Took the plug out, rolled the bike, nothing came out the plug hole
stop.
before you do anything else, pull the head, take the cylinder off
sounds to me with no pressure coming from the plug hole that you have no compression.
id wager no rings or improperly seated rings,
the arrow on the piston needs to face towards the exhaust port
im assuming you have a kit motor
do this then come back
no excuses
do NOT try to keep starting the motor until you know 100% for sure that there are rings on the piston and that it is facing the correct way
then, blue wire to blue wire
black to black
remove white wire completely
check ground strap on magneto
solder all wire connections, not black tape or supplied connectors
change spark plug wire (copper core is best)
change plug boot
change plug
take killswitch and throw it at the neighbors cat
there is a way to adjust the clutch shaft to make it press further against the friction plate
but not yet
do the above then come back
