I haven't started the car in almost five years. It's been sitting in my garage and this is in NC so it does not get that cold. I pulled the plugs and put a little bit of 5W-20 oil in each of the cylinders and turned over the engine several times. I also pulled the radiator out and cleaned it with my garden hose. Now my question is do I need to drain the gas and put new gas in her? Also will I need to clean the carbs up to get gas to go through them?
