Engine break-in is the most important step to assuring that
your engine is fast and reliable throughout its life. Put simply:
DON'T SKIP THIS PART!
The engine is pre-set from the factory for break-in. Use a "Car
o
Stand" N 50 090 8071 or platform and place the car so that
the wheels are off the ground and rotate freely. Make sure the
throttle is set at neutral with your radio. Now actuate the starter
button on the transmitter. Keep the starter button pressed for a
maximum of 5 seconds! The engine will start.
Should the engine fail to start running, check whether the fuel
has been admitted to the carburettor inlet.
If not enough fuel has been admitted, hold a rag against the
exhaust and press the starter button again for 1 - 2 seconds
until the fuel reaches the carburettor.

If the engine has trouble idling at the rich setting, turn the idle
screw clockwise 1/8th of a turn at a time. This will increase the
idle allowing the car to break-in properly.
Try to do this in a well-ventilated area, such as your driveway.
Unburnt oil from the fuel will accumulate under the exhaust,
so be prepared. Let the car idle like this for 2-3 tanks of fuel
checking the engine temperature every 2 minutes.
Please allow a break of 10 – 15 minutes in between filling the
tank to allow the engine to cool down. You should be able to
touch the head of the engine with your fingertips and it will be
hot, but not uncomfortably so. If it seems very hot, richen (turn
counter-clockwise) the high-end AND low-end needles 1/8th of
a turn. Always use small increments when making these kinds
of adjustments.

Racer Tip:
Factory setting of carburettor:
With the following basic adjustment the engine starts
immediately, running perfect and rich enough
• Idle stop screw: approx. 1 mm air gap;
• High speed needle valve: screw in completely, then open 4
full turns;
Picture 7
Picture 8
• Low speed needle valve (linking): flush with the edge of the
linking arm, then 1 full turn clockwise;
After run-in is finished the high speed needle valve should be
open at least 3 and 1⁄4 turns. A richer setup is better if outside
temperature is high.
Racer Tip:
Drive your car slowly with the rich setting shortly after the
break-in period avoiding prolonged periods at full throttle.
Gradually lean out the mixture 1/8 of a turn at a time. The idle
will increase the more you lean the engine out.
