The 5hp engine had a lighting coil but you will need the correct block with the bolt bosses under the flywheel,the longer electric start crankshaft,the taller blower housing for electric start,the flywheel with magnets under the where the points would normally go,and the lighting coil itself.
These parts were mostly used on generators and some parts can be had from snowblower also.
