If the engine should need to be disassembled (e.g.
for cleaning or minor parts replacement) it is
advisable to return the Needle-Valve to the original
rich, starting setting and check whether further
running-in time is required before the car is raced
again. In the event of any major working parts (e,g,
piston/cylinder liner assembly) being replaced, the
complete running-in should be repeated.

Remember!

30º

Needle

The position of the needle-valve
when starting the engine.

Close the needle-valve approx.
30˚ after running the vehicle for
one full tank of fuel.
Repeat this procedure several
times.

30º

To stop the engine, close the throttle to idling speed,
then shut it off completely with the trim lever on the
transmitter. To cut off the fuel supply, pinch the fuel
delivery tube to the carburetor.

•

Repeat this procedure until 5 more tanks of fuel have
been consumed, during which time the throttle may
be opened for brief bursts of increased power. If the
engine stops at medium speeds, close the Mixture
Screw 45-90˚.

IF THE ENGINE FAILS TO START

Check the following:

Glowplug battery discharged or glowplug defunct.

Fuel not reaching carburetor.

•

•

•

MAX-12/15LD-X

Engine flooded.

Do not over-prime. (This could

also cause hydraulic lock and

damage the engine on application

of the electric starter.)

Remove glowplug, close needle-

valve and apply starter to pump

out surplus fuel. At this time cover

the plug hole with a rag so that

splashing out fuel may not come

into your eyes or mouth.
