Replacement carby

[numpty]

Does anyone know where I can source a replacement carby for a S1 in or around Brisbane. I understand that all S1's have the same Zenith, with different jets for different engines.

The carby on Leon, (a Zenith) is not the right one, and uses more fuel than I believe it should. And yes, I know they can be thirsty. I have been given the name of a company in Sydney that I will try on Monday (Indian made Zenith) but was hoping for something closer, as I'd like to have it fitted for the trip to Cooma.

Yes I know there are a myriad of carby's that probably fit, but I would like to keep it as standard as possible.

The Series 1's all had a Solex 32PB carburettor.

I have pasted the data of the jetting below - however it is out of format, so you will have to cut and paste it into another document. Or look at the page in the Trans Tasman Groups files section.

There is a reproduction carby made in India under licence to Solex, however as it is set up for a WWII Jeep you need to fiddle with the linkages a little. Master Chief knows where they are available.

Thanks Diana.

Master Chief informed me Hiltons replacement carb on his 80" was an Indian Zenith. A mix up I expect, and yes, he did tell me where to get one and that's the one in Sydney. I will try them tomorrow.

I've actually got an original on my 80", but think it's a little too far gone for the moment.

Hi there Diana

Your experties amaze me - you have just solved a little problem I have been having with the Fire Engine (running a little rough).


When engine governor is fitted to 1955-58 models, spec 1560 with alternative jets is used * Engines numbered 860001 to 861871, except those with governor

Theres different jets in the carby when the vehicle is fitted with Govenor.


Thanks

That is why we have kept the Yahoo Website for the TTS1 group - all there either in the files or the database sections. Always trying to add more.

WWII Jeeps, Ford and Willys, use a Carter carburettor.

I have no idea if you are right or wrong about WWII Jeeps - however I have been told that it is set up for a Jeep, (I assumed WWII) with wrong linkages for the Land Rover. There is a thread somewhere with the modifications required for the conversion.

Perhaps it is one of the Indian made jeeps of the 1950s and 60s who knows.

[numpty]

Well, I've had a look at the carby on the 80", and provided I can get a kit for it (4WD's in Melbourne list one), that might be the way to go. And yes, it is a Solex 32 PB, and with the jet sizes so kindly provided by Diana, we should be in business.

Why do you think I have a bunch of "Experts" hanging around? (called the experties*) :D:D:D

Actually it is most likely to old adage - "the empty vessel makes the most noise"! :(:(:(:(

P.S. * That one's for Ron "P38arover" otherwise it would be expertise.

Some additional information

Here are the Solex Part Nos, this carburettor does not appear to have been used on any other vehicle (from my Bendix Popular Parts Catalogue 1970):

Carburettor: 32PBI-2/1513 for 1.6 litre 1948/50; 32PBI-2/1560 for 2 litre 1951/54; 32PBI-2/1741 for 2 litre 1955/58.

Repair Kit - 1.6 1948/50 (RKS1513); 2 litre 1951/54 (RKS1560); 2 litre 1955/58 (RKS1741)

The following parts are different:
Main Jet - 50552/6/107.5 and 50552/6/115 and 50552/6/115 (The earliest 1.6 litre motors had a 102.5 Main Jet)
Compensating Jet - 51612-160 and 51612-170 and 51612-240
Economy Petrol Jet - 52824-50 and 52824-50 and 52824-75
Slow-running Jet - 50797/4/45 and 50797/4/55 and 50797/4/55
Pump or Speed Jet - 52200-50 and 52200-75 and 52200-75

The following parts are common to all three:
Throttle Shaft (50269); Idle mixture screw (1171); Pump piston or membrane (4X10138); Needle and Seating (51305/17); Washer for Needle and Seating (2261); Emulsion tube (52684); Slow-running Jet Air Bleed (51274/1/150); Starter Petrol Jet (52823-135); Starter Air Jet (50906-5.5); Gasket set (S2)

There are also different jets for Altitude and Tropical Conditions.

Wayne,
regarding the Governor. On 1.6 litre motors - there are quite a few differences in the carburettor. The different parts are the Throttle Lever, Accelerator Pump Complete, Main Jet (107.5), Lever for Accelerator Pump Rod, Control Rod for Accelerator Pump and I think also a different spring for the Control Rod.
It is possible the same applies in the later Series 1 motors also. After Cooma I may get a chance to go through the Rover Service Bulletins and other data I have.

Hope this helps,
Bob

If you are going to rebuild your own carburettor, remember to "machine" all flat surfaces using about 400 wet and dry, laid on a sheet of glass. You will notice that the threads in the bodies get pulled up, and the holes in the lids get pulled down. Upon re-assembly, do not overtighten the screw. Be sure to check for proper fit of the throttle butterfly cross shaft. If this is worn (they usually are) it will leak in air, and make it impossible to tune for a nice idle. To fix, ream housing, fit bushes, ream bushes, get/make new shaft, and fit. It may sound tricky, but it is the only way to make it run perfectly.

[graceysdad]

Nothing to do with the Landy as such but on shafts, I used to play with Ford V8 sidevalves a fair bit and the difference a rebushed base made compared to a worn base was incredible, sometimes just rebushing the base will make all the other problems go away. A V8 Sidebanger runs like a real sweety with a correctly tuned carby and when they dont suck air you can really tweak them up nice.

[Aaron IIA]

You got that correct about the shaft. I too just did a V8 sidevalve. It went from not running below 1000 rpm, to idling very sweetly at around 350 rpm. They are absolutely fantastic when tuned.

Thanks to Perry for supplying the jet sizes for the Solex 32PBI carby. I built my solex from the bits of 2 and Ken at Park Road Garage (Rocklea) adjusted it for me several years ago (it took him 30 seconds!). Now I have the engine running again with my new water pump the carby is flooding and leaking fuel so I might take it back to Ken for a complete service. The exhaust smells strongly of unburnt fuel and it runs rough when warm. :mad:

The fuel pump is shot so I have a temporary Jap one (Datsun I think). Anyone know if the pump is overriding the needle valve? If so will the carby overhaul fix it. Otherwise do I try and service the original pump or is a better idea to buy a NNS electronic replica?

Any help or experience gratefully accepted, Paul

[JDNSW]

Excessive pressure will certainly cause it to flood.

The maximum pressure I have in my reference for the pump is a fuel column of 61cm - that is about 1psi. While the carburetter would stand a little bit more than that, it would not take much to be excessive and is likely to be the case with a pump designed for installation near the tank. You can check the pressure your pump is giving by putting a piece of tubing on the output and seeing how high you can raise it and still get fuel flowing out of it.
