Bo Eklund (member in Sweden) correctly identified this motor as an Archimedes circa 1913.
The carbs are not original, as pointed out. Interestingly enough, some photos of this motor show a single carb mounted in the centre of the crankcase with a cover plate over the intake port on each cylinder.
It appears that this motor would have used a simple mixing valve not unlike those seen on the Evinrude motors of the day, so putting it back to (be closer to) original would not be impossible.

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
