I thought of riveting it to the air baffle plate which is sandwiched between the engine block and the mower deck. I was just trying to avoid modifying the engine block..
I'd avoid putting the module on the inside/on the baffle plate as there is so much grass and dirt / dust that the fan sucks in ,the coil
has to be in there but best to mount the module on the outside casting it can also still get a lot of grass around the module on the outside but is easily cleaned away with an air compressor and air gun when it's under the carby.
Cheers
