Reassembly Procedure
Reassembly is essentially the reverse of the
disassembly procedure. Use new gaskets, springs and
adjusting screws as provided in the carburetor repair
kit. Also use new carburetor and intake manifold
gaskets. Set the idle speed (RPM) adjusting screw (if
equipped) 2-1/4 turns open for initial adjustment and
make final adjustments as described earlier.

Float Replacement
1. Clean the exterior surfaces of dirt or foreign
material before disassembling the carburetor.
Unseat the clamp and disconnect the accelerator
pump hose (if so equipped), from the upper fitting.
Remove the four fuel bowl screws and carefully
separate the fuel bowl from the carburetor. Do not
damage the O-Ring(s). Transfer any remaining
fuel into an approved container. Save all parts.
See Figure 5-8.

hanging down. See Figure 5-10.
