Tim came around with the 3C again this morning and we put in a matching set of Dellorto slide cables. Balanced the carbs with vacuum gauges and all is good carby-wise. But after a couple of starts during the balancing process, the battery ran out of grunt. A quick check with the meter revealed that the charging system wasn't working. OK, no problem, we should have that sorted in no time. How hard can it be?
We spent the rest of the day in the sauna-like workshop (about 35C) trying to get it sorted. By 5pm we decided to call it quits. I'm an engineer and he's an electronics technician and the fucking thing defeated both of us. He ended up going home on my Jota. We'll do battle with the 3C another day. :
Might post something in the technical thread to see if you buggers have any bright ideas.
