if you ever have one to lock up and it doesnt break the connecting rod you can usually unseize it or about 5 bucks. go to the parts store and get a can of liquid wrench, take out the plug and fill the cylinder full of liquid wrench. replace the plug. in 2 or 3 days take out spark plug and fill it up again. replace spark plug. in about a week you should be able to turn the engine over with the pull crank, if not take a pipe wrench and easily turn the vertical or horizontal shaft clockwise. it should break loose and you should be able to crank it. you can also use diesel fuel but the smell gives me a headache and i dont have an extra can to put it in.
