G'day, welcome the forum!


Got any photos of it?


If you haven't pulled the engine yet, then run a compression test on it, thats a good indication of piston and cylinder wear.


Is it fuel injected or carb?


You'll also need to go over the brakes and suspension.
I would do a full rebuild on the brakes, sitting for that long it's very possible some corrosion has occurred in the calipers and master cylinder.
