FUEL SYSTEM
CARBURETOR OPERATION
Manual Starter System
When starter knob is pulled, fuel is drawn into the starter circuit from the float chamber.
The starter jet meters this fuel, which then flows into fuel pipe and mixes with the air coming from the
upper part of float chamber. The mixture, rich in fuel content, reaches starter plunger and mixes again
with the air coming through a passage extending from main bore.
The two successive mixings of fuel with air produce the proper fuel/air mixture for starting when the mix-
ture is sprayed out through starter outlet port into the main bore.
