1. Intake Manifold Inspection - Check the intake manifold for leaks.
Is there a leak in the manifold?

Yes - Loose carburetor mounting bolts
- Damaged insulator/spacer
- Damaged intake manifold gasket
- Cracked or broken intake manifold/pipe
If “YES” - See your Authorized Monster Moto Service Center to have your go-kart serviced.
2. Spark Test - Test for ignition spark by removing the spark plug and inserting it into the spark plug cap. Place
the open end of the spark plug on a metal part of the engine and pull start the engine. You should see a nice
blue spark on the end of the spark plug. A faint spark will not start the engine.
Do not touch the spark plug or plug cap while pull starting the engine. You will receive an
electrical shock which could result in serious injury or death.
Is there a good spark?
No - Fouled or faulty spark plug
- Broken or shorted spark plug wire or spark plug cap
- Faulty or shorted magneto assembly
- Broken or shorted engine stop switch
- Loose or corroded wires and/or connectors (always clean bad electrical connections)
Yes - See your Authorized Monster Moto Service Center to have your go-kart serviced.
