Thread: Which carby is best for the 2.25 petrol engine?

How long is a piece of string? each carby has a following in regards to best. IMHO if it came with a solex, thats the best, If it was a zenith go for it. It really comes down to the jetting for a particular size engine, and each of those, if it came of a rover will be jetted for the basic performance needs of the motor. Where aftermarket carbs fall down is when the motor is called upon to do the offroad work, that is where a factory setup is best.

you want torque (solex), revs and maybe a little better economy but that was not my personal experience (zenith) or more vaporisation that you need (weber) tho they are significantly better if you have headers.

no doubt a heap will beg to differ but it has been my experience..

i run a solex ....

the zenith is the simplest and easiest to tune and field if its in good nick

the solex gives a wider rev range and responds better but is harder to setup and tune than the zenith

theres a bunch of webbers you can use, a single cd175 is nice, theres a handful of strombergs too but these need custom linkages and fittings.

My experience is that there is little to choose between the Zenith and the Solex in good condition.

The Zenith is easier to understand, and hence to rectify any problems that arise. Possibly easier to get parts for.

These are the only two that have been fitted to Landrover fours in Australia, and a problem with any others is both ensuring that the jets etc are appropriate and getting it set up and also troubleshooting any problems. OK if you are or have access to an expert on carburettors, but for most there are advantages in remaining standard.

Thanks for all your replies.

I have never heard of Zenith before and I have had a lot of experience with Solex on my 1972 Peugeot 504.

Can either of these be set up using the standard Landrover accelerator linkage or do they need a cable?

Thanks

I put a Zenith copy on DaOot.

It was a straight install with the linkages all lining up perfectly.

Carby worked a treat.

Both use the standard linkage. Note that the Zenith needs an adapter (554175) below it that twists the carburettor 90 degrees relative to the mounting bolts. The throttle shaft on the Solex is parallel to the mounting holes, where the Zenith has the two at right angles.

Late Series 3 used an accelerator cable I believe.

The zenith will last much longer using a cable I am lead to believe
