Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Well, I think I may have a nice scrap Honda Engine on my hands....While doing my yearly maintenance on all my OPE, I turned to the last remaining piece of equipment needing attention.  I removed the spark plug from the engine, and inspected the plug and all appeared to be fine.  Upon trying to reinstall the plug, I met more resistance than  usual when installing a spark plug.  I backed it out and then tried to thread it up again and made it a little further past my prior point, but then again hit more resistance than I thought I should when installing a spark plug.  Upon further inspection, I notice some metal shavings and that I had managed to strip a very nice engine with an expensive NGK spark plug.   Is my powerwasher shot?  Do I need to install a new head?  Is this something that most dealers could fix for me?  Any advice would be appreciated.  Would I be able to tap the threads?  If so, how would I clean the metal shavings out of the engine? 

Thanks.
