Make ? nope, never saw one like it..
If it weighs only 5 lbs now it would be about 4 lbs without the flywheel and coil..Very good for a larger than 4.2 engine..The bolt pattern of the carb is wider than the later Walbro SDC and WG series used on the newer engines..Easy to make an adapter plate for a different carb...It might be a little narrower with the carb mounted right on the case instead of the angle mount....
Looks like an interesting project
