How Far
Problem is Jimmy I'm looking where you live and considering the high humidity of the west coast I'd do the following. Replace the mechanical fuel pump, if that's what you're using, cuss of the old diaphragm, rebuild the carb cuss the gaskets will probably leak when they see gas, put an electric drill on the oil pump and run for 10 minutes then dump the oil and check the oil for rusty color. See where I'm going with this. If everything looks good replace the plug wires, flush the cooling system and fire it up.
Good luck Terry.
