piston hitting spark plug

I figured it out yall. Spark plug lost the compression washer allowing the plug to screw in too far. Thanks for all the help

Oh ****... the most obvious thing is the easiest to overlook lol.
How did it lose the washer... those are pretty much on there if you know what I mean.
 
Nice lol, I think the 12yc is the same as NGK's BPR6ES, if your gunna get a new plug get that one , my engines usually run better with the BPR'S
