[dil1986]

hi
im kinda new here well not done many post
i am wondering if any1 on here has any ideas were i can ger my carburetor sorted at im not mechanically minded i am from the westmidlands ive been told its a m10 engine its a 83 model 316.
or would it be better to get a setter of webbers on there any ideas please let me knw much appreciate it

[DanThe]

83 model? You need to get some pics up

Is it still the standard carb or has it been replaced with a manual choke type?

[town325i]

will get sum pics up there is some pics on here of the car from when my freind had it ill post his name on here 4 u

[dil1986]

as far as i know its a standard carb

[Fushion_Julz]

The standard carb. on the early E30s (and E21s and '02s) is a pile of shite...causes no end of problems.
If it's dead, use the opportunity to upgrade to a Weber...IIRC the 28/36 DCD or 38/38 DCD are direct replacements, other than the manual choke (that requires a cable running to the cabin and the mounting of the choke pull-knob). I think the manifold on the E30 is ready for these to mount on directly.

This will improve your fuel consumption and the performance...

thanks 4 the help i dont have to pull a nob so i take it its not a maual choke
any suggestions of where to look 4 them and to get them fitted ?

[E30BeemerLad]

how much are the webber aftermarked carbs worth?

[dil1986]

i have no idea hw much or were to get them from

[E30BeemerLad]

I have one which I may sell, but want to know how much they are actually worth as I have no idea. I'm guessing anywhere between £50-£100

You can get a weber replcement carb, you can buy them new for £200 or usually pop up used for around £20-£40, you may get slightly better Preformance and MPG.

you could go with ITB's

Depending on your budget

the standard 316 carb is a dreadful thing and once it becomes troublesome your best throwing it away.

A set of twin 40's will set you back about £500ish all in (including manifolds) if you look carefully enough. A 32/36 weber downdraught needs an adaptor to fit onto the M10 manifold and is supposed to offer a 7% improvement over std. I have one here, on a M10 manifold, though it needs an adaptor also, it's one I made up just to check that the engine was good on an old car I had.

[dil1986]

are u sellin ? e30 bemmerlad please let me know as im intrested ty

I changed my 316's Pierburg 2BE carb (the one you currently have) for a direct replacement weber - This was a manual choke one and fitted straight in from the box - I bought a brand new one for approx £230 and spent £40 in labour getting it fitted by a BMW specialist up here.
The difference in the car was very noticable - better sound, better power and better mpg. I would 100% recommend getting this done as it transformed my old 316.
I got the new weber on ebay - here is a link to one for sale right now from the chaps I bought mine from:

I loved that car - why did I ever sell it!!!!

[dil1986]

are u selling lanc n were cud i get the manifold from will the garage who can fited 4 me do the conversion do u knw

[dil1986]

thanks 4 that chemical al
im just checkin it out looks promising
ta
if it makes it sound betta should go well with my stainless steel exhaust sytem

[Alex]

You want a set of twin 40's sounds awsome

I think that you're better doing it this way - especially if you are mechanically incompetent and have no mates that know old cars inside out (Like me) - Buying the carb new and getting it fitted professionally means that your are much more unlikely to have problems in the future - You just have to swallow the fact that it'll cost you close to £300 to do.
For hassle/worry free driving, i'd happily pay £300, but that's just me...........

Best of luck with whatever you decide to do - A lovely running 316 on a weber is a delight - 95-100hp on a car that weighs around 900kg is nippy enough to have fun in, and they look the dogs in that chrome!

[dil1986]

yh i wud have it professionally fited and i wud love a set of twins but all comes to price
ill post sum pics up of the project

[dil1986]

hers a link of my freind who had the car originally b4 he sold it to a melon of a m8 who i brought it off but all pics are on this thread

is it better to have a manual choke? my m10 doesnt have a manual one but it does struggle to start sometimes when its cold or been left for a few days

[dil1986]

thats a gd question jay ?
any1 got a answer ?

[Fushion_Julz]

Nothing wrong with an auto choke, per se, but when it doesn't work (or stops working) you'll be cursing the lack of choke control.
Even worse if it jams closed...your engine won't like running that rich for very long!

Personally, I'd prefer no choke and carry a can of easy-start for those cold mornings instead.

It isn't the choke, though, that is the main issue...the standard pierburg carb is a hateful bit of metal...converting to manual choke isn't going to improve it or the behaviour of your engine...

The M10 is a fine piece of quality engineering let down by the carb and the distributor...
Replace the carb and service/replace the distributor and your car will benefit in both performance and economy.

is the webber carb the best to go for? the ones ive seen only seem to have manual chokes

Webers are THE benchmark for traditional carbs - either as original equipment on some cars or as a direct replacement when the factory stuff fails.

A manual choke is preferable to an Auto choke as theres less to go wrong and you have full control over how long the choke stays on for. Once auto chokes start to wear/get old they can stick on for far longer than necessary causing your car to drink fuel.

Dead easy to fit a discreet manual choke conversion to a previous auto-choke fitted car.

Carbs......proper old-skool

thanks for the info rob, might consider doing that, as you say you can control the choke yourself which seems better to me.
Would an automatic choke cause any probs with the idle of a car as when my cars warmed up it idles poorly, feels like its gonna cut out then kicks in and revs up then drops down again.

[martauto]

How do they rate on an auto ?

Mart.

[lance1a]

Rigging a manual choke is easy, and at least you know it will work. It also requires less plumbing than a water operated one.
There are other options but Weber is about the best choice. Jets and service parts are easy to come by.

An auto choke can cause problems with idling if either it sticks on meaning the car will run very rich, or if it cuts out too early meaning on cold mornings the car doesn't receive enough fuel/receives too much cold air whilst warming up.

If the car idles poorly once its actually warmed up it could be just that the carb is fecked anyway - leacky vaccum hoses around the carb or the carb/manifold gasket could be another cause of poor idle if the carb itself if OK.

I have a car coming in with the m10 engine in its all been rebuilt at great cost and it has a good weber on it too,

[DanThe]

Carbs are crap, id rather change the engine for a later fuel injection one than buy a new carb!
2 litre Ford carbs are supposed to be a good upgrade for a 316

[capri_rob]

haven't owned a car with a carb since 1994 .......just a lot of fuel injected turds....

[dil1986]

hi can any1 help
i cum across sum webbers but dont knw if they wud go on my e30 316

Bit of a big generalisation, there...Carbs are good if you don't want to run any sort of electronics...also good for racing engines since they are good at flowing high volumes of air with single choke per cylinder at a low cost.
Single point injection systems aren't as good, overall (for power and ease of tuning), as weber 40/45 DCOEs, for example.

Of course injection on ITBs or slide throttles is better than carbs, but it also carries a weight penalty and requires some form of metering electronics.
