Yes, my late father had Fordson and Fordson Major tractors that were
like that, but I don't recall the smelly exhaust. The Ferguson he had
might have started off that way too, but he put a Perkins 3-cyl. diesel
in it.
I am guessing that they were optimized for running on TVO. Apart from
the greater cost of gasoline/petrol (even the red-dyed "commercial"
petrol, when that was available), they might not have run as well on the
latter.

Yup; my uncle, in the UK, had a Fordson tractor that started on petrol
and then changed over to paraffin (With ignition not in diesel mode
AFIK) in the 1940s.
Also on one occasion, here in NA, my Briggs and Stratton gasoline/
petrol mower ran out of fuel.
It was hot; so just for the heck of it I finished mowing using
kerosene/paraffin.
Also here to avoid waxing problems in storage cold climate and to
avoid need to for separate storage tanks in small community fuel
depots diesel and furnace oil were (and still are AFIK) the same
product.

I believe the only difference is dye and taxes. The DOT
is always after truck drivers using home heating oil to
run their trucks because it doesn't have the road tax
included in it's price.
