2.3. The oil pressure switch is preventing the engine from starting . Check the engine oil
level. If it is low, add oil to the proper level. If the engine still will not start, disconnect the
oil pressure switch. If the engine starts with the oil pressure switch disconnected, replace
the oil pressure switch.
2.3.1 Note: It is important to use only Briggs oil filters. Even though an after-market filter may
fit, the internal by-pass system may not be compatible with the Briggs engine resulting
in low oil pressure.
2.4. The high temperature switch has shut the engine down . Observe the temperature
gauge. If it is above the normal operating range (230° or above), allow the machine to cool
down. If it will still not start, disconnect the high temp switch. If the machine then starts,
replace the switch.

inspect the fuel lines between the fuel source and the carburetor. Repair or replace any
faulty parts as necessary.
3.1.1. If the pump is not working, check for 12 volts and a ground at the pump.
3.1.2. If 12 volts is not present at the pump, check the wiring to the pump, including the fuse.
Repair or replace as necessary. Note: If the fuse has blown, carefully inspect the
wiring for a shorted or damaged wire. Repair immediately.
3.1.3. If 12 volts is present at the pump and the ground is good, replace the pump.
3.2. The carb solenoid is malfunctioning . Test for 12 volts and proper ground at solenoid. If
both test okay, replace the solenoid.

Note: If the engine has been flooded, it may be necessary to remove and clean the spark
plugs.
3.4. The spark plugs are dirty or worn . Inspect and replace as necessary.
