Thanks for the tips TopEndTorque,
It is absolute magic and I am totally happy with my recent purcase. Its funny how so many people assume I bought a Robinson. I have 1 hour in a Robbo and its not increasing. I just love the 47 always have! I love the noise too but I must admit to having heard nearly enough on day 7 at Oshkosh with two 47s flying overhead dawn to dusk doing joyflights.
Can Robbie owners claim similar enjoyment with a R22/44? I suppose they take a lot less greasing but I dont think they have the timeless looks of a classic like the 47 or 206.
Now to find the magneto idle gear shaft.
I will look for a drip of oil there when I find it - but how clean can one of these engines be anyway?
It does have a wet sump but there always seems to be some oil sprayed around near the dipstick and around the intake manifold. It could be just drops from the bottle when filling. Wish it had the seperate sump! But cleaning does make me inspect quite well.
Next question ... how to polish the bubble and keep it clean?
