GOVERNORS FOR AV AND MV MODELS
AV and MV engines are fitted with a pneumatic governor
similar to the one already used on the previous TA and
VA engines.
For the speed control on the governor for AV and MV
engines, there is an adjusting screw for use on variable
speed engines.
To adjust the speed operate as follows:
- Turn the screw in a clockwise position to increase the
speed.
- Turn the screw in an anti-clockwise position to decrease
the speed. (Fig 5).
On AV and MV engines the governor spring must be fitted
(Fig 6) with the hooks inserted from the top.
The spring must be located in the second hole of the
carburettor throttle lever (Fig 7) to allow the opening of
the throttle in order to obtain maximum power.
MV engines with electronic ignition have only one hole in
the governor vane to connect the spring to.
