Battery Charging

WARNING:

Explosive

Gas!

Batteries produce explosive hydrogen gas while being

charged. To prevent a fire or explosion,

charge

batteries only in well ventilated areas. Keep sparks,

open flames, and other sources of ignition a way from

the battery at all times. Keep batteries out of the reach

of children. Remove all jewelry

when servicing

batteries.

Before disconnecting

the negative (-) ground cable,

make sure all switches are OFF: If ON, a spark will

occur at the ground cable terminal which could cause

an explosion if hydrogen gas or gasoline vapors are

present.

Fuel Filter

Some engines are equipped

with an in-line fuel filter.

Periodically

inspect the filter and replace when dirty.

Use a genuine Kohler filter.

Carburetor Troubleshooting

and Adjustments

KTI 7 and KTI 9 engines are equipped with one of two

basic types of carburetors

- Kohler or VVa/bro - fixed

main jet or adjustable

main jet.

The carburetor

is designed to deliver the correct

fuel-to-air

mixture to the engine under all operating

conditions.

The main fuel and idle fuel needles on

adjustable jet carburetors

are set at the factory and

normally do not require further adjustment.

On fixed

jet carburetors,

the low idle fuel needle is also set at

the factory and normally does not need further

adjustment.

The main fuel jet is calibrated

and

installed at the factory and is not adjustable*.

*NOTE:

KT17 and KT19 engines with fixed jet

carburetors, operating

at altitudes

above

approximately

6000 ft., may require a special

"high altitude" main jet. See your Kohler

Engine Service Dealer for further information.

Troubleshooting

If engine troubles are experienced

that appear to be

fuel system related, check the following

areas before

adjusting the carburetor.

Make sure the fuel tank is filled with clean, fresh

gasoline.

Make sure the fuel tank cap vent is not blocked

and that it is operating

properly.

If the fuel tank is equipped

with a shutoff valve,

make sure it is open.

If the engine is equipped with an in-line fuel filter,

make sure it is clean and unobstructed.

Replace

the filter if necessary.

Make sure fuel is reaching the carburetor.

This

includes checking the fuel lines and fuel pump for

restrictions or faulty components,

replace as

necessary.

Make sure the air cleaner element is clean and all

air cleaner element components

are fastened

securely.

If, after checking the items listed above, the engine is

hard to start, runs roughly, or stalls at low idle speed, it

may be necessary to adjust or service the carburetor.

NOTE:

Carburetor adjustments

should be made only

after the engine has warmed up.

Kohler Carburetor Adjustment

1. With the engine stopped, turn the low idle fuel

and main fuel adjusting

needles in (clockwise)

until they bottom lightly.

NOTE:

The tip of the idle fuel and main fuel

adjusting needles are tapered to critical

dimensions.

Damage to the needles and

the seats in carburetor

body will result if

the needles are forced.

2. Preliminary

Settings: Turn the adjusting

needles

out (counterclockwise)

from lightly bottomed to

the positions shown in the chart on page 12.
