Good morning, firs of all sorry for mi english... I am from Argentina and I need your help. I receive a new pouland tractor with a B&S 17 hp ohv. The owner who give me the machine, mixed by error the push rods (they are different). I need to know two things: 1) wich valve is at the top and wich at the bottom 2) wich rods I have to install at top and wich at bottom? Thanks for your help...:thumbsup:

17 HP will probably be a model 31 or 33.
Exhaust valve is top and inlet is bottom.
Usually inlet has the alloy push rod and the exhaust has the steel push rod but on this model it can be the other way round.
