Haha ... I am wafting along gently on the Ester scents now. Lucia (or "Lucy" - testing the name for now) sounds happier after the filter and oil change. 7,3 litres specified ... took 6,8 litres and is ever so slightly above the maximum mark. Shall check again tomorrow once it's settled again.10W60 ester oil smells fantastic, worth the extra for that alone!
Now to chase down the last small gas leak on yon 'zoompipe setup.
