I too have a 2011 Victa Mustang VEX160 2 stroke, which has in the last 3 weeks decided to lie down and die. No spark. I removed the ignition coil (MA05697AZ with built in module) after some troubleshooting and took to the local mower shop, where they tested the coil and reported that indeed it was dead. My multi-metering found resistance around 14k ohms. My neighbour volunteered a coil with separate module (MA05556A), which has resistance around 6k ohms. It will physically fit in place. Bolt holes match. I plan to install and give it a go. My question: Can the module be mounted on the sheet metal cover below the crankcase air box, perhaps temporarily for trial, or must it be mounted outside/inside the lower crankcase housing. This will necessitate drilling and tapping two small holes in the casting. I'll attach a couple of photos of original coil and temporary replacement. Still like to get hold of a coil with built in module, as in agreement with a comment above, the mower has been an excellent starter. First pull every time!
