Petrol Briggs & stratton 3.5HP engine 'hunts'

How do i get my Petrol Briggs & stratton 3.5 HP engine to run smoothly, so that it doesnt ''hunt''. Have changed the air filter element for new, used new fuel & checked that the oil is topped up. It is secondhand from a friend.

Are you sure you got all the passageways in the carb cleaned out?

How did it look when you first disassebled it? Full of rust and gunk or just shellac on the surfaces?

Take the fuel line off at the carb and MAKE SURE that fuel flows freely. I have seen trash get in the tank and plub the other end up. Does it have a vaccuum operated fuel pump?

Engine not running smooth until blade is activated

ill bet this is an older briggs engine ? as they seem to need a little tlc on there governor speed control spring for it's feedback to the throttle , this makes the engine surge a bit (hunting) till a load is placed on it then it runs smooth , now if it doesn't smooth out under load id suspect a carb fuel flow problem
