Best carby for 2A petrol

**isuzurover** · 14th March 2008, 10:52 PM

What the others have said is good advice - except for using a holden carby if you want to go anywhere near a hill offroad.

I had a 36IV on mine (after I tossed the stromberg in the bin) and was happy with it - except for the warping problems they are prone to.

The IIA I built for my dad has a Weber 32/34 (?) DMTL twin barrel, from a 2.5P (need inlet manifold or an adaptor). It is a very good carb IME.

I know people who have used the Stromberg CD Carb from a Rover 6cyl engine (the only good art about that motor!) on a 2.25 with a custom adaptor - the carb needs to sit on about a 30deg. incline. The rover 6 and V8 strombergs are a completely different carb to the holden stromberg.

cheers

The main advantage of the Zenith is not so much the size of the bowl as the fact that the split float arranged around the emulsion block means that the level of fuel relative to the metering bits is pretty much the same regardless of angle for any angle that is going to have the wheelsstill on the ground. The Solex does not have this, but certainly seems not to worry too much about angle.

Wasn't the Webber 34ICH also the OEM fitting for very late Series III 2 1/4 litre? Or is that just because lots have been swapped???
A good carby by most accounts.

Thanks for the advice.

I have now put the stromberg on (52 jet) and it has a flat spot as you rev up slowly. Shining a torch down the throat I notice it is when the the fuel ends coming in from the fuel pump one to the one that comes in right in the middle. There is momentary pause between fuel entering from anywhere. If that makes sense!! When I rev it past the flat spot and fuel starts coming in the centre it rev properly. Hopefully that makes sense.

Is it the float level or is there an adjustment somewhere?

Cheers
