You should only need the choke to get your car going and progressively reduce to closed as the car water temperature rises. Pulling out your choke to hang up your burberry baseball cap, will leave you with 20mph Stephen ;D ;D ;D

I've recently be reintroduced into the cheap man's carb tuning. Dig out the Haynes manual and it identifies the mixture adjustment. Follow the instructions and it will be near spot on for economy and performance. It worked for me last Month.

But if that fails... like mine , I've traced it to the carb float jet not sealing, flooding the carb and running the car way to rich!!

?
WTF?

U still have a choke with a late mini u just dont need to pull a cable

[Stephen]

oh and a colortune should do the job better on a standard mini or rather, make the job easier than a haynes manual

[Simon1275mpi]

Whatever! ;D ;D ;D ;D ;D ;D

I was/wasnt impressed with the colour tune. Once I've sort Josies carb rebuild, I'll have another try with it. If found playing with the mixture and listening to the change in idle, when lifting the pot a millimeter, much faster.

Actually I dont have a coke, I've a ECU that adjusts the fuel, rpm idle and ignition to suit the engines water/air inlet temperature and air inlet pressure. Amazing thing ;D ;D ;D ;D

[oldgit]

TILL IT GOES WRONG THAT IS ;D ;D ;D ;D ;D ;D ;D

i was always led to beleive that a choke was only needed for staring purposes and that it should not be used after a few short minutes.

my proper mini with a carb only needed choke to start first thing in morning and by the time i was at the end of my short road it was no longer needed. but saying that mine was set up by a perfectionist lol.

who needs sensors and stuff, when all you need is a decent screwdriver and a good ear to tell you whats wrong.

Long live Mechanics! Down with Vechial Technicians!

lol loads of smileys would of been here but used quick reply hehe

My injection systems SPI & MPI have not failed me (touch wood).

But when a wrong component was installed, problems incurred. I'm sure i'm put the wrong coil or needle in the carb you'd have the same problem

Gameboy mini's, the reliable alternative. ;D ;D

[Miniböttcher]

you have done it now

jinks

some of us with carbs (rule) just adjust them at home , but with a ecu you have you get out you wallet and hope its big,

and you can tune a carb a series more

CARBS ALL THE WAY!!!!!!!

LOL HA HA HA

[Simon1275mpi]

Arh, wrong yet again. The ecu is self tuning all the time for best performance and economy unto 80-85bhp. ;D

Admittedly to get from 85+ does entail a premium of about £800.

Pleased your sorted.

My Dad is looking at buying a diesel Saab estate. Saab is owned by General Motors . So the Saab has a 150bhp Diesel Vauxhall engine which is extremely good ,my friend at work tells me . He was technician with Vauxhall since he left school before working with me . He gave me the technical handout he recieved when he went to the Vauxhall factory for the coarse on this engine . I had look through it at the weekend .
This engine has 16 sensors and I think it was 10 actuators . The electronic control module (ECM) is situated behind the front bumper and in front of the wheel .
So providing no-one crashes into it when it is parked crushing the ECM, to get it going I would of thought a either a carb , distributor , coil and a set of points is going to be less agro and cheaper to replace than one of 16 sensors or 10 actuators if they go wrong .
Ok the sensors help the planet by making sure the engine runs correctly and to its full pottential to help lower and eliminate harmfull emmisions.
SO
Why do the manufactures do all this clean stuff and then have a dirty great polutting 5 litre V10 engined 4x4 in there range or a V8, V12 petrol/ diesel saloon or 4X4 model .
Look for yourselves , Audi/VW have all the above alone , most mainstream manufacturers have 4x4's and or similar vehicles in there model ranges .
No wonder the b.uggers cost so much to tax .
Deservedly so .

Sober as a judge before you ask Si ;D
