Re: Briggs Engines Horizontal vs Vertical
- Sure, Gnat
A Briggs V-twin horizontal will easily convert to vertical by
welding up a sump and pickup with a freeze plug and pressing it into
the vertical sump hole. You will also need to weld up a new manifold
for the flo-jet, keep it to 7.5 inches. There is just barely enough
oil mist available in the new configuration to lube the valves so
outside oilers to the valve covers would be nice. Mount the prop on
the flywheel end or you will be sorry. This means lathe work for the
hub. The now horizontal shaft will mount to the firewall easily
using the original tangs and whatever lord mounts you need. Use an
oil pressure guage to check out your work, 50 lbs psi @ 3700 rpm.
NEVER EXCEED MAX REVS. Bendy valves and worse will result. Other
than that the Intek is pretty robust and thrifty...just not terribly
useful except for a strict FAR 103, and slow at that.
And of course, never modify this engine for performance. It is
just a big (80 lbs) lawnmower engine and should be respected for that
or else you will be on an expensive, slippery slope that will end up
with in pile of broken parts. CC

- Clair, can you tell me if all the overhead briggs use a oil pump to
lube the rockers?....Ted
