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 shut-oﬀ 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, a er 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.

Models with Governed Idle System

An optional governed idle control system is supplied

on some engines. The purpose of this system is to

maintain a desired idle speed regardless of ambient

conditions (temperature, parasitic load, etc.) that may

change. Engines with this feature contain a small

secondary spring connected between the governor

lever and the lower adjustment tab of the main bracket.
