please check the ends is bent, broken before connecting the plug.
the ends are over long or fallen off.
The connection plug must be connected tightly.
please check if the lock up is totally fixed because connection plug is with lock up.
please check if the wires are fallen off.
do not nip the wire when installing the part.
Do not fix the wire on the over heat part
Please remove the lock up when disassemble the connection plug with lock up.
Do not bend or over move the tightwire,because the bad tightwire will cause the
bad movement.

hard blow
spark plug is wet
no pressure or low prossure
no spark or weak
electrode is wet
normal
with gasoline
test the cylinder compression pressure
take off carburator after laying it down
30 min., connect to the fuel loop by
plastic tube, then blow it by mouth
spark plug is dry
no explosion
compression pressure normal
re start after put few gasoline by taking
off the spark plug
ignition test
loose the carburator screw to check if
enough gasoline inside the floater
check the spark plug again
