Dumb Question

[Rustychopper]

whats the socket size for the spark plugs and is 14 or 20 for the torque?

 

[pa23driver]

my 13/16 spark plug socket fits like a glove and the manual calls for 10 - 18 ft.lbs. aka tight enough, but not so tight you strip the threads

13/16ths or 21mm
Aluminum Clyinder Head Flat seat type (with gasket)
Spark plug type 14 ø mm plug 11.0 - 18.0 lb-ft.

I find 14 ft-lbs works perfect. I also turn the plugs in by hand so that there is no chance of cross threading.

I saw a guy use an impact wrench to put them in. Didn't over tighten them, just cross threaded them so bad the heads were done. He was my metal shop teacher in high school. He was not very smart.
