Briggs Flathead / Re: 22ci vs 25ci vs 28ci bore stroke and rods?

what i have found is that the 25" has a crank with a 1 5/16 throw. and the 28" has a throw of 1 17/32. the throw is from centerline to max arc. so stroke should be twice that.
you can put your model # of each engine in your search bar on internet and it will find a pdf file for your engine with all parts and parts #'s. do the same with the part # and you should find more info about it. like the crankshaft.
