Hey, questions are no problem. Yeah nicads (1500s-3) The plug adpter was made (easily) from the stock plug. The walbro is from a Stihl trimmer a WT. (I can get the # if you need it). You must convert it to external pluse (easy) and tap the valve cover for the pluse source. the original pulse hole in the carb does not align with the original hole in the carb adapter.
