help identifying 2 stoke

#1
I wasn't sure if I should post this here or in the engine section but this is on my unidentified bike. It has no markings besides a I'd tag with just a number on it. And the recoil handle says briggs but ik that realy don't mean anything. 20160226_195416.jpg 20160226_195341.jpg 20160226_195330.jpg 20160226_195242.jpg
