Carburetor setting

The air/fuel mixture will vary depending on

atmospheric conditions. Therefore, it is nec-

essary to take into consideration the air pres-

sure, ambient temperature, humidity, etc.,

when adjusting the carburetor.

Perform a test run to check for proper engine

performance (e.g., throttle response) and

spark plug(-s) discoloration or fouling. Use

these readings to determine the best possi-

ble carburetor setting.

It is recommended to keep a record of all car-

buretor settings and external conditions (e.g.,

atmospheric conditions, track/surface condi-

tions, lap times) to make future carburetor set-

ting easier.

The carburetor is a part of the fuel line.

Therefore, be sure to install it in a well-

ventilated area, away from flammable

objects and any sources of fire.

Never look into the carburetor intake.

Flames may shoot out from the pipe if the

engine backfires while it is being started.

Gasoline may be discharged from the

accelerator pump nozzle when the carbu-

retor has been removed.
