The steps below are provided to you by us, in order to facilitate self-help steps to getting your scooter, atv, moped, go kart or utility vehicle running, if it doesnt fire up out of the box, or you need a good understanding of all the components involved in making your machine run correctly and consistently.  All machines require three elements to run:

1.  Fire (or spark):  This is the electrical charge created by the electrical components of the machine that send a spark to the "spark" plug.  This spark ignites the fuel.  All electrical components (to include "kill" switches) must be functioning correctly in order to complete this chain.

2.  Gas:  We all know this is self-explanatory, and is the source of combustion within the engine chamber when the spark ignites, creating the power to run our machine, or make it go.

3.  Air:  Again, self-explanatory.  Air mixes with the gasoline as it is drawn through the carburetor and sucked into the combustion chamber of the engine.  The correct amount (mix) of air and fuel is critical to correct combustion within the engine chamber, otherwise you're looking at a mixture that is too lean (not enough gas) or too rich (too much gas).  Either one of these extremes will not allow your engine to run smoothly and efficiently.  (e.g., rough running, missing, etc)

Please review the link below to ensure you've done all required steps in the engine startup and running procedures.  If your engine runs correctly "out of the box", it is suggested that you make NO carburetor adjustments, but please feel free to familiarize yourself with the rest of the machines components.  While all the information contained below does not apply to ALL machines, some/all is applicable to EVERY machine.
