318 is hard restarting after running 20 minutes or more.

My well cared for 318 is hard restarting after running 20 minutes or more. Fresh gas with sea foam and clean gas filter.
Prior to the last oil change, I added the proper amount of sea foam to the oil and then drained it.
Should I pull the plugs a give them an eyeball or just change them?

You're due for a valve adjustment if its never been done. I'd replace the plugs and see what happens its cheap and if you don't know when they were last changed its not gonna hurt :fing32:
