3) Turn the flywheel with the help of your starter box (do not
apply the glow plug driver) for about 3 seconds or when using a pull starter
pull 4 to 5 times so the fuel goes through the engine. When using the
starter box you will notice an increase of rpm, this means the fuel is going
through the engine and lubrification is making things easier.
4) Check to be certain that the throttle is closed and then apply
the glow driver on the glow plug and start the engine. If the engine does
not fire-up immediately, or does not make any sound that it wants to fire-
up, then do not keep trying and instead stop for a few seconds keeping
the glow driver on the glow plug. After about 10 seconds, try again to start
the engine, and if the engine still does not fire-up, repeat the process from
point 2. However, if the engine is flooded (too much fuel inside), then
remove the glow plug, open the throttle completely, cover the glow plug
hole with a piece of cloth, and turn over the flywheel with the starter box
(or pull starter). The excess fuel will be ejected through the glow plug hole.
Before mounting the glow plug again, check the operation of the glow plug
with the glow plug driver.
Attention: Hydraulic lockup is possible due to an excess of fuel in
the engine and causes the cylinder to flood and to prevent the piston
from moving upwards. If this happens, DO NOT keep trying to start
the engine, or damage may occur. The excessive fuel also prevents
the wire from glowing up correctly and so the engine will not start.
5) Once the engine has started, open the throttle a little to
gradually let the engine to warm up to operating temperature. This is an
important routine that you should always follow, especially when the engine
is still new. The internal parts need to receive lubrication and reach operating
temperature before pushing the engine to maximum performances.
