Other Carbies on 550SR autos??????

pugrambo:
80's falcon had i think a 32/36 weber

No, they're a Weber 34ADM. They have a 34mm first throat with a 27mm venturi and a 34mm second throat with a 29mm venturi. They have an electric auto choke and some of them have a dodgy idle jet system.

There's some bit's at:

The motorcraft carb you mentioned, ...2150...which particular "henry" is it off....2.0 l cortina/escort?

Good question! The 2100s were on the cortina I think! Some people say 2150 was on the V6 capri. However mine came off CJ7 jeep! There is an important differents between the two, 2150 has mechanically operated metering rod type air bleeds. 2100 does not! Some 2150s have a altitude comp as well.

It is not an easy swap! Hence my saying wait for my results.

I will most defenitly post the results!

Deka......

Have you got any details about the jetting your dad used on the R12 weber.

I may just go this way until I can work out how to adapt the stromberg/SU arrangement Ray and Graham spoke of.
After some research the "variable" carb's look like a good option for ecenomy.
Thanks alot guys!!!!!!!
And for now as my access to Renault parts is limitless so to speak I'll go that way

.....Two slight hassles there Ray, the manifold and the hook-up of the kickdown cable for the auto???
Shouldn't pose to much of a problem?

Are you any good at fabrication? I don't see it as a big job making an adaptor, though there are sure to be a number of different approaches you can take to how you do it.

The kickdown is just a matter of linkages.
 
Hi all,

Both my father and I have fitted Cortina-sourced Webers to 505s, and I have a 504 with one fitted by the previous owner. In every case the result was better performance and economy. The 1975 504 wagon, in particular, goes like a train.

Not sure what we have done right, as reading the posts here make it sound very complex! But in any case, it is an easy conversion requiring only a bit of fiddling with the accelerator cable fitting (the throttle control turns in the opposite direction to the Solex, so you have to reverse your return spring) and if you want to keep your Pug air cleaner you have to adapt it to the top of the carby. For an auto you need to add a bracket to hold the outer sheath of the kick-down cable near the throttle control. None of this is hard - in fact I think it could be done in an hour by somebody half-handy.

You can pick one of these old carbs up for $50-$100 from a Ford wrecker. Worth a try for the cost, I think. Twin SUs sound fun, though.

Cheers,
John Lane.
 
I had problems with the one on my car, John... lots of problems, but who knows where that all started?

As for the twin SUs, I imagine these would cause a fair bit of inconvenience. There would be difficulties with battery clearance, with access to the starter, with oil filler access and so on.

Achieveable, but less profitable, I'd think, than having the right single SU.

John,

I always use these Webers on my 504/505s and have also found them to be excellent. I agree the conversion is easy. I also agree that the conversion can take less than an hour (if you don't include the time taken to file or grind out the manifold).

Ok,
Back to this old thread....
Have located a pair of Volvo 144S twin SU carbies....1 3/4" with manifold and air-cleaner elements for $50.
Do I go this way or the single Stromb' off the Rover 2000?
Decisions decisions......
Some one suggested to me the other day to try an IDF weber from a rotary ???? (burning rice mallet )
Should I just scrap the old XNA-2 and drop a V6 in it. Go the whole hog and order Alpine V6 internals from Mecaparts and go forced induction?
A tyre smoking Pug wagon.
Graham do you still have the single Stromberg??
Cheers Chris
 
Ray Bell:
I always thought the Rover 2000 SU was a 2", but I got one and it was 1 3/4"... as is the Austin 1800 which might also have a chance of being okay.

Rover 2000 SC - single 1 3/4" SU, Rover 2000 TC - twin 2" SU.
Twin SUs are work bloody great once you have the nack of balancing them - great throaty roar when given a bit of stick.
But for a carby 504/505 motor, the best is a Ti head and twin twin throat sidedraght webers or dellortos. Broom broom!!
 
Plenty of reasons to say that's a load of rubbish...

Remember, some people want some semblence of economy, and we're talking about an unmodified engine, not one with a cam and high compression.

The twin carbies are not convenient to fit to the 504, you have things like alternators (possibly air cond compressors) and oil fillers to clear.
 
I replaced the weber on my just purchased 2litre 404 rally car with an early solex (SEIEA) and once again got a substantial performance increase. Some of the problem, of course was that the weber was on the wrong way around with the primary feeding the high flow inlet ports, reducing response and torque and the secondary the low flow port, reducing top end power.

In my opinion these carbies are the way to go on a standard motor.

I think the three branch manifold on my 73 504 can be taken off and Su's or side draft webers bolt straight up.

Graham has already tried that with a single 45mm DCOE. It apparently went OK but chewed alot of fuel.

It would probably work better with a 40mm DCOE with small venturis/chokes (like 28, 30 or 32mm). The smaller the venturi/choke the more accurate the fuel metering. 40mm Webers work better with small chokes than 45mm Webers do.
