Carburetor Float Level (Carburetor)
1. Run the engine at idle.
2. Check that the fuel level is at the center of the float
level indicator window.
If necessary, adjust the fuel float level. (Refer to Sec-
tion 4A.)
Hydraulic Lash Adjuster (12 valve)
Note
Tappet noise may occur if the engine is not
operated for an extended period of time. The
noise should stop after the engine has
reached normal operating temperature.
1. Check for tappet noise. If noise exsits, check the
following points.
(1) Engine oil condition and level
(2) Engine oil pressure (Refer to Section 2A)
2. If the noise does not stop, check for movement of
each HLA by pushing down each rocker arm by
hand while at TDC of compression stroke.
3. If the rocker arm moves down, replace the HLA.
(Refer to page 1A—75.)

TUNE-UP PROCEDURE 1 B
76G01A-102
TUNE-UP PROCEDURE
Tune the engine according to the procedures
described below.
Battery
1. Check for corrosion on the terminals, or loose ca-
ble connections.
If necessary, clean the clamps and tighten firmly.
2. Check that the electrolyte level is between the UP-
PER and LOWER marks.
Add distilled water if necessary.
3. Check the specific gravity by using a hydrometer.
If the specific gravity reading is 1.200 or less,
recharge the battery. (Refer to Section 5.)
76G01A-103
Air Cleaner Element
Visually check the air cleaner element for excessive
dirt, damage, or oil. Clean or replace if necessary.
Caution
When cleaning the air cleaner element, blow
dust off from the inside completely first, then
blow from the outside.
76G01B-005
Engine Oil
Check the engine oil level and condition with the oil
level gauge.
Add oil, or change it, if necessary.

Hydraulic Lash Adjuster (HLA)
Note
Tappet noise may occur if the engine is not
operated for an extended period of time. The
noise should stop after the engine has
reached normal operating temperature.
1. Check for tappet noise. If noise exists, check the
following points.
(1) Engine oil condition and level
(2) Engine oil pressure (Refer to Section 2A)
2. If the noise does not stop, check for movement of
each HLA by pushing it during disassembly.
3. If the HLA moves, replace the HLA. (Refer to page
1B—60.)
Ignition Timing
1. Warm up the engine and run it at idle.
2. Turn all electric loads OFF.
3. Connect a timing light tester.
4. Disconnect the vacuum hose from the vacuum
control, and plug the hose.
5. Check that the ignition timing mark (yellow) on the
crankshaft pulley and the timing mark on the tim-
ing belt cover are aligned.
Ignition timing: 12° ± 1° BTDC
(at idle speed)

If the specific gravity reading is 1.200 or less,
recharge the battery, by referring to Section 5.
Air Cleaner Element
Visually check the air cleaner element for being ex-
cessively dirty, damaged or oil.
Clean or replace it if necessary.
Caution
(Wet type)
