LaSwamp, the spark plug is a challenge to access. It looks easier than it is. I took the Torch plug out last night and got the NGK this morning. I'm going to see if using a 5/8 spark plug socket with small channel lock pliers on the flat sides of the socket makes it easier. I dropped the plug into the gen removing it. That was nerve racking

. I removed the side panel and still had to shake the gen while upside down, the plug thankfully finally fell out and I hadn't yet filled the oil or gas in the gen. The electrode and porcelain are shiny sooty black. Which is strange because the gen has no signs of ever being run. It doesn't smell like gas or oil. I don't have any 10W-30 conventional oil, only an old orphan quart of 5W-30 Shell Formula conventional oil. I think that should work ok for short break in runs with frequent oil changes to get any metal out. After 3 or so changes with the 5W-30 I'll then run 10W-30 synthetic. One quart will give you 4 oil changes. Hopefully Sunday I can take pictures and get the gen running to start the break-in.
