I aquired a Jari sickle bar mower today, Thanks You. I've been looking for info on the motor. I got it and the blades all freed up. I fave a very weak spark with great compression ,I know she want's to kick over. The model # 6S , is not showing up any where that I have looked so far. Normaly I can just down load the PDF from the home sight, but even briggs and stratton can't find the model #. Any help would be appretiated.
