Make sure its a cast iron flywheel, folks do replace the cast iron with aluminum so this may have been done years ago. Second valve tappet clearance with piston just past top dead center on the compression stroke (intake valve just closed) should be about .007 intake or .011 exhaust. Check tappet clearance in that little box hole where the valve springs are. Make sure the intake valve and spring has not accidently been swapped with the exhaust valve and spring(they are different and have different specs/metals).

Hi, I also have a Briggs & Stratton 5HP that is brand new, but the problem is the same - when I try to start it, the cord pulls back significantly, so I'm not sure what's wrong.

Remove the head and check for excess carbon. This can lead to high compression ratios causing harder starting slash rope pulling.
