spark plugs(5,7) and exh. manifold situation

Get a plug socket with an external hex on the end for putting a wrench on. Just use it to crack it loose, then you can put an old plug boot on and back them out by hand.

Also, "used to be" Champion, and other brand name tool co's like SK, etc, had a "spark plug kit"

Generally, this had a

5/8 plug socket

13/16 plug socket, both with a hex

A 1" long extension

A 3" long extension

And a 3/8 drive, "flex head" ratchet

Here's an old one sold on eBay
