Love the patina
bring some petrol and a plant sprayer.......for starting...battery and decent leads
Petrol gets gunky when old - carb- needle, lines and tank would need thorough cleaning through, any rubber hoses probably perished, and black rubber particles in the lines
turn over engine gently before to get some oil arround the parts, then spray holding flapper open on the carb, if there's a spark it should at least start, and rumble back to life...won't test everything but at least you'll know it turns over and functions
