Thread: Solex versus Zenith

the best allrounder and offroader carby for the 2.25P is the zenith 36IV. The kits are still available for them.

Hey isuzurover,

This isn't the first time I've have heard this sort of comment about Strombergs but has anyone actually got any evidence or first hand accounts to substantiate these claims?

I have done Harvey, Moore River, Mundaring a few times and a lot of beach work and I've never had a problem with mine.

And what problems exactly are they meant to encounter, fuel starvation or a flat spot?

with the strombergs its a combination of fuel starvation on angles (hill climbs mainly when you really need them working) and vapor locking on shutdown.

there is a mod to install them rotated 180 degress but its a lot easier to drop on the zenith.

There was one fitted to my IIA when I first bought it.

There are a few workarounds, like turning the carby or bending the float down...

But Perth/WA has no serious hills to speak of. Everywhere here seems flat compared to the east coast. You would rarely have a problem here, and the hills are so short you would probably be past the steep bit before you noticed.

So let's say I never intend to drive offroad, and want to refurbish the Stromberg carby.

Is there an answer to the original question?

I think someone posted here once about a disastrous stall on a steep sealed road followed by a scary roll backwards downhill!

I would stick with the Solex or Zenith; it is after all what Rover decided worked best,

Got it in a nutshell Charlie.

Got caught many years ago in my '66 IIA SWB going up Mt Cynthia in Gippsland. Just before the summit the track becomes steeper for a stretch, well I didn't make it. Didn't hit it hard enough. It's a bad feeling when you run out of oomph! in low first. Fortunately my passenger was a big bloke who dived out the door and tossed a boulder as big as a house under the rear wheel as I sat driving the brake pedal through the floor.
I couldn't restart the engine and I reckon it was because the carby couldn't cope with the steepness of the track. Thought of pouring some petrol down the throat of the carby to get things going, but of course the spare fuel was burried under everything else in the back.
Then I remembered that the Solex carby's choke is a bit different from most carby's in that it richens the mixture not by restricting the air flow but by increasing the fuel flow. Pulled the choke out and the engine then restarted. 4000RPM, slipping the clutch and spraying gravel like crazy I got moving and made it to the helipad at the summit. My mate and my missus to be walked up cos I wasn't stopping. Couldn't have done this with a conventional carby.
As Charlie says, give LR's engineers some credit, they knew what they were doing when they chose the Solex carby for this engine.

This is also useful when you need a little bit more torque to cross a sand dune, or when you get a bit of water going through the main jet and you need to introduce some petrol via a different jet. Both of these tricks only work with a Solex carburettor, as they add more fuel via a different route, rather than restrict air.
