The mog is suffering from a touch of the winter flu. Very rough running at certain throttle settings, diagnosed as dirt-in-carby, and so had to be left at the airfield on Tuesday. I removed the carb and took it to an old man (i.e. even older than me) in a matchbox sized garage at the back of a courtyard of a crumbling apartment block in the 2nd district, the old Jewish quarter. Helmut looks like he has been working at his bench since Morgan discovered the fourth wheel. The sign above the street entrance (two doors down from Susi who offers intimate services) just says Vergaser (Carburettor.) Helmut's walls are lined with Solex, Amal, Weber, SU and bits and pieces of every carburettor ever made. There's a small lathe in the corner. "No problem" said Helmut, after I explained the symptoms. This morning I returned and picked up a nice clean Weber for a very reasonable sum. One day Helmut will hang up his overalls and the Vergaser sign will go. And then where will we go?
