Richard::
Sounds to me like this young fellow has fallen into the hands of people who
know little about old aircraft, and your friend is paying for their
education.
The first place I would look is the proper installation of the anti
vibration engine mounts, if they are not configured properly the engine
will rub on the mount.

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.).
