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
Stand" 908071 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. Place the glow heater onto the glow
plug and give the recoil a sharp pull (picture 4). Do not pull it
more than twelve inches! More than that may break the cord
and this is not covered under warranty. It is better to give the
recoil short sharp pulls rather than long ones. If the pull-start
cord gets stuck, rotate the flywheel a little bit with your finger.
This should make the cord automatically recoil. Within a few
pulls, the engine will start with a good puff of smoke.
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 immedia-
tely, running perfect and rich enough (outside temperature 8°C).
• Idle stop screw: approx. 1 mm air gap;
• High speed needle valve: screw in completely, then open 4
full turns;

richer

richer
• 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.
