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.
