FUEL
The Walker jet engine is designed
to function with a GASOLINE/OIL
mixture.
We recommend using full-synthetic
based oils. During the running-in
stage, use an oil percentage of 3%
(33:1), and then 2,5% (40:1) once
this stage has been completed.
The gasoline must have an octane
number taht is not lower than 95,
in order not to run into pre-ignition
phenomena.
Carefully mix the gasoline with the
oil in a suitable can. It is advisable,
once they have been mixed, to use
the mixture within a month.
Do not use the vegetable or animal oil.
DO NOT MIX DIFFERENT TYPES OF
OIL TOGETHER.
CARBURETOR
The Walbro 37 carburetor, if used correctly, provides excellent performance,
requiring few tuning interventions. In any case, changes in climatic and height
conditions can affect functioning. The carburetor is adjusted during the testing
phase with a standard setting:
Srew H “ affects the entire range of use of the engine“. From completely
tightened, loosen by 1 1/4 turns or 450º “.
Screw L “ only has an effect at a low engine speed“. From completely
tightened, loosen by 1 turns or „360º “.
The carburetor is provided with a depression pump to remove the fuel from the
tank. The gap between the two must not exceed 50-60cm. The same applies to the
tube, which must not exceed 50-60cm.
It is advisable to insert a manual pump between the tank and the carburetor, so
that the mixture can reach the carburetor before the start-up, therefore avoiding
stressing the starter motor.
