Sears 8hp rotospader engine mount plates can possibly be used to swap any standard 5hp Briggs kart to a bigger 8hp Briggs engine. Flathead bolts go through the rotospader plate into the 5hp karts engine mount slides. Then flathead bolts up through the rotospader plate that match the 8hp engine mount pattern. This setup should allow you to keep the slides on the original 5hp mount for proper chain tension. No grinding the 5hp engine mount out or welding to it. Picture of the rotospader I got the conversion mount from. Is it even spaced correct to move the 8hp engine over for the 30 series??
