Spree's have CDI's (no points)...
First thing.... Buy a brand new spark plug and try that.
Next look at the lead (wire) going from the coil to the plug and carefully look for a loose or cracked fit on each end.
Next trace the wire back from the coil heading down into the motor.
Next pull apart every plug connection along the way and look for a bad connection or corroded connection.... clean them good if they are suspect ... and try them again.
From here on out it gets worse...
You need to make sure the ignition switch is actually completing it's ON circuit.
Same with the switch on the h-bar.
Next you need to remove the CDI box (on the frame.. if a Spree has one) and have the Resistance values checked from a service manual.... same with the components by the flywheel.
