Small Engines (Lawn Mowers, etc.): small motor, wd 40, hp motor

Question
3.5 hp motor for my canoe,mercury, I do not have the manual. Used it a few times. looks new. always performed perfectly. Have not started it in 12 months. Now the rope will not pull at all

Answer
OKAY, THIS ONE WANT TO BE STUBBORN.  CONFIRM NUETRAL AND TRY PULLING..THIS ELIMINATES LOWER UNIT JAMS.  OKAY NOW,
REMOVE THE SPAK PLUG.  TILT MOTOR UP AND SPRAY WD-40 INTO THE CYLINDER FOR QUITE AWHILE AND LET IT SET FOR SEVERAL HOURS.  TRY THE PULL ROPE AGAIN...IF NO GO THEN REMOVE THE MOTOR AND COWLING THEN STAND THE SPARK PLUG UP AND POUR A PINT OF DIESEL FUEL INTO THE SPARK PLUG HOLE.  LET IT SET TWO WEEKS.  EVERY THREE OR FOUR DAYS TRY TO TURN THE MOR OVER BY THE FLYWHEEL.  IF BY THE END OF THE MONTH THE MOTOR IS STILL SIEZED UP, THEN IT WILL NEED REBUILDING.

GOOD LUCK,
GEORGE
