Thanks Marshal,
Good info. The PO changed over to a single Mikuni.
But included with the bike were several boxes with a buncha parts and what looks like the original carbs, cables and manifolds.
The stuff is old, dirty and covered with grime. But I'm sure under there somewhere I can try to ID the carbs.
Assuming they are the originals. Next time I have the tank off (soon, paint) I will check under the HS.
She does pull hard down low and has a great lumpy idle.
Of course being my first Norton and living where there is pretty much no other Commandos to compare her to, I'm feeling my way around in the dark.
This forum is like a shiny bright light illuminating me way.
Thanks guys and keep the info flowing.
I read all the new posts and do a lot of searching in the old stuff.
Its a treasure trove of info.
