We only use specially selected spark plugs, which are matched to your Generator. This is important as the thread, heat rating and electrode protrusion need to be made to the exact requirements for your engine. If they are incorrect you could cause damage to both the head and the piston. We often hear of customers who have blown their engine as they have put in the incorrect spark plug.
I couldn't believe that I needed a spark plug after only five hours of operation, but I did! After finding that I had spark to the plug I decided to buy a new one. The plug was difficult to find, but I finally found one here at a good price! It works great! Thanks!
