Engine Break In

service, your Megatech M-16 engine must be properly broken in before 

you adjust it for maximum power. Breaking in your engine enables 

matching surfaces and parts to establish the correct running tolerances. 

Properly 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 

Dark Thunder 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.

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.
