HEck cARBuRETTOR BAsIc sETTINGs
The engine of Monster Truck chassis „HOTLANDER NEXT GENERATION" is equipped with an ABC assembly.
ABC means "Aluminum", "Brass" and "Chrome".
Aluminum with its relatively small thermal expansion and small weight serves as material for the piston. The
light piston allows high revolutions and quick load-cycle changes through the small mass inertia. The cylinder
is made of brass with chrome-plated contact surface and has a slightly conical shape which narrows upwards
(in the range from 1 –  micrometer). During operation, the upper part of the cylinder heats via the glow plug
and the combustion procedures; it expands, thus giving the cylinder sleeve its exact cylindrical shape for the
optimal tuning of the piston. In this way, piston rings are preserved, which reduces frictional loss to a minimum
and excludes leakages. These engines are manufactured according to high technical outlays with precision
machining. However, small manufacturing tolerances cannot be avoided, just as little as slight unevenness and
roughness of the material.
In addition, there aredeformations due to thermal and mechanical stress.
Thus, when driving the new engine, a certain break-in time must be observed.
During the break-in time, engine parts tune to one another, whereby maximal capacity is reached and premature
wear is avoided.
Thus, the break-in procedure must be carried out with the highest accuracy!
The following must be observed during initial break-in:
- Low engine speed
- Rich fuel- air mix
- Short runtimes with cooling down phases (each phase approx. 3 minutes)
- Runtimes (mere engine runtime) totaling approx. 45 minutes

AsIc sETTINGs Of THE cARBuRETTOR
The carburettor of Monster Truck "HOTLANDER NEXT GENERATION" is characterized by a material combination of a new type
made of plastic and metal.
The low thermal absorption of the synthetic material, compared to a carburettor made of metal only, reduces the evaporation of the fuel
mixture already in the carburettor.
Thus, the fuel supply can be more precise, even with a hot engine and can be regulated in a simpler way.

HROTTLE sTOp scREW
The throttle stop screw is the small screw next to the idle speed-mix adjusting screw.
It is already pre-adjusted;
a readjustment should not be necessary. The idle speed adjusting screw regula-
tes the position of the slide carburettor (the choke limit stop) and therewith the
carburettor outlet in idle speed.
We recommend a carburettor outlet of approximately 1 mm.
Turning the adjusting screw clockwise widens the outlet, turning it anticlockwise
causes the slide to retract further, which reduces the opening.

AIN NOzzLE NEEDLE
MIX ADjusTING scREW
The main nozzle needle is located above the fuel supply to the carburettor. It is
adjusted for the first start of the engine and should not be modified yet.
The main nozzle needle regulates the air / fuel mix by full throttle. Turn the screw clockwise in order to make the mix "leaner" (to reduce the pro-
portion of fuel) and turn it anticlockwise in order to make the mix "richer".
In the basic setting for the first start, the main nozzle needle must be completely screwed in then unscrewed by two to three rotations.
