My brother has corrected the timing and believes it's now a fuelling problem as the engine flooded at one point (though this may be becaue we blanked off the overflow on the carb). Either way, he's put it down to an issue with the carburettor and suggested I try a new/different carb.
Side Note: I didn't realise the carburettor needed a spacer plate, so my brother used the throttle lever off my old HS4 carburettor to create enough clearance between the carb and inlet. I also didn't have the abutment plate for the throttle cable, so the throttle and choke haven't been connected yet. We were controlling it manually on the carb.
Also, how does the water flow on the inlet manifold work and how to you plumb this in from where??

The heated manifold is controversial. It is actually fairly useless as it will not help cold starting until the water becomes at least warm, for obvious reasons! Also, heating the mixture reduces its density, so less power when hot. The only time I would see it as being useful is for prolonged running at low temperature, when carburettor icing is a possibility.
I would leave it disconnected for now, and focus on getting everything else working. It could be plumbed in with a driver-controlled valve, like the carburettor heat on an aircraft, so it can be off unless needed.

Looking at the second photo of the engine bay is the 1275 supposed to have such a bent clutch arm ?

I am almost certain that the bend is a bodge by someone who was having clutch problems.

That wouldn't stop the car from turning over, surely?

back to basics.
Turn engine by hand until TDC aligns on the pulley.
Remove plug from cyl 1 (radiator end) and check piston is TDC
Remove distributor cap and see where the arm is pointing (standard is 2 o clock position but dont worry if not).
Make a note of where the arm is pointing and fit the plug lead for cyl 1 closest to that.
Now fit the rest of the leads 1-3-4-2 anti clock wise.
Also what do you mean by not turning over? Turning over is starter motor turning engine to me. Not starting is the engine turning on starter, but not firing/running.

worth checking where the dizzy/rotor arm is pointing at TDC incase the dizzy shaft is 180 out.

What I've always tended to do is. With correction fluid or a paint marker, make a mark on the dizzy cap/body of the dizzy for no 1 ht lead, witch should be the top right/ 2 o'clock position. Rotate the engine by hand until it is at top dead centre for no.1. Remove the dizzy cap and see witch direction the rotor arm is pointing. Providing the engine/dizzy isn't 180 degrees out, the rotor should be near enough pointing at the mark you just made. If it isn't rotate the dizzy body so the rotor lines up the mark made, re fit the cap and try starting it. Once running adjust the timing as you normally would with the old strobe gun.

I've also got hold of a HIF38 carb this evening. The same problem more or less occurred, though on one or two occasions the car 'grumbled' but still didn't quite start.
Wondering if easy start might be my friend with this issue.
I also don't have the exhaust fitted, just the manifold and downpipe, so wondering if the lack of back pressure is making it more difficult.
