AMC's Engeneering

The other day when I went to change the spark plugs and check compression on the 196 in the Rambler, I stuck my 13/16" socket on #1 and was supprised it didn't fit.. looked down at it, and the plugs deffinetly take a 13/16" so I tried again, still no go.. I then realised that the resess holes for the plugs are too small for a standard socket to fit.. I had to go down to the auto parts store and look in there lawnmower section and get a T handle lawn mower spark plug wrench, because they are very thin walled.. worked great...

also. I was looking through my TSM, under tune up it gives valve adjustments... it's running a Solid cam... 8-12k miles it says to adjust the valves.

Some sockets are thinner walled than others, like SnapOn. It seems the higher quality ones rely on the grade of the steel rather than thick walls to make them strong. I keep a 5/8 and 13/16 in SnapOn just for that reason, like getting by headers and recesses.

I have a mix of socket brands. I don't remember what brand of 13/16" it was that I grabbed. could have been a Stanley or a Task Force most likely. but I also have a set of Pittsburg steel ( Harbor Freight ) thrown in the mix too.
