sentra Posted April 7 Share Posted April 7 All the racing lawnmower forums are dead these days, I’m trying to determine if the crank, cam and lifters on briggs flathead 28 is interchangeable with the 28 ohv motor, all the info online is for flathead- maybe because of their class rules? there is one comment I can find that suggests that it is, if this would be convenient as there is a billet flywheel, crank, cam, rod & piston available for the flathead motor and I have some ohv motors onhand. (The non avs early kind) Trying to end up with a light weight air cooled 500cc vertical shaft motor that will do 5500-6000rpm for my amphibious boat thing, currently using a 200cc and it’s a little underpowered and it makes me nervous turning the pot metal flywheel so fast. I guess the other way is to find out if the 28 flathead is common in nz, Shiloh?? I forgot your username to tag you!! Quote Link to comment Share on other sites More sharing options...
