Hey Darick: There are additional changes that need to be made. One is that
you need to split the bottom cowl in to two pieces. This allows it to be
removed without removing the exhaust. I have had problems with the exhaust
gaskets fitting properly due to being slightly too large. I have seen engines
with the oil tank filler neck on the RH side instead of the left, and I do
not know if this will cause any interference or not. Continental made the
tanks different because of different aircraft configurations, and over the
years some of these have been incorporated on our Ercoupes.
I was originally working with Lee of Skyport (when it was owned by
Champion Aircraft) and we had a three page set of directions on how to make
the change. However, with my computer failures over the years, I have lost
those original directions. There was initially an error made in the amount of
down sweep in the LH exhaust. That is why Don is fitting this set to make
sure that the change has been made so the pipe will clear the engine mount.
I believe another problem that was encountered was that during a top
overhaul, the exhaust flange of a cylinder may be cut down in order to
produce a flat surface to mount the exhaust on. This changes the angle the
exhaust fits on one side or the other, and causes the exhaust to leave the
cowling at a different position. So if you have new or used cylinders on your
engine, you could encounter a problem with fit of the cowling.
