Carburetor Settings
Small differences in fuel, temperature, height or strain can require slight adjust-
ment of carburetor. Only let engine run with air filter and air filter cap fitted.
Operation at high altitudes
To improve engine performance at high altitudes, fit a small-holed main jet to the
machine and readjust the mix control screw. This
measure is necessary, if the engine is permanently
operated at altitudes of 1,830 m plus above sea level.
I
If the engine is operated at a lower altitude than
carburetor calibration allows for and if too little
fuel is mixed in, power may drop, the engine may
overheat or even suffer serious damage.
