Richard,
The nose bowl is made of dead soft aluminum, and can be gently
pushed back away from the prop. Adding a spacer behind the prop is not
a good idea, since it will probably increase engine vibrations. It is
also not legal. I don't think that cutting back the cowling rails is a
good idea either.

Ercoupe Guru's. I have a young fellow in the hanger next to me who
also owns an ercoupe with a 75hp continental that has been majored
with new millennium cyl.pistons, rings, push rods etc. The aircraft
has been a thorn in his side expense wise. The aircraft has been in a
repair shop for over a year, wings off, all center section rivets
electronically checked, main fuel tank leak repaired,. tail section
removed, cleaned up installed with new bolts. Other repairs as
needed.The engine installed with new millennium cyl. Test flying shows
a vibration level that is not acceptable. He has tried the prop in
different positions to no avail. this was none at a dynamic balance
shop. I think he said he had a figure of 1.7, the mechanic said that
was high and the best he could do.Needles to say he is at his wits end
over this.He has talked to several aircraft mechanics about this
problem, and no one has been able to solve this problem yet. He also
has a clearance problem with the nose bowl protruding too far forward
rubbing the prop, a aluminum spacer was added to maintain clearance. I
guess my question on this issue is can one cut back the cowling rails
with out running into other problems. This is not an isolated problem
as I have some propeller marks on my nose bowel that dates back
sometime in the past. I guess my question is has anyone run into this
problem before and the cure. Sometime as individuals we may not be
able to solve problems, but bringing a group knowledge base together
can. Thank you in advance for my friend Richard L. 3041H PS. I would
loan him my prop to try but I have a 85hp with a 71-48.

The "dash" numbers always confuse me. Isn't the -12 the engine with
the
vacuum pump? I thought we had the -8 but it's early and I haven't
fully
awakened.

I'm looking for an STC or 337 for installing a C-85-12 in a
415-C? Can
anyone help?
Ed,
I believe that no 337 is required. Refer to the type certificate
for the
415-C (A718 Item 110.).
