My B & S engine is a 5 hp and different entirely from that one... Heck, I coulda got that guys flywheel off easy... He don't know nuthin' about pullers... Using an impact on that is stupid... All ya' gotta is crank down about 15-18 ft pounds of torque with the puller and tap the side of the flywheel with a ball peen hammer a couple times to agitate the molecules and it would have popped right off...
