Hi! Patrick
I'm not 914 qualified but I'm sure I have noticed folks with this
problem before. If all the 914 experienced guys advice fails then check
out your slipper clutch. Sounds irrelevant but the purpose of it is to
iron out the impulses between the firing strokes and the compression
strokes especially since the ignition timing is so far advanced.
(assuming that the ignition timing is within the specification anyway)

Subject: Europa-List: Rough Running
I seem to be having a run of problems lately.
Having done a complete refurbishment of my 914 I have spent some time
trying
to get the engine to run smoothly, without success.
After warm up it will run perfectly at above say 4000 rpm and at idling
but
in between it is VERY roungh, The whole airframe shakes and it is on 3
cylinders at best.
I have got perfect running at high revs and have got the engine and
prop
running spot on at the recommended 5200 static. I have done lengthy
runs at high
revs (until CHT's start to complain), in the hope of clearing the
problem,
but no luck.
Plugs have been changed for new, carbs thoroughly cleaned + jets etc.,
and
fuel filters. I have now run out of ideas and would welcome any
suggestions
of where to go next.
Patrick
