Follow these steps in order to determine the cause:
1. Is there fuel in the tank?
2. Is the kill switch in the ON position?
3. Is the choke lever in the proper position?
a. ON for cold engine or OFF for warm engine.
4. Is it flooded? If you smell gas fumes, this may be the problem.
a. Follow the steps on page 13 in this book to remedy.
5. Is fuel getting to the carburetor? Check for clogged fuel line.
6. Remove and inspect spark plug.
a. Is it fouled? Replace.
b. Is it dirty or caked with residue? Clean or replace.
7. Spark Test:
a. Put the spark plug back into the boot without installing in
the engine.
b. Holding the rubber boot very carefully, place the open end of
the plug onto a metal part of the engine and pull the starter while
watching for a spark. If there is no spark or a very faint spark, replace
the spark plug.
Be very careful not to touch the metal part of the spark plug as you
can receive a painful shock.
Be sure there is no spilled fuel in the area of your spark test.

A fuel leak on the back of the engine around the
carburetor could be caused by a stuck float. To check
to see if this is what is causing a fuel leak that you
have noticed, tap the float bowl (located under the
carburetor) with a screwdriver a few times to
dislodge the float. If this does not fix the problem,
turn the fuel valve off and call Motovox.
1. Check for proper choke position.
a. If the engine is warm, choke should be OFF.
2. Clogged carburetor jet.
a. Consult with your Motovox Service Center.
3. Bad or contaminated gasoline.
a. Drain fuel tank and refill with clean fuel from a clean container.
