Carburetor Servicing
WARNING
Accidental Starts can cause severe injury or
death.
Disconnect and ground spark plug lead(s)
before servicing.
Before working on engine or equipment, disable
engine as follows: 1) Disconnect spark plug lead(s). 2)
Disconnect negative (–) battery cable from battery.
NOTE: Main and slow jets are fi xed and size specifi c
and can be removed if required. Fixed jets for
high altitudes are available.
● Inspect carburetor body for cracks, holes, and other
wear or damage.
● Inspect fl oat for cracks, holes, and missing or
damaged fl oat tabs. Check fl oat hinge and shaft for
wear or damage.
● Inspect fuel inlet needle and seat for wear or damage.
● Inspect spring loaded choke plate to make sure it
moves freely on shaft.
1. Perform removal procedures for appropriate air
cleaner and carburetor outlined in Disassembly.
2. Clean exterior surfaces of dirt or foreign material
before disassembling carburetor. Remove bowl
retaining screws, or solenoid assembly on most
single cylinder engines, and carefully separate fuel
bowl from carburetor. Do not damage fuel bowl
O-rings. Transfer any remaining fuel into an
approved container. Save all parts. Fuel can also be
drained prior to bowl removal by loosening/removing
bowl drain screw.
3. Remove fl oat pin (some carburetors may have a
screw which requires removal), and inlet needle.
Seat for inlet needle is not serviceable and should
not be removed.
4. Clean carburetor bowl and inlet seat areas as
required.
5. Carefully remove main jets from carburetor. For
two-barrel carburetors, note and mark jets by
location for proper reassembly. Main jets may be
size/side specifi c. After main jets are removed, on
some carburetors, main nozzles can be removed
through bottom of main towers. Note orientation/
direction of nozzles. End with 2 raised shoulders
should be out/down adjacent to main jets. Save
parts for cleaning and reuse.
6. Position of slow jet varies and is removable only on
some styles of carburetors. See correct illustration
for corresponding style of carburetor showing
location. (On two-barrel carburetors, slow jets may
be sized to specifi c side. Mark or tag jets for proper
reassembly. Note small O-ring on bottom of each
jet.) Save parts for cleaning and reuse unless a jet
kit is also being installed. Clean slow jets using
compressed air. Do not use wire or carburetor
cleaner.
Carburetor is now disassembled for appropriate cleaning
and installation of parts in overhaul kit. See instructions
provided with repair kits for more detailed information.
