Yes, I had a similar problem but not as bad as yours. I took an hour or two to
reduce/smooth the fitting surfaces to get the front port side to fit. I think
it is now OK but I haven't tried to remove it yet and the plane hasn't flown.
A further problem that I have is that the captive flanges and studs have
distorted
when tightened to 177 lb in. I posted a message about this a week or two
ago but it didn't appear. Discussion with Graham Singleton and Kim Prout
suggested
this is a common problem with the Mark 1 Classic and I understand that there
are some special locking bolts available that prevent loosening when tightened
to lower torque settings. I intend to give them a try.
The exhaust systems appear to be a Europa weakness. My original mild steel
system
did not fit. Europa wanted to cut the tubes and re-weld them. I was unhappy
with that and ended up having to buy a new stainless system (at only a very
modest discount!). Unfortunately, all the SS systems in their stock were faulty
and it took several weeks to get all the parts. I now await their comments on
the
distorted flanges and studs.
The moral of the story? - do your own quality control because Europa and their
supplierss seem to have some problems in this area.

Just a 'trawl' to see if others have had similar problems.
I bought a new stainless steel exhaust system for my 'classic' and found
that the stub pipes were tight. One so tight that I couldn't get it out
again. Luckily I was workshop fitting it and it wasn't on the 'plane,
otherwise I would have been in real trouble.
I decided that it was Europa's problem and took it along to them to get out.
They ended up by cutting it out as all other attempts failed. All the stub
pipes are a very tight fit and only go 3cm into the sleeves at best, whereas
the full fit available is 5cm. At 3cm I don't think the springs will fit as
the distance between the lugs is too long.
Also, all the pipes are slightly oval which exacerbates the problem. I am
having to try and make the pipes fit by working on the external and internal
diameters as I cannot imagine I will be able to fit the system on the
'plane, especially as the silencer has to be joggled onto the two stubs from
the rear cylinders in particular.
Has anyone else had a similar problem? I have to say that the original
non-stainless system fitted fine and is only being replaced due to
corrosion - shame!
Happy days,
Peter Davis
