Repowering a log splitter - need help identifying a suitable Honda engine

Want to replace an old Briggs on a log splitter.  Looking for a Honda engine with: 1) Crankshaft PTO size: 7/8" dia x 3-5/32 long, 2) Heavy flywheel, and 3) controls (on/off switch, choke) on the engine.   The Honda crankshaft code is N1 per their website, but I cannot find anywhere to decode a full engine part number so I can order one.  Thank you for looking.
