Step 1 Select the combination of Cruise Mode and Power Mode fuel-metering stages
desired for your calibration. Normal calibration changes will be within the gridded
diagonal area. That is, Cruise and Power mode changes should be in the same
direction (either richer or leaner) and usually by the same amount.
Step 2 Find the number that is nearest your desired combination. This is your Calibration
Reference Number.
Step 3 Go to the next page. Find the Calibration Reference Number you have just selected
in Step 2. Listed will be the Main Jet and Metering Rod required to achieve the
desired fuel metering for the Primaries.
