Yamaha LB50IIAC - Yamaha Mixing Chamber Disassembly

c. The level is set according to the design
of the carburetor and float bowl
chamber. Under no circumstances
should float level be altered in an
attempt to correct a performance
problem. Look for the problem in other,
related
components or carburetor cir-
cuits.
d. If the carburetor is placed with the side
down, the float arm will contact the
float valve end.
e. Using a vernier caliper, measure the dis-
tance
of the float arm from the top of
the float chamber gasket seat (gasket
removed)
to the float arm.
Float level:
22.0±2.5 mm
NOTE:------------
The float arm should be just resting on,
but not depressing, the spring loaded in-
let needle.
f. To correct float arm height, bend the
tang a slight amount as required.
Both the right and left sides of the float
arm should measure identically.
Correct as required.
Disassembling the mixing chamber
1. Remove the mixing chamber top, and
remove
the throttle shaft bolt.
