Important! For best performance, maximum enjoyment and longest
service, your Q 1.6 HP engine must be properly broken in before you
adjust it for maximum power. Breaking in your engine enables match-
ing surfaces and parts to establish the correct running tolerances. Prop-
erly breaking in the engine during the fi rst tanks of fuel will
determine how well your engine will run for its entire life.
Breaking in simply requires you
to run three tanks of fuel
through the engine at reduced
power. It’s a great opportunity
to get used to driving your
AfterBurner before it
reaches maximum speed. After
the break in, you may adjust
your engine for maximum
power.
The engine is adjusted at the
factory for the correct break in
settings. If your settings somehow
get changed, simply close both the high speed and slow speed needle valves
by turning them clockwise, then:
• open the high speed needle valve three
complete turns
counterclockwise
• open the slow speed needle valve four full
turns
NOTE: Never force the needle valves closed .
Only close them until you feel slight resistance.
Before you start the engine, it’s important to
know the correct way of shutting it off. To do
this, carefully use needle nose pliers or your
fi ngers to squeeze the fuel supply line closed. If
you use your fi ngers to squeeze the tube, use
care or you might get burned. You should wrap
thick tape around the jaws of the pliers to
prevent damaging the fuel line. Squeezing this
tube closed for a few seconds is the only method
you should use to stop the engine.
