Help ID this carb!

Hi, just got a minibike with a 3.5hp Briggs. However, the carb is not briggs, but the manifold bolts up to the engine.

I can see "KUNI" and "corp on one side, and "made in Japan" and some Japanese characters on the other side. I wanna think it's a old Mikuni but the M and I are cut off, and can't find any online with the round float bowl like this one...

I need help finding a new bowl o-ring, gas leaks like crazy.

I have no real idea what it is..but...
Typically if the O-ring is a regular shape... Pretty much any auto parts store should have a selection of O-rings to look at and see if any fit...
Some I can imagine will have o-ring stock to make your own...

Is that off a Briggs and Stratton Diamond power engine? The first generation of flatheads after the Pulsa-Jet era had bowl type carbs like that. It could well be original. Have you looked up the parts manual using the engine ID# yet? Jack's small engines should have full exploded views of just about everything.

No, it's a modern 3.5, pictured below on he left. However, it's been kinda neglected, but still runs nicely
