I have a 1953 E1ADKN Petrol / Kero Major but the vaporisor has been cut away from the intake manifold and a diesel exhaust manifold fitted with the intention to run only on petrol.
Are there any detrimental effects on running on petrol full time ?
Fuel consumption is very high - can I fit a smaller main jet, perhaps from the petrol Major ? It would be useful to know the carb ID.

Many thanks,

Michael.

Fuel consumption will be very high in the best of circumstances. You'll need petrol manifolds and a carburettor, as well as the air pipe.It'll never run properly with a diesel manifold, for it won't heat the intake manifold. Can't help with the carburettor any more, the jets and bodies are the non interchangeable parts. Running only on petrol will avoid bleeding it through into the oil, and you'll get more power. There isn't much on spark ignition engines that is easy or cheap to fix. Try looking around scrappys, you might yet find a vapouriser good enough to use, which is the easiest fix.

Thanks Sandy,

My current configuration uses the original vaporisor intake manifold with the heat box cut away and only the exhaust manifold is diesel - I shouldn't have to heat the intake for petrol. Are you saying that the main jet cant be removed ?
Also, when you say running on petrol will avoid bleeding - do you mean fuel dilution into the sump ?
Many thanks for the reply, I appreciate it. In some ways, it would be good to get it back to original if I can find an original vaporisor and manifolds, but what fuel would I use given that power kerosene is no longer available ?

Heat transfer is reqired by petrol, but far less than TVO. Here's a pic of Bob's Major showing what the petrol manifolds look like: https://postimg.cc/gallery/XvqVY6G#gallery-10
I do mean oil dilution, a big problem with TVO. Remember the manifolds and vapouriser are a single piece casting. Here's an old thread on the fuel, plus a discussion on red diesel that has come and gone time and again: https://www.fordsontractorpages.nl/phpb ... f=7&t=4221

If your E1ADKN TVO have a high fuel consumption ,here is what i have done to my Kero E1A :
Check the Carby is tight (no air sucking on any seal)
If you replaced the upper gasket {floadchamber) with an aftermarked gasket,be sure that there is a small venthole for the floatchamber in the gasket.On my new gasket was no venthole.The
fuel consumption was very high,After punching a venthole(ca. 2-3 mm dia )in the next new gasket and fitted,the fuel consumption was extrmemly lowered.
And a good cleaning of all parts in the Carby helps too.

If my memorys are correct,take a good sharp look at the upper lid from the carburettor,there must be a small hole in it,and exactly there must be a hole in the gasket.

Very good points here. Even with that in mind fuel consumption will be an issue, these engines at best empty a tank in just a day of work (compared to a whole week for the diesel ones, and with a spare gallon still left).

Since we're talking about the intake manifolds...

Why is mine different from Bob's (old52)?

Is mine a TVO intake manifold, or petrol?

For me yours and Bobs Manifold are the same.Yours have a somewhat heatshield (made of Tin) added,and Bobs is without this.There was never such a Shield factory mounted.
The TVO Inlet Manifold and the Outlet Manifold are casted at one piece.

In this Topic is a photo of this Manifold.

Jan has answered it perfectly, you have an extra shield fitted. Never available, not even on lorries.

Clearly I will have to remove it to see wth is going on.

It is CERTAINLY not a "tin heat shield", it is close to 1/4" thick and formed around the shape of the exhaust manifold.

I am guessing it was added to increase intake temperature above factory specs, but WHY?

Should I remove it? Don't want to remove the intake unless I really need to...

Looks to me like you've had a diesel manifold fitted too. You'll need to find a petrol one, only available second hand.
