Honda Engines GCV520, GCV530, GXV530 Instructions Manual

Fuel
Gasoline is extremely flammable and is explosive under certain
conditions.
Refuel in a well-ventilated area with the engine stopped. Do not
smoke or allow flames or sparks in the area where the engine is
refueled or where gasoline is stored.
Be careful not to spill fuel when refueling. Spilled fuel or fuel
vapor may ignite. If any fuel is spilled, make sure the area is dry
before starting the engine.
Avoid repeated or prolonged contact with skin or breathing of
vapor.

GASOLINES CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol (gasohol), be
sure it’s octane rating is at least as high as that recommended by
Honda. There are two types of ‘‘gasohol’’: one containing ethanol,
and the other containing methanol. Do not use gasohol that
contains more than 10% ethanol. Do not use gasoline containing
methanol (methyl or wood alcohol) that does not also contain
cosolvents and corrosion inhibitors for methanol. Never use
gasoline containing more than 5%...

STARTING THE ENGINE
STARTING THE ENGINE WITH THE ELECTRIC STARTER
THROTTLE LEVER
SLOW CHOKE
The engine is equipped with a fuel-cut solenoid that allows fuel to
flow to the carburetor main jet when the engine switch is in the ON
or START position and stops the flow of fuel to the main jet when
the engine switch is in the OFF position.
The engine must be connected to the battery to energize the fuel-
cut solenoid, allowing the engine to run. If the battery is discon-
nected, fuel flow to the carburetor...

Turn the key to the START position and hold it there until the
engine starts. If the engine fails to start within 5 seconds, release
the key and wait about 10 seconds before operating the starter
again.
Operating the starter motor for more than 5 seconds can dam-
age the motor. If the engine fails to start, release the switch and
wait 10 seconds before operating the starter again.
If the speed of the starter motor drops after a period of time, it is
an indication that the battery should be recharged.

STARTING THE ENGINE WITH THE RECOIL STARTER
THROTTLE LEVER
SLOW CHOKE
Move the throttle lever to the CHOKE position to start a cold
engine. Leave the throttle lever in the SLOW position if the
engine is warm or the air temperature is high.
Turn the engine switch to the ON position.
Pull the starter grip lightly until resistance is felt, then pull
briskly.

Do not allow the starter grip to snap back against the engine.
Return it gently to prevent damage to the starter.

High altitude operation
Operation of the engine at an altitude lower than the carburetor is
jetted for may result in reduced performance, overheating, and
serious engine damage caused by an excessively lean air/fuel
mixture. At high altitude, the standard carburetor air-fuel mixture will be ex-
cessively rich. Performance will decrease, and fuel consumption
will increase.
High altitude performance can be improved by installing a smaller
diameter main fuel jet in the carburetor and readjusting the...

THROTTLE LEVER
THROTTLE LEVER
Do not disconnect the battery from the engine while the engine is
running. Disconnecting the battery causes the fuel-cut solenoid to
shut off the flow of fuel to the carburetor main jet, and the engine
will stop. If the throttle lever has been moved to the CHOKE position to
start the engine, gradually move it to the SLOW position as the
engine warms up.
Position the throttle lever for the desired engine speed.

STOPPING THE ENGINE
MAINTENANCE
The engine should be serviced by an authorized Honda dealer
unless the owner has proper tools and service data and feels he
is mechanically qualifired. To prevent accidental start-up, turn OFF the engine switch key
and disconnect the spark plug caps. Shut off the engine before performing any maintenance.

Use only genuine Honda parts or their equivalent. The use of
replacement parts which are not of equivalent quality may
damage the engine.
Maintenance Schedule Periodic inspection and adjustment of the Honda engine is
essential if high level performance is to be maintained. Regular
maintenance will also ensure a long service life. The required
service intervals and the kind of maintenance to be performed are
described on the table below.
