Has anyone tried this spark plug socket on a 610? This one looks like it might work OK. It has part number 6899 on the side, normally for GM vehicles. That narrow spot in the cylinder head fouls on all of the standard 5/8 plug sockets when I try to remove the socket. 2 broken ceramic parts later and I need to find something else. I am not fond of the swaged tube style that Husky supplies as OEM and besides I did not get a tool kit with mine anyway.
I'd go to Autozone or some other parts store that lets you try tools for just a second, and see if any of their deep sockets will work.
