TTR Renovation - Part 2 - initial troubleshooting

Back at base I decided to go through the whole electrical system testing resistance according to spec, as I had no idea what else might have perished in the time it had been stood. I was pleased to find everything seems to be performing OK and the various kill switches were doing what they should be. The coil resistance did seem a little off, so as it was only £30 or so I put a new one. The sump plug was loose and most of the oil had left the of engine, so I did an oil and filter change for good measure, plus put a new iridium plug in. There were a couple of casing studs missing so I replaced them, plus (backing myself that I'd actually get it running), decided to replace the rear cowling which was flaking away. I also took the headlight apart, drained the water out of it, then cleaned it up inside.

 Satisfied the engine was turning OK and that it had oil and fresh petrol in it, I decided to see if it would start, there appeared to be plenty of compression. Needless to say it wouldn't. Fuel wasn't moving through the new clear pipe I'd fitted by the tap, plus there was none at the carb drain screw, so was safe to say it wasn't getting fuel, I couldn't smell any either.

So I took the carbs off and found the float valve stuck, I gave everything a good clean and put it all back together again. At this stage I should have noted the inlet rubbers were overly flexible, but still.

Given I knew everything else was OK, I decided it was time to try and find a new CDI. They're silly money from Yamaha, but I eventually imagined to source an aftermarket one from Wieltronic in Belgium, via eBay. I fitted it and it still wouldn't start, but at this point we moved house so there was a pause in progress.
