They finding a Briggs model # starting with 28/31/33. 14-21 hp sticker. There's lots of aftermarket parts for them.

Besides the shorter stroke and smaller cc head you basically have a 28. +/-  Built a few couple years back when USLMRA made them legal.

I'd really like to be part of some real racing but I can't find  any near me .I live in panama city florida ,mud bogging is a big deal down here so I figured I'd build my mower for the trails and the pit .I want to be safe if I take the gov off
