Manifold required

[BriComp]

I have just purchased a 13/60, which has had quite a lot of mods.

Among those are twin H4 SU Carbs.

I consider these to be much too big for the engine and would like to get a/some carburettors more suited to the size of the engine.

I see my options as (a) twin 1.25 HS2s, (b) a single H4, or (c) put on my Reece Fish carburettor.

a) would seem to be fairly easy to source from a Spitfire. Does it matter what year/model. Any one any idea about needles. Apart from 0.030" off the head, I believe the rest of the engine to be standard.

b) where would I get a manifold from to do this?

c) this might be my preferred option, the Fish is a fantastic carburettor, but would require a manifold that would take a single 1.25" HS2 (Fish has same flange dimensions).

I should probably mention that the Exhaust manifold is a 4 into 2 into 1 tubular type.

What about a std 13/60 inlet and single stromberg 150? That would be easiest of all. 

The single HS4 and manifold from a Toledo or dolomite 1300 is the other easy option. 

A pair of HS2s off a mk3 or IV spitfire along with the mayching manifold from the same car. I would rather use the later MK IV carbs, a better design. 

If you wanted to experiment with your fish carb, I think you would need to make an adaptor plate and use either the herald or dolomite inlet manifold. Adaptor easy enough to make with some thick (15mm?) aluminium, a holesaw and some drills. Plus a tap for threading to take the carb studs.

Do you think that it would clear the tubular exhaust?

Yes, I had thought about that. In a way it's a stepping stone from the first.

I have no personal experience of heralds with a 4 branch manifold, but I would expect it to work.

I am sure somebody can confirm one way or another, or even a call to Canley Classics or another trader (most won't have the knowledge or experience of canleys)

Is it actually still a 13/60 engine in it? 
 

Even if it shows a GE engine number, is it standard?

Just bought the car, but it has history going back forever, and besides the Purchase of 2 off H4s and manifolds, the only change to the engine is to have the head skimmed 0.030" and hardened exhaust seats and valves installed.

Hi I have two 13/60 “single carb” inlet manifolds and 2 SU HS4 carburettors I don’t need. They are going to an Auto Jumble in Suffolk with some other assorted stuff in June if you are not interested?

I got a job lot off triumph parts off a friend, both of the HS4s need servicing kits and gaskets, they have been cleaned by me but they probably need a dip in an ultrasonic bath to give them a proper clean.

Both carbs need the float and float chamber cap and screws, my friend was a mechanic with his own garage - somehow he had mislaid these bits but they are not that expensive and easy to get.

I was going to get both carburettors restored but you could do that?

If interested, let me know
