(

BREAK-IN THE ENGINE BEFORE DRIVING THE CAR!)

TUNING AFTER BREAK-IN

Idle adjuster screw.

 
Lean

Rich

• Choose a wide clear outdoor location with low dirt and dust.
• Set the car on box or holder with wheels off the ground.
• Turn on radio and car.  Make sure throttle is at idle position.
• Fill fuel tank and set master engine needle.
• Prime fuel line and Heat glow plug before pull starting engine.
• When started, let engine fast idle for two tanks of fuel.

Close master needle by turning clockwise until it stops.  
Then open needle by turning counterclockwise 3 turns 
(rich setting). 

When running car, adjust carb with 1/8 clockwise turns, 
slowly leaner, until the top speed good.  Check engine 
temp, if possible, for no more 250 degrees.

Adjust barrel stop so it will not close, accept for a small gap.  
This gap will be the idle setting.  You will notice the idle will 
increase with a wide gap.

Adjust low end needle for best throttle response.  Use only 
small turns.  From idle, give it full throttle, if throttle is slow 
lean out needle until good.
