Just inherited a cream (cream!) SWB series 3 hardtop from my dad. Was apparently owned by Worcester Hospital. It’s a runner but not taxed or insured. Starts immediately (electric pump) but takes ages to warm up and i have to use the choke for ages. Stalls a lot. AND the the back o/s wheel either spins or locks up under braking so am using LR 4WD on soft ground a lot. Use it in forestry work. So...where do I start?!
