ENGINE BREAK-IN
For a new engine (break-in setting), the high speed needle needs to be set as rich as possible. Turn the
high speed needle 1/4 turn counterclockwise from initial setting (2.5 turns from fully closed). Repeat step
15b. Keep doing this until the engine stalls at full throttle, then turn the high speed needle 1/4 turn clockwise.
Run the car in an open parking lot with this rich engine setting for at least 5 tanks of fuel to complete the
break-in process. It is normal for a new engine to stall many times during this time due to the rich setting.
When it does, just restart the engine. After break-in, follow the ENGINE SETTING procedure to set the
carburetor for normal operations.
ENGINE SETTING
Due to different fuel formula, operating elevation, humidity . . . etc., the engine may/may not operate properly
at initial setting. Please follow the following procedure to achieve proper carburetor setting. Do not perform
this procedure until the engine has been properly broken in.
a. Start the engine.
b. With a running engine, run the car back and foreth in a straight line (full throttle achieved furing each
passage) in an open parking lot. Repeat and note the sound of the exhaust. Do not hold the throttle
open with car off the ground or the engine connecting rod may break.
c. If the exhaust does not reach a high pitch note, turn the high speed needle (long needle, extending from
carburetor body, pointing up) 1/4 turn clockwise, and repeat step 15b.
d. Repeat step 15c until the engine reaches optimum setting (turning in the high speed needle will no longer
have an effect at full throttle and turning out the needle will cause the engine's full throttle rpm to drop a
little). For normal operations, turn the high speed needle 1/4 turn counterclockwise from the optimum
setting.
e. To set the idle, turn the idle screw in (higher rpm) or out (lower rpm). Basically, the idle needs to be set
at the lowest possible point before the engine stalls.
f. To set the low speed needle (inside the throttle lever), the engine needs to be broken in and high speed
needle needs to be set first.
g. Repeating step 15b every 10 seconds (1 second full throttle and 10 seconds idle). If the engine rpm at
idle drops after a few seconds and stalls, then turn in the low speed needle (clockwise) 1/4 turn. If the
engine rpm stays the same or goes up at idle, then turn out the low speed needle (counterclockwise) 1/4
turn.
h. Keep repeating step 15g until the engine rpm drops (goes to idle rpm, then drops a few more rpm after a
few seconds) but does not stall.
