Took the car to the garage in Rhu today. It'll survive much better in a totally enclosed garage than the tarpaulin cover that was over it. Managed to get a drive around the block in the car (no seats, harnesses, plates, tax, MOT or insurance!!) and everything seemed good. Engine has a tendency to spit back a bit but it's overall not bad. Probably the fuelling needs a good look at (along with new plugs). Was a nice little incentive to get the car finished upon my return...
