Showtime - Carson Virus 4.0 GP V21 Betriebsanleitung

SHOWTIME... ALMOST!
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 "FAT
BONE" 50 090 5034 or platform and place the car so that the wheels
are off the ground and free.
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-venti-
lated area, such as your driveway. Unburned 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 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. (Attention! Do not touch!) 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 (outside temperature 8°C).
• Idle stop screw: approx. 1 mm air gap;
• High speed needle valve: screw in completely, then open 4 full
turns;
• 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 tempera-
ture 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.
