3-4-4 Carburetor
NOTICE
At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Output
power will decrease, and fuel consumption will increase. Engine performance can be
improved by installing a smaller diameter main fuel jet in the carburetor and readjusting the
pilot screw. If you always operate the engine at altitudes higher than sea level 1000 meters
over, have our authorized dealer perform this carburetor modification. If not, should lower
load power in operating gasoline engine. Even equipped with suitable carburetor, engine
horsepower will decrease approximately 3.5% for each 300 meter increase in altitude. The
effect of altitude on horsepower will be lowered greater than this if no carburetor
modification is made.
If a carburetor suitable to high altitude is equipped with engine suitable to a lower altitude,
