Service Notes - Briggs & Stratton E Series Service Information

SERVICE NOTES

Flywheel
The flywheel overlaps the governor crank at the top of the cylinder. There are two openings in the flywheel casting
to allow access to the governor nut, after the blower housing has been removed.
To remove the flywheel nut, remove the ignition armature and slip a flywheel strap wrench through the armature
opening in the flywheel guard (blower scroll). The flywheel can be removed from the crankshaft using Flywheel
Puller 19069.
Carburetor
For draining the bowl, there is a 1/4-turn hex plug with o-ring installed in the bottom of the float bowl. (CAUTION: Do
not attempt to unscrew the plug, as it is not threaded.)
The float bowl installs in the carburetor in only one direction. There is a cavity molded into the bowl that provides
clearance for the emulsion tube and jet. If the bowl cannot be fully seated into the carburetor by hand, turn it 180
degrees and then reinstall.
Note that the bowl screws are self-tapping. To avoid cross-threading when installing the screws, turn them
counterclockwise until the screw threads drop into place, then tighten clockwise.
The needle valve seat can be removed by threading in a screw, then clamping the screw head in a vise. Carefully
twist and pull on the carburetor body to extract the seat. When installing a replacement seat, make sure the
rounded edge is pressed into the opening in the carburetor body and the flat edge is facing the bowl.
Oil Capacity
This engine requires a reduced oil capacity of just 15 oz (.44 l). A new oil bottle has been designed for service
under part number 100113. The bottle contains the correct amount for this engine in support of our message to
consumers to "pour in the entire bottle".
Please make sure to remind customers that this engine requires only 15 oz (.44 L) and not the higher capacity of
our other engines.
We anticipate that overfilling could be an issue until customers become accustomed to the difference. Typical
symptoms of overfilling would be white smoke from the exhaust, sparkplug fouling, oil contamination of the air filter
and/or oil leaking from the air filter area.
Blower Housing Barcode Label
In the event that the engine blower housing must be replaced, the barcode label can be transferred to the new
blower housing as follows:
1. After installation, clean the surface of the new blower housing to remove any traces of dust, oil, or grease.
2. Wash hands thoroughly to remove dirt and oils from the skin.
3. Carefully peel off the label from the original blower housing and reposition it in the same location on the new
blower housing.
4. Press firmly to remove any air bubbles and ensure good adhesion.
