Very nice!! Is that a 5HP briggs? Looking at your pics I cannot decide if it looks small like a 3HP. I think its the frame that its in

That's a less than 5 HP Briggs, Landuse, you can tell by the fin shroud.

I love it!

This engine was from an edger (most likely a 2hp) someone had set out for the scrappers. The recoil starter cover came off a vertical shaft mower. We had to drill the output shaft for the clutch retaining bolt.
The minibike frame is a Monster Moto 80.
The carb is from amazon

I made the manifold from the carb to engine
The clutch was from a Ct200 Coleman that we converted to a TAV30
I made the gas tank using oval auto exhaust pipe.
The exhaust pipe/header is made from 3/4" electrical conduit and a 1/2" pipe threaded section welded on
