[QUOTE="jaguar, post: 1468736, member: 19340"] It can spark outside the engine in normal air pressure but not spark inside the engine because the higher the air pressure the higher the voltage needs to be to create a spark. Some old flywheels lose magnetic strength which lowers voltage to the CDI. Also any rust at any electrical connection of the ignition system (sometimes even a screw holding down the stator plate) can act as a resistor and lower system power. But if you lower the compression with an extra head gasket and bump start it going fairly fast (two people pushing hard) it should start but then die if you let the revs get too low. Only real solution then is to change the magnetic flywheel. [/QUOTE]
