You dont mention your location in your profile, so I would guess europe somewhere?
Anyway, a carburetor car sitting for 10 years in a damp climate will be full of issues. Rust in gas tank, clogged filters, carburetor in need of rebuild. etc. As a minimum, I would think the accelerator pumps are buggered. You can take the top cover off and see if they are stuck in the bores as they will tend to do. The leather gasket can bond to the bore, so soak in wd40 and try and get them to move again. Dont just rip them out as they will probably tear and the replacement rubber ones pretty much dont work.
If you just want to get it in a garage then I suggest pushing it in.
If you want to get it running again, then you need to go over the entire fuel system to get it in order.
