Other things to check/do getting it running again

hi guys just looking for any guidence or a check list of things to do to get a 71 lightweight back up and running. its been sat on my drive for the last 15yrs not started. the last i did to it was new radiator, replacement rear cross member and new brake cylinders and hubs but not touched it since.
i guess im looking for advice on what to check/do to get it running and and in what sort of order,,any tips would be great thanks

I'd try and turn the engine over by hand first just to make sure it hadn't seized. Id probably have a jump pack or car to jump off for first start, check the oil level and have some fresh fuel. I'd also drain the fuel system before trying to start.

I won't expect the seals in the brakes/clutch to be up to much after that long, so a full replacement might be necessary too

1 fire extinguisher, 1 can of easystart. 1 Ignition key. In that order. We need video of your first attempt.

If it fires up, switch it off and check/change oil, water, fuel. Then fire it up again and allow to run up to temperature keeping your eye on everything.

Next step will be seeing if you can get a gear and make it move a few feet and stop it...................... Good luck

Assuming it's petrol, cleaning and setting the spark plugs, points, rotor arm and dizzy contacts would help.

Thanks guys all good stuff keep em coming
