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.
