12-3 DISASSEMBLY AND REASSEMBLY
Mechanical failures aside, most carburetor malfunctions occur when the fuel/air ratio of the mixture is not
correct. This is usually caused by clogged jets, air passages and fuel passages, or by variations in the fuel
level.
To get the best possible performance from the carburetor, ensure that the each passages are kept clean so that
air and fuel can flow freely through them.
