2. Clean the electrodes by scraping with a

wire brush to remove carbon deposits.

3. Inspect for cracked porcelain or other

wear and damage. If any wear or

damage is evident, replace with a new

spark plug.

4. Check the spark plug gap and reset if

necessary. The correct gap should be

.030 inches (.75 mm). To change the

gap, bend only the side electrode using

a spark plug tool.

5. Install and tighten the spark plug to 22

N·m (16 ft. lbs.). Reconnect the spark

plug wire lead.

See the engine operator’s manual for the

recommended spark plug.

COOLING SYSTEM CLEANING

Before each use check to make sure the air

intake screen is free from grass and debris

and clean if necessary.

Every 100 hours of operation, check and

clean the cooling fins and inside the engine

shrouds to remove grass, chaff or dirt

clogging the cooling system and causing

overheating.

TIRE AND WHEEL SERVICE

Visually inspect the tires before each use. Do

not run the tires under- or over-inflated which

can cause tire damage. The correct tire

pressure for the front tires is 20 p.s.i.

(82.7 kpa) and rear wheels is 12 p.s.i. (137.9

kpa) (see figure 28).

When reinstalling the wheel after service, be

sure to torque the nuts to 75 ft. lbs. (101

N•m). Drive 200 – 250 yards and then re-

torque.

CAUTION: Do not run the engine

before all cooling system parts

are reinstalled to keep the cooling

and carburetion as intended.

CAUTION: Separation of a tire

and rim can cause an explosion

that could cause serious injury or

death.

Check the tires for low pressure,

cuts, bubbles, damaged rims, or

missing lug bolts and nuts.

Always use a clip-on chuck with

an extension long enough to allow

you to stand on one side of the

wheel while inflating the tires. Do

not stand directly in front of the

tire while inflating.

Never weld or heat a tire and

wheel assembly. The heat can

cause the air inside of the tire to

expand and result in a tire

explosion. Welding also can

structurally weaken or deform the

wheel.
