manufactured from 1964 up until 1992.
are a number of variations of this type of
engine due to technical development and uses. It
is interesting to note that the original design continued production until 1992
when along the way other models came out like the Lister AC-1, a 7HP engine with
a few design changes like the option to run a half engine speed PTO, electric,
crank or rope start, various fuel tank, muffler and air-cleaner options and the
elimination of the need for a priming cup to start the engine.
Other than that it is basically the same as the AA-1.
The engine was available with a cord pull start or a crank handle start depending on the buyers preference. These engines can be found powering generators, water pumps, cement mixers, hydraulic pumps etcetera.
