High Altitude Operation
(Fixed Main Carburetors)
When operating the engine at high altitudes, the main
fuel mixture tends to get over rich. An over rich mix-
ture can cause conditions such as black, sooty ex-
haust smoke, misfiring, loss of speed and power, poor
fuel economy, and poor or slow доуетог response.
To compensate for this, a special high altitude main
fuel jet is available for each carburetor. The high alti-
tude main fuel jet is sold in a kit which includes the jet
and necessary gaskets.
