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.
