Still not sure on the electrics, was busy in the weekend.
I did however pull the carbs and give them a clean, but alas they were surprisingly clean already. Original owner probably drained them before storage.
I did notice what appeared to be/smell a small amount of petrol/oil in the radiator. So I'm guessing i'll be whipping the heads off at some point in the near future.
Will try spark test and electrics too though. Coolant level hadn't changed, and I dumped the fresh transmission oil to double check and it wasnt contaminated.
