Those little Briggs have that odd way of a compression release by a bump on the back of the inlet cam thats a horrible idea, thats why the odd valve clearance 2-5, so you must not get the cam in the wrong place when going to adjust. I once just ground that bump off, this made the engine run like any normal engine, however it could snatch a bit on the pull-start but it went years after that.
