I don't know much about this, but why can't you take a system from a engine of the same size and adapt? It seems to me the injectors or computor wouldn't know the difference. The mechanical part of adapting shouldn't be to hard. The timing could run off of the crank, I have seen 5HP B&S with crank trigger timing. The rest of the sensors could be mount easy enough. Its going to take somebody with a understanding of the computor to make it work. Just think how cool it would be! New hood emblems
