Sure. It's just the bigger frame, 305 or 318cc. Same height as a 5hp Briggs.
Points vs electronic, 1.187 or 1.375 journal.
Porting, tight quench, a little more timing, carb/pipe, same as any other.
The Motorsports starts off with some nice parts, but the 60% displacement advantage is tough to beat.
They're sorta wide. VKE billet side cover gives more room.
