Driving - Matchless 46/G3L 1946 Maintenance Manual And Instruction Book

DRIVING

3 FUEL
At the time of writing this instruction book only one grade of motor fuel is on sale
but it is certain that, very soon, the various grades of pre-war petrol will again be
available.
We recommend the use only of best quality fuel because the small amount of economy
that might be considered to accrue by using the cheaper fuels is more than offset by
the various advances obtained by only using Number One grades.
Fuel to which " Lead " has been added will materially prevent " pinking " but it is a
very debatable point whether the use of such a fuel, which discourages the use of the
gear box, is not generally detrimental. It must be remembered that the gear box
is there to used and therefore we suggest the use of " straight '' petrol plus the
free use of the gear box to prevent the engine labouring under heavy stresses at low
engine speeds.
4 FUEL SUPPLY
Two petrol taps are situated underneath the rear end of the petrol tank. (One each
side). Both must be shut off when the machine is left standing for more than a few
minutes.
The tap plungers work horizontally. To open, the hexagon knob (marked " Push-On ")
is pushed towards the body of the tap. To close, press the round milled knob (marked
" Push-Off " ) .
Normally, only use the tap on the left hand side of the machine and the other side will
then act as a reserve supply. Always re-fuel as soon as possible after being forced to
call upon the reserve, and then at once close the " reserve " tap.
It will be noted that, by fitting two petrol taps, it is possible to remove the petrol tank
from the machine without the necessity of first draining it of fuel.
