will this replace model 31f707 o112E1

First check the bolt hole pattern. If that matches then check where the exhaust exits to make sure it is the same. Finally check the charging circuit. There are two types, a dual circuit which is usually an older motor an a tri circuit which is a more recent type. This is critical as damage to the alternator and regulator can occur.

anyone have wiring for 31r7070033g1 to this motor?

Have you found a wiring diagram? If so, please post. Mine has a grey and black wiring, but I don't know what it attaches to. I'm replacing a 13 hp B&S that totally failed (cylinder exploded). I can't get the new one to turn over yet. I've had it for about 8 months, but just now had time and need to install. Any thoughts?

Will this replace a Model # 31C707-0230-E1 in a Craftsman Tractor without any modifications?

I swapped the same engine as yours and had to reuse my old muffler and needed to modify the alternator wiring to go from dual circuit to this 9 amp regulated. I searched for Briggs Stratton alternator repower guide pdf and purchased a 692306 wiring harness to make the swap easier.
