Since fitting a service kit on my zenith 36IV my landy has been running like a pig. It has since been to a local garage and they have done all they can to sort it out, when I picked it up they said see how you get on it's the best we can do. Apparently it is very worn.

I have a standard 2.24 petrol engine in a 83 series 3, does anyone have any experience of the copy Zenith carbs? I have read that a weber is not a good alternative and would like to keep it as close to original as possible.

Alternatively is there anyone who could recondition my existing carb?

Thank you for your help.

Paul

The weber 34ich is not that bad. They lose you a little power but save a useful amount of fuel, fit relatively easily and are pretty reliable.

DMTL32/34 for a 90 is better than a 34ICH but then you need to find manifolds for a 90 too and do some faffing to make the exhaust fit to the manifold (either replace the retainer ring or cut larger bolt slots. The advantages are even better economy, good low-end control and more power.

I fitted a copy zenith 2 years ago and the build quality is rubbish and it had a flat spot of idle from new that I couldn't get rid of and it did about 14 mpg.
Just fitted a new webber and done 180 miles and averaged 22 mpg which is a 109 ffr with a tilt so not the lightest or the most aerodynamic but I haven't noticed a difference in power if anything it goes beet er!

Was it working reasonably well before you rebuilt the carb? If so, have you put it back together correctly?Is the big o ring seal seated correctly? I'm not sure if it's possible, but could the jets be correct?

Its warped no doubt. Just forget a zen copy they are very poor quality. Mine was faulty out of the box. Weber 34ich all the way brand new cant fault them. Fit and forget almost.

Watch out there are copies of Webers around too which I've heard are also crap.

If you buy a second hand 34ICH or DMTL make sure its got the right jets in for a Land Rover as they have been fitted to a lot of different engines and may be jetted for a much smaller or larger or revvyer engine.

Having just fitted a Zenith copy to a 2a 2.25, so far i cant fault it, but would think if you wanted to do it right, get the original reconditioned. As mentioned above it may be warped which zenith carbys can do, also the butterfly valve fitting after years of use can start to wear away and let air in which may explain its rough running, but if you've replaced that in the rebuild, it most likely needs machining or jets adjusted. Webers are good, but as previously said you sacrifice a little power for some economy
