Thanks Susie, Col,
the T3 is a pretty thing, and in lovely nick. You must be very proud of it!
Plugs are new, gapped, and the Rita seems to do its thing. LeMans don’t have filters, just mesh over bell mouths, I guess it’d keep a spadger out, but nothing much smaller. Whilst I was careful, I guess it’s possible I put the needles back on the wrong slot when I rebuilt the carbs, I’ll give it a few more miles then do an ignition cut from a fast run - that way I’ll get a decent idea of the WOT mixture.
Chokes on a Dellortos are an air bleed, and have a reputation for leaking, thus richening the mixture, I replaced them, and they are adjusted to have some slack in the cables.
The other option would be that the floats are way out. I did check them when I put the carbs back together, and I have fitted new needle valves. Now, that’s an interesting point. There were two fibre washers on each needle valve when I stripped them. That would lower the fuel level in the float chambers, by a bit less than a millimetre, and thus weaken the mixture. I put only one washer in, and set them by the book, and assuming I put the needles back where they were, they might well have been incorrect before….
That’ll be a challenge to sort out. Or I suppose I could just bung in a couple more fibre washers…
More soon!
