First, fully extend your antenna and turn the transmitter on. If the
green light ever goes dark or the red light comes on, your transmitter
batteries are low. You should replace them right away. Next turn on
the car’s receiver.
After fi lling the fuel tank, prime the
engine by pressing the priming button
three times. Then pull the engine starter
handle two or three times to circulate the
fuel into the engine.
Attach a fully charged 1.5 volt glow
plug ignitor to the engine and wait three
seconds to allow the glow plug to heat up (See Figure 13). During
break in, it may be necessary to leave
the glow plug ignitor attached to the
engine to keep it running while the
air-fuel mixture is adjusted.

Megatech’s MegaNitor rechargeable glow
plug ignitor allows easy starting, and can be
left on the engine to keep it running reliably
during break in.
Important: Start the engine using short quick
pulls on the starter handle straight away from
the engine. Do not pull the handle all the way
out or at an angle. Always let the starter handle
back in slowly after each pull. Do not let the
handle go and snap back into the engine.
Once the engine is running, make sure the
throttle trigger is set at idle. If the speed is
too high, open the low speed valve
(counterclockwise) until the engine speed slows to a safe idle. If the
engine stops or runs too rich (lots of smoke and liquid fuel droplets
coming from the exhaust), then close the low speed needle valve
(clockwise) until the engine reaches a reliable idle speed. Adjust the low
speed needle valve so the engine idles as rich as possible while still
running. If the engine will not keep running consistently at idle, turn the
idle speed screw 1/4 turn clockwise to increase minimum speed.
