I have a Ryan LA28 aerator that is probably around 20 years old. The engine is a kawasaki FE 250D. I was having trouble keeping it running. My local small engine repair shop said the problem is the coil igniter. We have tried to find the correct part but the kawasaki web site says that this part is no longer available and there is no replacement part. The part number is 21119-2143. I have been calling dealers but no one seems to have this part. Does anyone know of another place that might carry this part either new or used or any replacement part that could work?
