That's right bring it down to a personal level calver, always the same with some people...........

Frog I beg to differ also, my 1380 can return 42 to the gallon if driven steadily. I fitted my first dcoe in 1984 and every mini I have owned since has had a weber fitted. Infact even the MG Metro I owned briefly had the HIF swapped for a 28/36 (before anyone points it out, yes I know a 28/36DCD is a different carb to the dcoe range).

[Nightrain]

Does anyone see a pattern here?

LOL that would be the pattern I mentioned earlier would it calver ? The weber DCOE carb range of carbs are infinitely adjustable. I see earlier you quoted Vizard, If you recheck your book I think you'll find the 40dcoe in vizards graphs is fitted with 36mm chokes.

just you don't seem to understand what is been said. What your not getting is a weber fitted with different ie smaller chokes will perform very well, much better than any single SU. Especially the HIF44, a 40 dcoe would show a substantial increase in torque over a single HIF.

wrong again, Smiffy. I never quoted Vizard. I merely suggested that paulrockliffe read Vizard for some information on the subject.

It is YOU who "just doesn't seem to understand what has been said". "What YOU're not getting" is that this is a STOCK engine. It doesn't NEED a WEBER.

You keep stating the obvious, i.e. "The Weber DCOE carb range of carbs are infinitely adjustable." Do you really think you're the only one here who knows this?

In all of your rush to convince us you're a Weber expert, you lose sight of the key point that an SU is a better carb choice for this standard engine.

I run a 45 DCOE on my race Mini and am well familiar with Webers. So WHAT? I would never run one on a standard engine.

So save us all of your smokescreen. Do you honestly think that anyone is impressed with your Weber experience? It obviously didn't teach you much about the fundamentals.

As Frog said, an SU is simply a better choice than a Weber for a standard engine.

Get over it. Maybe it is YOU who needs to read Vizard.

I really don't understand this fascination with Webers, when 9 out of ten times for most folks engines a single SU would be more than man enough, especially in this case. I guess it's just pub points/talk ??
The guy has a standard MG Metro engine fitted, the single HIF44 will be more than adequate, he doesn't need a Weber & will gain nothing from fitting one, other than the headache of setting it up.

The be all and end all of this would be to actually try this conversion wouldn't it ! The DCOE is a bette carb than the 28/36DCD and the 28/36 will out perform the HIF44 on the MG metro engine. With the HIF it started to struggle in the higher rev range above 6000rpms, with the weber it would still pull right upto the redline.
Just as a comparison, the 28/36 was fitted to the last 1380 I built before the a new 45, obviously the performance improved & when on an economy drive fuel consumption didn't hardly change.

Paul fit a 40 you won't be disappointed.

At the end of the day I am not interested in arguing with anyone, all I can do is quote from experience of what I have done over the years, yes the DCOE weber is an excellent carb which can be adjusted to suit most applications but from experience which is something that some people don't have they just quote books, for a standard 1275 mg metor lump you can't beat an HIF 44 or HS6 which when jetted & set up properly will return just as good torque figures etc as a DCOE. When you start talking fully tuned 1380's etc then yes this is when a DCOE can come into it's own but still I would not recommend a DCOE for a road car when you could use twin HS2's or HS4's instead, I believe these are fitted to parallel manifolds so a straight flow into the head !! Even though I ran several race engines all set up at various rolling roads over the years one thing stayed constant and that was after a while you would get the smell of petrol in the oil this is when the DCOE washes the bores with petrol, this was also confirmed by the aforementioned rolling roads as a downside of a DCOE. It's ok if you regularly change the oil.

[Nightrain]

Bore washing is not a symptom with these carbs, it is a problem with the set-up !

thanks, Turbo Phil. I wish you had gotten involved earlier.

[midridge2]

The words dog and bone spring to mind.

[tuktuk]

im sure the OP wasnt wanting a webber for more power or torque... just to have a carb where he doesnt need to modify his bonnet to fit it ?

''fit under the bonnet of my Minus without spoiling my beautiful lines ''

Some people you just can't teach !

I like how this thread (that I am really interested in as I have a DCOE 40 I might put onto a 1275) has just turned into an argument lol

It seems that webers can be tuned to run efficently if they are setup correctly and are good for race use, After reading through all this lot I have come to the conclusion that for a 1275 engine its probably best to go for a HIF44 or twin HS4s, but in regards to the space issue in the original question....Reece Fish carb anyone? its sleek and it also sorts the fueling out for itself lol

can't you build/modify a manifold to fit the HIF44 ???

[mini7boy]

You're living proof of that statement, Smiffy. You keep popping off and keep getting proven wrong, thread after thread.

We've tried to teach you, but you just can't learn. And buy a *removed* dictionary while you're at it.

That would make sense I think I mean if you are 100% needing a sleeker bodyline then im sure you can nab a few old manifolds and get someone to weld some pipe onto it
