This is a nice original ignitor trip assembly for a Fuller Johnson N or K hit and miss or throttle governed gas engine. It may fit several sizes so please do your homework to be sure it fits your application. It is in excellent, used condition with no cracks, breaks, or repairs of any kind and has very minor wear on it. It fits on a 1/2 round push rod. Please measure your engine to be sure it works for your application. This assembly is ready to be used on an engine or put in your inventory as a spare. These original parts are quite tough to find in the wild or even at swap meets! If you’ve been looking for one to complete a restoration or to replace your broken or repaired one here’s your chance. The pictures tell the story. It would surely beat making one! I can be reached at 262 573 193 1 if you’d like to talk about it.
