Now that the garage is all tidy and set up I can turn my attention to actually fixing the cars. A first priority was to get the Sov up and running as it's had starting problems. It's always seemingly had quite a current drain, it flattens the battery pretty quickly if not driven regularly. So first thing was to give the battery a charge. The fuel level was low and had been sitting in there for some time so I tipped in a container of fresh unleaded. This didn't sort the problem and the car still refused to start.
The battery was getting on a bit and I suspected it was past it's best, a new one was purchased. I also bought a cut-off switch to disconnect it when the car is not in use, to prevent it draining. After several attempts at starting the '40 eventually fired up and ran well. Hopefully the problem is sorted and there's not an intermittent fault. There's bound to be a number of components that are past there best which could start failing and cause running issues, given the age of the car.
At least the Sov is running now so that I can move it in and out of the garage with easy, instead of pushing it!
