Webber carbs...

[KierenGG]

I would expect for £700+ you would get a noticeable improvement in performance...
Do you?

That is all

Depends :-)
Were they properly set up for your engine? What carbs did you have before?

edit: just saw you have an MGB too: is your engine modified in any way? If not, they won't do very much I'm afraid.

I haven't got any (Thats £700 that could go on paint don't you know!)
And just standard MGB GT carbs currently.

Edit:
Has a replacement Ivor Searle (?) engine fitted. Don't know if its boared out etc

As you have an MG, I agree that the money's better spent on the body :-D

Changing your SUs for refurbished ones could make a nice improvement (and an Aldon distributor and a Piper 270 cam). I'll stop now, as you want to save as much as possible for paint.

Would like to do the cam but don't fancy removing the entire engine

Don't even think of fitting Weber carbs (I'm guess multiple DCOE's or single DCOE) without the neccessary engine parts to enable all that extra fuel to be burnt correctly (bigger valves, cam, exhaust manifold, dizzy, blah, blah etc.,etc) as all it will do is drink lots more fuel & run worse, and you'll be out of pocket for zero benefit.

and before you go webers ream out the standard manifold and fit HS6s instead. Much better drivability, and only a little less noise.

A single Weber 38DGAS (originally fitted to the 3 litre Essex Capri) works very well on a mildly tuned Pinto (when suitably re-jetted) upto around 140bhp after which point a pair of twins are preferred. They are a popular budget tuning option with Locosters and grass trackers.

I bought a good one for £35 and it works very nicely on a mildly tuned (2.1 litre, unleaded head, tubular manifold, K&N filter) Pinto Powered Healey replica. Getting a Weber specialist to set it up properly on a rolling road shouldn't cost too much either - certainly much, much cheaper as a whole than a new pair of twin 40s.

On this carb the twin chokes are synchronized as opposed to sequential so mid range response and torque are improved over a standard single twin choke Weber - ideal for undulating B roads.

I wonder if a a suitable manifold could be adapted to try one on an MGB?

This pic shows the original carb but the position & manifold are the same on a Pinto:

The weber would be wasted on the B lump without other mods. It needs a decent head & cam & that will require a balance & also a lightened flywheel. Then you can go to a single DCOE. You can't run two as it is siamesed inlet ports, unless you run split DCOE which would only be worth it on a race lump.

Or unless you have a crossflow head...

Oyh
one thing at a time.....sort the bodywork out first.
Webers on their own will only cost you fuel
Spend the money (that you haven't got) on decent tyres, tele shock conversion possibly and a brake upgrade
Seriously, that looks like a lovely little car you have there just go out and enjoy it.. oh and by the way you don't need to take the engine out to change the cam, turn it on its roof and the followers will get out the way and not fall into the sump.

[KierenGG]

Don't go thinking in considering buying any because I'm not
Just wondered if they are actually 'that' good.

Properly set up, with appropriate engine mods then yes, a single 45DCOE on a B series will show a considerable improvement in top end go over a pair of HS4s. Bolted on to an otherwise standard engine you might see a small increase in power but a large increase in fuel consumption, made worse as you will want to plant your right foot all the time to listen to the intake roar.

My father has just bought a modified MGB with a webber 45 carb. Is running very rich/lumpy.
Can anyone recommend a decent rolling road who are experienced in setting up this kind of car.

Experience with a friend tells me that the correct manifold is very important if you put a Weber on an MGB. It took him a while though and some jet changes to get the engine to run smoothly. I have to say though that with my own cars once set up they virtually don't need touching again. The D-type on triple DCOE45s is smooth, tractable and powerful.Only problem is spitting back, especially when the ambient temperature is low.
