will it run on paraffin?

NO.
The ratio of AIR to fuel vapour would be all to Hell, and the chances are that IF it fired one cylinder and gave the engine a kick over, the sudden suck by the other cylinders would simply swamp all the cylinders with fresh air and wet kero spray = NO GO. On the other hand, if the glow plug was hot enough it might ignite the kerosene in the inlet manifold, and that could be quite exciting.
In a TVO engine, the INSIDE of the INLET manifold has to get and stay hot enough to VAPORISE all the fuel from droplets into GAS (aka vapour). The GAS will ignite by a decent spark. These engines all had special manifolds where the inlet was clamped tight to the exhaust, to make a HOT SPOT where all the fuel-air mix had to hit on the way to the cylinders. Essentially what this did was to turn a wet SPRAY of kerosene into a GAS or vapour.
In a petrol engine, there is enough petrol VAPOUR to light up from a spark, especially because it is helped by the heat of compression to 9 to 1 or so.
TVO engines are all LOW compression AND the fuel has virtually no vapour, so getting enough fuel into a GAS condition that will light by a spark isn't easy.
HEAT is the way to do it - start up on petrol, and have a HOT SPOT manifold.
It isn't worth it. Get a diesel engine.
I have a 2.5 NA here for the taking away of it.

would that be like a 21/4 manifold clamped together
Yes, but even more so.
The TVO manifolds often had fins inside to increase the very hot areas so that more of the fuel spray was heated into vapour / gas.
The 2.25 petrol manifold had a "hot spot" to assist vaporisation of the petrol, but I would doubt it had enough heat capability to vaporise kerosene.
If TVO engine doesn't burn all the kero, a whole lot of kero ends up in the engine oil, and soon enough bang goes the crankshaft bearings.
Seen it all too often in the "good old days".

i am aware how they work ,grew up with them ,would be possible to run on tvo but pointless ,may as well run red diesel

would parafin be a bit abrasive?
i mean its a basic fuel afterall.
re the hydrogen peroxide,
was that not what that german chappie used in his V1 & V2 rockets way back in 1940s.

A diesel engine will run on TVO / kerosene, but you would want to add about 10% at least of cheap engine oil to provide lubrication for the injection pump and the injectors.
There is virtually ZERO chance of any spark ignition engine running on gas-oil, red diesel, white diesel, which are all the same thing anyway

Paraffin / kerosene is a MUCH better fuel than petrol, pound for pound.
The problem is to get it lit up. A spark won't do it from cold, and it isn't as good in a diesel as the real oily diesel.
Kero is no more abrasive or corrosive than petrol or diesel, assuming all the fuels are CLEAN, as in well filtered.
The V-1 wasn't a rocket. It was a pulse-jet powered flying bomb, like a little aeroplane. The fuel was low grade gasoline.
The V-2 was a true rocket, and didn't "fly". The fuel was kerosene and liquid oxygen.

i used to have a tvo tractor and i actually ran it on jet a1 wich is basically parafin, mixed a bit of petrol with it but the main factor is the special hot spot carburetta wich vapourises the parafin that is why you had to start it on petrol and get it hot before switching to parafin, so if you can knock up some kind of device to vapourise the parafin then yes you can run on parafin

i meant may as well fit diesel engine and run on red if he wanted to save money at any risk

More likely to run on C1 premium paraffin (greenhouse heaters) than C2 Kerosene (domestic boilers). Land Rover engines were designed to run on low quality fuel, but not quite that low.
I'd say if you were to fit twin tanks and use a change over valve once hot there's a good chance she'll run. Perhaps put 1-2 gals petrol to a full tank of paraffin.
Not road legal but who's gonna know?

anybody with a sense of smell
Zillions of years ago when there was fuel rationing, I started my Series I on petrol then once the engine was warm, it ran on paraffin. I did upgrade the valves and seats to prevent a burn-out!
There again the paraffin was only a fraction of the price of petrol, and was delivered from a pump on the filling station forecourt!
No-one minded, including the then Customs & Excise, as they borrowed it occasionally because they couldn't get fuel for their vehicles!
Ahhh ... The good old days!

Yonks ago we used paraffin in the greenhouse heaters when we could buy it loose and it smelt and burnt better than this modern stuff,its as if they have downgraded it.

for heaters for home (paraffin heaters )or green house a premium paraffin was used as cleaner burn ,for modern heating systems heavier paraffin is used as is was cheaper and your not filling house with fumes
HHO is WATER.
It is not and cannot be a fuel.
It is a SCAM and FRAUD.
Do not get involved.
Read this, and if you don't understand it you are liable to be parted from your money by fraudsters.
a 2 litre engine running at 2,000 rpm (cruising 50 - 60) will draw in 1 litre of air per revolution, so 2,000 litres of air per minute.
Air weighs about 1.25 grams per litre, so the engine breathes about 2.5 KILOGRAMS of air a minute.
The fuel needs to be about a 10th to 20th of the mass of the air, so about 250 ~ 125 grams of fuel used per minute.
At 60 mph, and say 30 mpg, it will use 2 gallons an hour, say 8 pounds weight per gallon, 16 pounds of fuel, about 7 kilos of fuel, and a staggering 150 KILOS of air.
It is possible (easy) to ascertain from the water used what mass of hydrogen is produced. It is milligrams per hour, AND it takes more fuel to do it (by a factor of 3 to 4) than can be recovered by using the H2 as fuel!
It's a fraud.
