4 Hp Briggs and Stratton Engine, was running last season before I took it off the rotting deck. A tune up and carb cleaning should do it. The only thing that could be a problem is that the mounting bolts broke off while removing the motor from the deck, so you would have to remove them to mount on your deck. A little heat and locking pliers should do it. Wish i could fix but dont have the time. Asking $20 Thanks Nick 508 493 0518 Location: Swansea Ma it's NOT ok to contact this poster with services or other commercial interests rhodeisland
