I am in the process of buying a C-code 66 coupe which has a SUPPOSEDLY rebuilt engine that has not been started in 4-5 years. Should I squirt some oil into each cylinder and let it set? How long to let it set and what type of oil would be best? Also the non-orig 4-bbl carb has some mud-dauber mud stuck in the rear 2 "barrels"! I assume it best to scrape this mud out with the carb off and upside down, but do not know how much foreign debris may be left in the carb. Would soaking the carb upside down in gasoline probably flush it out? Advise, please! Thanks!
