I made this little discovery yesterday when I went out to start my 15 year old 5hp B&S tiller. It had been running fine with the exception of a
little smoke, but when I pulled the cord, it suddenly froze in place, and I just about broke my wrist. Note: Don't hold the starter cord handle too
tight. You can really hurt yourself if something like this happens. My wife heard the pop of my wrist bones across the garden!
: The piston rings had seized up, and would not allow the piston to travel freely against the cylinder wall.
: I removed the cylinder head and squirted some duralube around the piston, allowed it to soak in a few moments, then took the wooden
handle of my hammer and gently tapped the piston all the way down. I then wiped down the cylinder walls to remove any grit or metal shavings, rubbed
on a little more duralube with a clean rag for lubrication, then slowly pulled the cord to see if the piston moved freely.
: After replacing the cylinder head and cleaning the plug, I pulled the cord to see if it would start, and it did. I got the whole lot
done without ant further issues. I doubt it's a permanent fix, and will probably need to be done again, but hey!, I got my ground tilled up, and
didn't have to spend another for or five hundred dollars that I didn't have for a new tiller.
I really need a new tiller, but I plan to get every hour of work I can get out of this one first!
