Yes, you are correct in that statement.
I build racing engines for a living, and perhaps went a step
further than was necessary.
Regardless of any hearsay, the dyno speaks truth.

///////////////////////////////////////////////////////////////////////
I have built racing engines too. In fact I built one that won the Firecracker 400
at Daytona back in the mid 80's, before it was called the Pepsi 400. I have
also worn out several dyno's so I didnt just fall off the turnip truck either.
I did call Lycoming and politly asked for the specs and their response was "
we don't have that kind of information". That's the main reason N801BH has an
all aluminum 347 cu in Ford in it. Those guys at the certified end of aviation
are shooting themselves in the foot faster and faster. Detroit diesels 71/53
series have had roller lifters since the late fourty's. Just last year one of
the Lyc clones announced they had a breakthrough and now incorporate roller
lifters in their premium line of engines. Geez...... they are only 50 years late
!!!!!! I am sure Archie has wondered too why they didn't come up to speed decades
ago. Thank god for the homebuilt movement and alternate powerplants. I
will take the feedback from one of the posters and ca
ll Lycon, I am betting they will have the numbers I am looking for to degree the
cam and check the compression. Thanks again to all who have answered my post.

Use a rawhide mallet or rubber hammer.

I am trying to remove the oil sump and accessory case from a Lycoming
0-235.
I took out all the bolts but the gasket is holding it together pretty
good.
Does anyone have any techniques for causing it to separate without
scoring
the mating surfaces?
Joe.

If you can get some small safety wire in between the gasket then wrap to
pieces of wood as handles around it and pull it through the gasket. If
you have a rubber or rawhide hammer hit the case on the flange all the
way around, and hit it with good strong blows...

I tried that with a leather mallet (a sledge hammer with a head like a
dog
chew bone). I didn't hit it very hard for fear of cracking the housing.
I
figured I should ask the experts before pounding away like a cave man.
I was wondering if there was a secret kung-fu pressure point to aim for.
Or
maybe a Lycoming pry apart tool #2o02587a9sa87.... .
My next attempt would be to try to delaminate the gasket with a single
edge
razor blade. Any suggestions?

I am working on a Steme motor glider with the Rotax 914 f engine, The
problem is that on start up
it with full choke it will just die after warmup when the choke is pulled
off. After it warms up it may
start without the choke but does not develop full power. I only seem to get
about 75 percent in climb
Does anyone have any expert advise on these motors?
Thanks
