Cars Produced:
March 1968 to September 1971:
According to noted authority, Anders Clausager, approximately 59,500 cars, all built at the
Morris factory at Cowley.
Production breakdown by year model:
This information is gathered from Commission Number information contained in factory BMC Microfiche
for the 1100/1300 line. Using this method to guage production numbers results in in a slightly lower number of
cars produced at 58,472, compared to the "approximate" 59,500 quoated from Anders Clausager's book on the ADO-16.

Carburetion:
Single
1-1/2" S.U. HS4 carburetor mounted to a combination intake/exhaust manifold.
Early cars had a fixed needle type carburetor. The later cars had a swinging needle
type carburetor.
The air filter housing had an intake tube that was bent into a curve shape. This could
be positioned "down" and placed into a heat shroud that was mounted around the #4 exhaust manifold runner for cool or cold
climate driving. Using this position helped prevent carburetor icing which led to misfiring at cruise speeds and stalling
in stop-and-go traffic. The intake tube could be mounted in the "up" position for warm weather driving.
An "Induction Heater" was fitted in a spacer block between
carburetor and intake manifold to heat the carburetor in very cold weather
prior to starting. Some models also had a carburetor piston dome heater band tied into the tempurature sencing switch
on the induction heater. (In cold weather, the owner's manual advised turning the ignition key to the "on" position
and letting the carb heaters run for a minute or two prior to cranking the engine over.)
