Figure 5. Engine Controls and Components
Honda GX270QWH2 Gasoline Engine
The engine (Figure 5) must be checked for proper lubrication
and filled with fuel prior to operation. Refer to the
manufacturers engine manual for instructions & details of
operation and servicing.
1. Fuel Tank/Fuel Filler Cap – Holds unleaded gasoline.
For additional information refer to engine owner's
manual. Remove this cap to add unleaded gasoline to
the fuel tank. Make sure cap is tightened securely. DO
NOT over fill.
Adding fuel to the tank should be done
only when the engine is stopped and
has had an opportunity to cool down.
In the event of a fuel spill, DO NOT
attempt to start the engine until the
fuel residue has been completely wiped up, and the
area surrounding the engine is dry.
2. Throttle Lever – Used to adjust engine RPM speed
(lever advanced forward
SLOW
, lever back toward
operator
FAST
).
3. Engine ON/OFF Switch – ON position permits engine
starting, OFF position stops engine operations.
4. Recoil Starter (pull rope) – Manual-starting method.
Pull the starter grip until resistance is felt, then pull
briskly and smoothly.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to
stop the flow of fuel.
6. Choke Lever – Used in the starting of a cold engine,
or in cold weather conditions. The choke enriches the
fuel mixture.

10. Oil Level Cap and Dipstick – Check engine oil with
engine stopped and in a level position.

Engine components can generate
extreme heat. To prevent burns, DO

is running or immediately after
operating. NEVER operate the engine
with the muffler removed.
Operating the engine without an
air filter, with a damaged air filter,
or a filter in need of replacement
will allow dirt to enter the engine,
causing rapid engine wear.

Set spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch)
Clean spark plug once a month.
9. Muffler – Used to reduce noise and emissions
