A note on carburation.

Before I shipped the cylinder head off to SRM, I took a couple of photos of the combustion chambers and sparking plugs electrodes, as a litmus of what carburation is like with the current set up.

A little rich perhaps, but judging by how smoothly it was running (despite the as-of-yet unidentified problem), and by how even the dark hazelnut colour is, I'd say I can leave the carburetters alone and just bolt them back on when the cylinder head returns. At least I got that right...
