FUEL SYSTEM/CARBURETION
Carburetor Disassembly/Inspection
20. Inspect diaphragm for signs of hardening,
stretched or weak areas, holes, or tears.
21. Measure control arm height from machined
surface to top of plastic button on control arm.
NOTE: Top of plastic button #2 should be .060 "(1.5
mm) below casting surface #1 as per illustration at
right. Variances in control arm positioning will result
in incorrect fuel supply. If the control arm is too close
to the diaphragm, fuel levels will increase, resulting in
a rich operating condition. If the control arm is too far
below the casting parallel line a lean condition will re
sult.
22. Loosen screw and remove control arm and inlet
needle.
