I'll let you know if i see anyone selling a G2 for you.
As I mentioned when you were there, this one has an original G2 carby, But someone has sawn the govenor post of, right down at the carby body.
It's a fairly rare carby, but they do pop up now and then, I have most of one here somewhere i bought a few years back, so I will get some pictures up for you!
They had an almost complete MKI VC-160 Auto Drive there the other day, Same as mine, with the green cowl.
The cowl was fairly banged, and someone had pulled the lever bar off, and the dogs out of the wheels, but the gearbox and belt were still intact, as was the full engine etc. I'll get a few pictures of it up when i can!
