If the engine does not start or briefly starts and then stalls,
connect the glow plug igniter for 10 seconds and then try
again. This way the glow plug will burn the excess fuel and
heat up the filament to start the combustion.
It’s possible during engine startup to have
an hydraulic lock of the engine, due to
flooding. Flooding happens when the
cylinder fills up with too much fuel. If the
engine is flooded, remove the glow plug,
stop the flow of fuel to the engine and
operate the engine by hand to eliminate the
fuel excess. Be careful to cover the head
with a cloth to avoid fuel spraying into eyes.
If the startup problems persist, check the following
points:
•
Is the glow plug igniter charged and functional?
Check the batteries.
•
Is the glow plug filament incandescent and
functional? Check the filament for damage.
•
Does the fuel reach the carburetor? Check the tank
and the connecting pipe.
•
Is the engine flooded? Remove excess fuel using the
procedure explained above.
BREAK-IN
An engine is a complex mechanical device. In order to get the
best performance from the engine, a break-in procedure for
all the internal and moving parts is absolutely necessary. A
proper break-in will greatly improve the longevity and
performance of the engine. Break-in will take some time to
complete, but the benefits are worth the time spent.
Always make adjustments in small increments during break-
in: this is an important mind-set to conform to, especially
when operating a new engine. Internal parts must be
properly lubricated and reach the correct temperature before
delivering maximum power. Using a lean fuel mixture or
running the engine at high RPM during break-in will
irremediably decrease its lifespan and performance.
