BEFORE HITTING THE TRACK
DO NOT ATTEMPT TO LIFT A KART WITH THE ENGINE RUNNING from the stand to the
ground. Always shut down the engine (turn off) and have a fully equipped driver seated and ready
to go before attempting to start and drive the kart.
Once the kart has been removed from the stand and is ready to drive make sure you reset the
carburetor is at least 1 ½ on the low and 1 ½ to 1 ¾ on the high.
Treat the tuning jets on the carburetor like a normal tap. 1/16th of a turn at a time for fi ne tuning.
Anti – Clockwise = RICHER, Clockwise = LEANER
ONLY the driver should start the kart, and once he equipped and ready to go and has been
instructed by any grid offi cial, start the engine by turning on the ignition, and pressing the start
button and the engine should start. If the engine is a bit lazy to start, lightly choke the air box to
give the engine extra fuel.
Once the engine has started, DO NOT IDLE THE KART WHILST STATIONARY, as the water
pump only operates while the rear wheels are turning. Also this will put excess wear on the clutch
and the clutch idler bearings. Simply start the engine and drive, you will warm the engine up
much faster under the load of driving than sitting stationary.

FINE TUNING
On hotter days and tracks at higher sea level you will need to run the carburetor setting slightly
leaner, this means that both the high and low speed needle/jets will need to be turn in ( clock-
wise approximately 1/16th to 1/8th of a turn on both, and on colder / low lying tracks the opposite
maybe required. Fine tuning is something you feel when driving.
