Hi Dennis
Looking at the IPL of your engine, it appears to have the metal shielded spark plug cap (B&S part # 793351) on the end of the plug lead. These caps seem to fail quite often, so I keep 3 in stock. The cap will pull off the end of the lead, you may need to spritz a little silicone spray lube between the rubber cuff and the lead in order to get it off. Once you have this cap off, repeat the spark test directly on the end of the lead. If you have spark, replace the cap. You can test the resistance of the primary and secondary windings, but there's no way of checking the trigger coil or the switching transister. Primary winding resistance is usually 0.5 to 3.0 ohms and secondary winding is usually in the 3,000 to 7,000 ohms range. If you need a new coil, B&S part # is 590454. Hope this points you in the right direction,
Sky
