too funny.
just today i discovered that the hear riser on my 50 is stuck closed.
looked at a bunch of your pics denny to get a better idea of how it is supposed to look. can't seem to get it un-stuck so i may have to take the intake/exhaust manifolds off to get into the space and free it up.
not sure i really need one here in arizona but i should make it right.
sepp, here is a link to some reference shots of the heat riser.
