Are you sure about that? It is my understanding that ASTM does not have a IFR standard, and until they do, no new SLSA can be IFR certified. Certified engine or not.
A builder of CH-750 can write proper limitations, I think.
I was speaking of factory built SLSA aircraft only. When you are talking experimental the engine does not need to be certified for the airplane to be flown in IMC.
