metro engine

[rhys mate]

just wondering how to determine the year of my engine it a a 1275 metro engine. and are the subframes any different or do they slot straight in??

also what kind of power do they usually put out im getting mine dyno tested tomorrow and want to know if its normal or not.

cheers

The metro engine will be an a+ engine so 80s on in age but , the metro subframe is different and wont go near a mini shell
if that is what you are asking

[woody]

Post up the engine number and we may be able to help.

[just_st3v3n]

the 1275a+ metro's put out 72bhp standard, whether thats at the flywheel or not i dont know..
put up the engine numbers and you;l be able to find out who n what..

i managed 62 today but it was running very very rich so im expecting more the next time does anyone know how to tweak the HIF needle?? i cant find the adjustment at all

[The Marcos Graveyard]

You need to change the profile of the needle to "tweek" it.

The mixture adjustment is on the side of the carb.

[woody]

1275 A+ metro engines range from low compression metro vans to MG Metro Turbos with many inbetween. The first part of the engine number gives you the spec.

post that engine number already.. or if it a block like mine, the little plate has "rusted and fallen off, officer.. honest..."

its all here: http://joltfreak.tripod.com/id29.html

Just as a matter of interest, where did you get it dyno tested? What sort of cost is involved?

[CLUBMANGT]

Sounds like you need a go of the old gas meter mate

[rhys mate]

ill put up the number later haha

i got it done in CIT for free we had a Twin-cam and a type-r too!! some noise off the Civic.....

he said take it back after i find out how to change the mixture and see waht we get!!!

[The Marcos Graveyard]

The mixture screw is number 7 in the photo.

This is used to adjust the mixture at idle, the needle profile then determines the mixture further up the rev range.

thanks a million for the help! any ideas on which needle i should go for??

i got ny engine number 12H009157760!

thats not coming through as an engine number... 12H makes it a 1275, but after that,... can you verify that number?

[rhys mate]

ill double check with the number on the block thats what the log book says

[rhys mate]

i checked the engine number its no different to the one on the log book?? im confused!!

[keith]

id doesn't seem to be a mini engine, it might be a metro unit, or an allegro/maestro/other BL car. the "12H" makes it a 1275 transverse, prior to 1990, but you already figured that out!
see: http://members.home.nl/mmarx/mini/metronmbrs.htm

most likely so far is this: 12HD09 9.75 : 1 1989 1.3 Metro Saloon

[miniireland]

more than likely an early metro 1.3 hle

nice one thanks for all the help!! just need to figure out the needle profile now haha!! he thought the needle could do with being smaller or the carb being the original to sort the performance out!!

[The Marcos Graveyard]

The needle is tapered, It's the shape of it that alters the setting not the size of it.

There is a 3 letter code on the needle, which one are you running ?

[woody]

Engine No 12HD09,
I Found a listing of it as Mini 84-86 ,Austin 1.3L and 1.3 HLE.
To the best of my Knowlodge ther was no 1275 Mini 84-86 and I presume the Austin is referance to the Metro 1.3L and 1.3 HLE.
Dizzy number should be 42626

[mustard]

hle is defo a metro...

[rhys mate]

had a go off the carb the last day to try sort the mixture but when i did i noticed the choke had been adjusted to run all the time so i slackened it off and tweaked the screws a bit to get the revs up but the car kept hunting and cutting out!! it also got 11.5% Co2 in the nct so failed badly!! i wqs told to get a new needle and jet assembly so what profile needle would be best1!! must check the needle i have now!! its a 1275 metro im pretty sure its got a hif38 carb!!
thanks

is there a metal strip screwed to the carb body someplace with letters & numbers on it? usually three letters and four numbers. what does it say?

no matter *what* needle is fitted, it should be possible to get it to idle cleanly.

at bottom left hand side of the carb, as seen from the front of the engine, there is the recessed idle mixture adjustment screw. with the engine warmed up, timing correclty set and the choke fully in, turn the screw to get the smoothest idle.

i have an MG metro engine in my mini clubman, and the carb is HIF44.

thats the screw i was turning but i was finding it impossible to get it to idle!! which way do you screw it to reduce the mixture??
i got 11.53% vol and 2210 ppm!!! not good
