honda-automobiles gxv160 User Manual

A dirty air cleaner will restrict air flow to the carburetor and cause poor 
engine performance. Inspect the elements each time the engine is 
operated. You will need to clean the elements more frequently if you 
operate the engine in very dusty areas.

Operating the engine without an air cleaner or with a damaged air 
cleaner, will allow dirt to enter the engine, causing rapid engine wear. 
This type of damage is not covered under the Distributor’s Limited 
Warranty (see page 11).

Inspection   
1. Remove the two wing bolts, 

then remove the air cleaner 
cover. Be careful to prevent 
dirt and debris from falling 
into the air cleaner base.

2. Remove the paper element 

and the foam element from 
the air cleaner base.

3. Remove the foam element 

from the paper element.

4. Inspect the filter elements. 

Replace damaged 
elements. Clean or replace 
dirty elements.

Cleaning    
1. Remove the air cleaner 

cover and foam element, 
as described in the 
INSPECTION procedure  
above.

2. Remove the paper element from the air cleaner base.

3. Paper element: Tap the element several times on a hard surface to 

remove excess dirt, or blow compressed air [not exceeding 30 psi 
(207 kPa)] through the element from the wire screen side. Never try 
to brush off dirt; brushing will force dirt into the fibers. Replace the 
paper element if it is excessively dirty.

4. Foam element: Clean in warm, soapy water or nonflammable 

solvent, rinse and dry thoroughly. Do not use gasoline as a cleaning 
solvent, because that would create a risk of fire or explosion. Dip 
the element in clean engine oil, then squeeze out all excess oil.

Excess oil will restrict air flow through the foam element and may 
transfer to the paper element, soaking and clogging it.

5. Wipe dirt from the air cleaner base and cover using a moist rag. Be 

careful to prevent dirt from entering the air duct that leads to the 
carburetor.

6. Reinstall the air cleaner elements, and make sure both elements 

are properly positioned. Install the air cleaner cover and tighten the 
two wing bolts securely.

Recommended spark plugs: BPR5ES (NGK)

W16EPR-U (DENSO)

The recommended spark plugs are the correct heat range for normal 
engine operating temperatures.

For good performance, the 
spark plug must be properly 
gapped and free of deposits.

1. Disconnect the cap from 

the spark plug, and 
remove any dirt from the 
spark plug area.

2. Use the proper size spark 

plug wrench to remove the 
spark plug.

3. Inspect the spark plug. Replace it if 

damaged, badly fouled, if the 
sealing washer is in poor condition, 
or if the electrode is worn. If the 
spark plug is to be reused, clean it 
with a wire brush.

4. Measure the electrode gap with a 

suitable gauge. The correct gap is 
0.028 - 0.031 in (0.70 - 0.80 mm). If 
adjustment is needed, correct the 
gap by carefully bending the side 
electrode.

5. Install the spark plug carefully, by 

hand, to avoid cross-threading.

6. After the spark plug is seated, tighten with the proper size spark 

plug wrench to compress the washer.

7. When installing a new spark plug, tighten 1/2 turn after the spark 

plug seats to compress the washer.

8. When reinstalling the original spark plug, tighten 1/8 - 1/4 turn after 

the spark plug seats to compress the washer.

9. Attach the spark plug cap to the spark plug.

1. Start the engine outdoors, 

and let it warm up to normal 
operating temperature.

2. Move the throttle control to 

the slow (IDLE) position.

3. Using a screwdriver, turn the 

throttle stop screw to obtain 
the standard idle speed or 
the idle speed specified by 
the equipment 
manufacturer.

1,700 ± 150 rpm

2,100 ± 150 rpm
