I hit something hard and believe I damaged the governor. The numbers on this motor are 6006-23:44 D26. It’s a 15 yr old Poulenc.That number comes up nowhere on Google or in parts search’s.or I’m doing something wrong. I need a service manual for guidance on this issue. Do I just pull the motor off the mower and pull the bottom cover to access the governor? I haven’t identified the part or engine positively yet so I’m reluctant to do anything without out a proper manual. If anyone can cross that engine number ar suggest a generic manual for a 15 year old b&s lawnmower engine it would be of great help. As always, thank you in advance.
