Metering Needle

Run the vehicle (with throttle fully open) over

the longest available straight course, in order

to observe the model's speed. Next return

the car to the starting point, close the Needle-

Valve 30° and repeat the run, taking note of

the improvement in performance.

Continue with further runs, gradually

reducing the Needle-Valve setting and

aiming to achieve the highest straight-line

speed. Remember, however, that, if the

Needle-Valve is shut down too far, the

engine will overheat and, accompanied by

visibly diminished exhaust smoke, the model

will lose speed. At this point, throttle down

immediately, stop the vehicle and reopen the

Needle-Valve 45-90° .
