Today the glow plug in my Rossi 61 RE burned out. I had failed to bring a spare with me to the field. One of our club members said he had been using the OS F plug in his high compression 2-strokes and liked the results. I had a type F with me and made two more uneventful flights on the Rossi using this plug. You guys have any feedback using the type F in a Rossi or similar type engine?
