hi everyone
my carbs leaking a bit so im thinking of replacing it
is this the the right one for a 1957 948cc with an oilbath air filter?????
if it is are they readily avalible????

and it has a brass float

here is some pics<br><br>

and another<br><br>

and finaly another any info would help alot???<br><br>

It is the 'right' carb for that year model -not the best of course! What's wrong with yours ?

That looks like an H2 carb for an early 948 You would probably be better with an HS2 which was fitted from 1960 on.
Check the code on the needle shaft. It should be an M. Just swap the needles over if they are different.

ive got some numbers of the carb
carb co birmingham
aug 4815 next to this in small print is pdc2
and then on the lid of the float chamber is 1160l
what do these numbers meen???????????
answer to bmc question
its leaking petrol and oil as someone has messed around with it before we got it

Well - could be faulty float valve if it's coming over at the float bowl - easily replaced. If it's leaking down the main jet - just tighten the gland nut slightly! Can't see it leaking oil - there is only a teaspoonful in the dashpot - and it's common to have to top that up from time to time.

you cant see the oil from the pics but its dripping down on to the panel with the holes (quit a puddle) ive replaced the float and seal on the lid and the cyclinder.
ive also noticed when you turn the engine off theirs steem that comes off it.

what the best replacement to increase the power??????

An upgrade would be an HS4 or HIF 38 but you would need to change the manifolds.

So is this the correct carb for a late '58 too? I was wondering why I have one in a box in the shed but I've always had the later paper-filter type fitted.

If not I have one of these in my shed. Not sure of the condition as I've never had it on an engine but must have appeared from somewhere, I thought it was from my old '54.

Steam coming off it ????????? Water can certainly condense on carbs - the evaporating fuel is an effective refrigerant and so water condenses on the cold surface - which I suppose could in turn start to evaporate off again as heat transfers through on switch off - but it does seem a bit unlikely! It won't be 'oil' dripping off - it will be condensed fuel. When the Ignition is on - does the pump give a regular click - and is the base of the carb wet with fuel ?

the float chambers is dry on the outside but the rest of the carb is wet in fual and oil
i want to upgrade it anyway but i dont want to change the spring position the manifolds or the oilbath air filter.
whats the posible upgrades for a 948cc????

The manifold is the main power-zapping problem on that engine ! If you keep it = all you can fit is the later HS2.

will it make a difference?????

could make adifferance to your speed

The later HS2 won't make much difference to performance at all. If you want to make a start on improving performance you need an HIF38 on an MG metro inlet manifold with an LCB exhaust manifold (which reminds me - Josh - where are those pics?) and an 1.5" exhaust system out the back. Then move onto different head and cams after that..... The 948 can easily be made to put out about 60bhp which is most respectable

But not with that power zapping manifold!

Which is why I said MG inlet and LCB outlet ;-)

But he specifically doesn't want to change the manifold!! Or the oil bath air cleaner!!

Ahh, OK. Then as stated - only option is a replacement HS2 but it won't make any difference to performance, but it will look "period" and allow the use of manifold and oil bath filter....
