Well its the same mount on the small briggs for ever. The 1 to 3.75 hp blocks are the same for well um about 50 years . You can run a push mower one same coil . The only big change is old briggs had a 4 post coil mount and a square coil frame the new ones are a 2 post but fit no problem . If ya need help with parts let me know got a huge book on them .
