Basics:
* Spark Plugs: Double-check the spark plugs are the correct type for your Banshee (NGK BR8ES) and properly gapped at 0.028". Are they brand new?
* Spark: Make sure you're getting spark. Remove a plug wire, hold it near the engine block, and ground the end. You should see a blue spark when you kick or crank the engine.
* Fuel Delivery:
* Fuel Lines: Check if the fuel lines are kinked or blocked.
* Fuel Filter: Make sure the fuel filter isn't clogged.
* Fuel Pump: If you have an electric fuel pump, ensure it's working. On older Banshees with a mechanical pump, make sure it's properly connected and primed.
* Air Intake:
* Air Filter: Clean or replace the air filter.
* Airbox: Make sure the airbox is connected and not restricted.
Ignition System:
* Timing: Double-check the timing was set correctly during the rebuild. Refer to your service manual for the proper timing marks.
* Ignition Coil: You mentioned a new coil, but ensure it's correctly wired and the connections are tight.
* CDI Box: A faulty CDI box can prevent spark. While you have a new one, make sure it's compatible with your Banshee and is wired correctly.
* Kill Switch: The kill switch can sometimes be the culprit. Make sure it's in the "run" position and not stuck.
* Wiring: Inspect all wiring for loose connections, shorts, or broken wires. Make sure the wiring to the CDI box, ignition coil, and kill switch is intact.
Other Possibilities:
* Valve Timing: Ensure the valves were timed correctly during the rebuild. Improper valve timing will prevent the engine from running.
* Compression: Check the compression of the engine. Low compression can prevent the engine from starting.
* Carb Issues: If you have carb issues, like a clogged jet or a stuck float, it can prevent the engine from getting fuel.
Troubleshooting Tips:
* Start with the basics: Always begin with the simplest things, like checking the spark plugs and fuel.
* Use a multimeter: Use a multimeter to check for continuity in the wiring and to test the CDI box and coil.
* Consult a service manual: A service manual will provide you with detailed instructions on how to diagnose and repair your Banshee.
* Seek professional help: If you're still unable to get your Banshee to fire, it's best to take it to a qualified mechanic.
Important Note: Always be careful when working on your Banshee. Disconnect the battery before working on any electrical components and be aware of potential hazards.
Good luck! I hope this helps get your Banshee back up and running.
