Any briggs single cylinder enthusiasts here?

[sentra]

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!!

Briggs aren't really my field of expertise sorry, @ESKIN8R might be more help.

Someone on this group might be willing to help? Unless it gives away the racing advantage....

Sorry haven't tinkered with them beyond normal servicing really. One day I might think about building a racing mower.... Won't be using Briggs though haha
