[Gasification] Governors and engine control.

[Ken Calvert]

GF and all, its a lot cheaper than you think!
You buy a "cruise control" kit from your local AutoParts warehouse.  Most of 
them get the road speed by operating a  magnetic sensor or Hall effect 
device against one or more magnets
clipped onto the  drive shaft or a  wheel.   Some of them work with a  light 
detector diode that senses a spot of white paint on a rotating part.  So, 
then you araldite a button magnet on the flywheel of your engine and petrol 
diesel gas whatever, away you go.  Ken C.
