carb compatibility

I am going to send off my zenith carb for reconditioning at some
point but still want to be able to drive around, so have been
looking on egay for substitute ones to slap on for a week or so
before selling again. There are a few Zeniths on there listed to
fit Series 2 engines, will they fit straight on my series 3
engine or do they differ in any way?
thanks,
matt

Why don't you just buy a kit and recondition it your self, Mat?
It's a pretty satisfying job and somewhat less expensive for the
experience.
It's not a bad idea to have a spare carb and I'm assuming that
the one you've seen would be a 361V, which is the ideal Zenith.
There's a lot of argument regarding which is better on the 2
1/4; Weber or Zenith. But they both work and if set-up correctly
and maintained, they shouldn't give you hassle.
If I recall correctly, AllanI has/did have an SU on an adapted
manifold on his.

Matt, the Zenith 36IV was introduced with the 8:1 CR 2.25 engine
around 1967 for the last few years of 2a production. There is no
difference between that and the series 3 Zenith so they would go
straight on. Some I believe may have had a fuel shut off
solenoid but personally I've never seen one.
I agree with Drew, buy a decent overhaul kit and do it yourself.
A second hand original Zenith will have warped if it was going
to, and it is worth having a spare. My experience with the Weber
34ICH has been poor, I'd much rather have a Zenith, Solex or SU
carb.

Just done this job myself... Really easy..
Service kit from Burlen Fuel Systems..
Stripped and cleaned carb, lapped the top, bottom and emulsion
assy.. Blew the jets and fuel ways with an airline..Rebuilt and
fitted it...
Car started first time once float chamber full, once running al
that was needed was volume screw adjusting..
Kit and new volume screw £25 delivered...

I had one of those zeniths with a solenoid. Still warped non the
less. Get your finger out Matt and buy a second hand one while
your at Uni and rebuild it at leisure ready to swap and tune
when you get home. Job jobbed.

Thanks for the advice guys,
As basic rebuild cost £25 or so, yet a full professional
service, rebuild and basic setup tune from the Carburettor
Exchange is only about £100, thats why I was tempted to send it
off. this was compuonded by hearing first hand from a couple of
series owners that the self rebuild kits are quote "a waste of
time" unquote, followed by high recommendations of the carb
exchange. I dont know how worn it is inside on parts that may
not be included within a normal kit? I am assuming it is carb
wear as the economy is shocking depsite having checked
everything else and driving as carefully as possible?
Phil - when one does get rebuilt, it will be the current one as
I want to keep as many parts as possible original, hence the
ebay shitter one would be whacked on then sold off once finished
with - and I wouldnt have the time to rebuild it here anyway
even if my spanners and tools werent all at home.
thanks,
Matt

Mat, where's the Land-Rover (and with that the carb) presently?
If it's in Bristol with you, then you're going to need a spanner
to take it off.
I'm not trying to split hairs or be arsey here, but there aren't
that many tools needed to strip a carb; couple of small spanners
and a screwdriver, which you could buy locally (if your tools
are back at the ranch in Cheshire). And even with the price of
the rebuild kit, you still won't have breached that 100 quid
mark that Carb Exchange are asking. And it's only about an hour
of your time, which you could spend doing that instead of being
on here
And whilst we're on about the rebuild kits; I'd suggest that
whoever informed you that they are a waste of time either didn't
fit them correctly, didn't use all the parts in the envelope, or
just bought plain crap copies. I've rebuilt 361Vs for customers
where I was working and did the Strombergs on 'Acid Queen'...No
hassle and not a waste of time.
Seriously, friend. You're at university doing something
engineering-based, so get out to your Leafer and engineer.
Otherwise, every time you have a carb problem, if you haven't
familiarized yourself with the workings, you'll be taking it off
and sending it away...likely for no reason other than a slight
turn of the air regulator.
As an example...I recently bought a new Zenith for my Ferguson
tractor. The old, original Solex, I discovered, had pin-holes in
the floats, gaskets and seals were worn or shot and it pissed
petrol from wherever it could. But getting a kit for it would
seem impossible, despite this being France and the home of
Solex. So I bought a Zenith 24T2 which, like the Solex and the
operation of the tractor, is an up-draught carb, of which I have
no experience.
Setting the thing is turning-out to be a head-scratcher, with it
running well for a while, then hunting, then well again, then
not.
It's a mixture issue and only by familiarizing myself with
something new will I learn just how and why it is such a
sensitive balance on this kind of carb. But I'm screwed if it's
being sent away to have a wallet-bumming 'basic setup tune'. I'd
rather go in blind and learn, which is saying something for a
general techno-spaz.
Give it a go, Mat...you'll feel better for it.

Beware of just "whacking on an ebay shitter", as if the carb is
old and the O-ring at the bottom of the float chamber has
perished (or gone hard from standing around empty), then it
isn't going to run properly anyway and you will end up spending
money on a rebuild kit for that one too!
As all the others have said doing it yourself with the kit is
not a particularly difficult job to do, nor is it particularly
time-consuming. In fact it is one of the cleaner jobs you can
do on a Series, and you can also do it sitting at your desk,
saving yourself £75 to put in the fuel tank.

I've had three carbs reconditioned by the Carburettor Exchange
and had problems with all three of them.
1) Solex from FMW on the way to work one day conked out and
gushed fuel all over the manifold. Had to nip home and put a
spare carb on. Carb Ex fixed it for free, said something about a
small piece of rubber having stuck somewhere and caused it to
flood.
2) Solex from ambulance. In the middle of nowhere in the Owyhees
(Oregon) started running rough, stalling and black smoking.
Managed to keep going by using a bit of choke. Pulled the carb
off and found all the screws that hold the body together were
loose, presumably allowing air to be dragged in past a gasket.
Tightened them all up, it's been fine since.
3) Zenith from the 88 (proper old one). Ran fine for a while but
now won't idle and misfires. Pulled it off for the ACR SU
conversion, may simply be running on gas has killed the O ring.
Now I'm not saying any of this is really the Carb Ex's fault,
it's simply an illustration that once reconditioned you still
have plenty of opportunity for things to go wrong. Now I have a
go myself, the theory being if I screw it up I can always get
the pros to have a look afterwards.

Not the first carbs that I have heard of having problems after
rebuild. Ask Goose about his twin choke on KWD.
