Battery Charging

WARNING: Explosive Gases!

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 away 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.

NOTE: Do not apply 12 volt DC to kill terminal of

ignition module.

Fuel Filter

Some engines are equipped with an in-line fuel filter.

Periodically inspect the filter and replace with a

genuine Kohler filter every 200 operating hours.

Carburetor Troubleshooting

and Adjustments

Kohler MV16,18,20 engines are equipped with one of

two basic types of Walbro carburetor–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: Engines with fixed main jet carburetors,

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.

• Make sure fuel is reaching the carburetor. This

includes checking the fuel shut-off valve, fuel tank

filter screen, in-line fuel filter, fuel lines, and fuel

pump for restrictions or faulty components,

replace as necessary.

• Make sure the air cleaner base and carburetor is

securely fastened to the engine using gaskets in

good condition.

• Make sure the air cleaner element is clean and all

air cleaner components are fastened securely.

If, after checking the items listed above, starting or

engine operation problems continue, it may be

necessary to adjust or service the carburetor.

Walbro Carburetor Adjustment

In general, turning the adjusting needles in (clockwise)

decreases the supply of fuel to the carburetor. This

gives a leaner fuel-to-air mixture. Turning the adjusting

needles out (counterclockwise) increases the supply of

fuel to the carburetor.

NOTE: Carburetor adjustments should be made only

operating at altitudes above approximately

1830 m (6000 ft), may require a special "high

altitude" main jet. See your Kohler Engine

Service Dealer for further information.
