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. **Q: anyone have wiring for 31r7070033g1 to this motor?** A: 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? **Q: Will this replace a Model # 31C707-0230-E1 in a Craftsman Tractor without any modifications?** A: 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. **Q: replacing CV14 kohler engine - muffler vents to back, muffler too big. will not allow mower stand/bagger won't work.. how to use /get side muffler?** A: Ours had a side muffler. I cut the side of the cowling to allow exhaust to escape. ## Frequently Bought Together - Briggs & Stratton 31R907-0007-G1 500cc 17.5 Gross HP Engine with 1-Inch by 3-5/32-Inch Length Crankshaft Tapped 7-16-20-Inch - HIPA 595304 Ignition Coil Magneto Armature for Briggs & Stratton 591459 799650 592841 795315 490586 492341 798853 495859 17HP 17.5HP 19.5HP 20HP Intek OHV Engine - Briggs & Stratton 692003 & 692011 KIT (Intake & Exhaust Push Rod Set) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/3154772-31r907-0007-g1-500cc-17-5-gross-hp-engine-1](https://www.desertcart.sg/products/3154772-31r907-0007-g1-500cc-17-5-gross-hp-engine-1) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-12*
