I have a hustler mini z with the 19 kawi. The other day I lost power under laod. It will idle fine but and load in bogs bad. I put in new plugs, fuel & air filter and pulled the carb disassembled in cleaned still the same issue. So with it running I pulled the plug wires. Inboard one came off motor died, outbard one came off no change. I'm think coil. Can anyone confrim for me?
