new '66 Valiant owner in Missouri

You're right, it's a 170. Glad to see another '66 here, they're a real hoot. Best A body out there. Enjoy it, and if you need anything give us a shout. Somebody here knows the answer.

Read your edit. Pull the plugs and put about a teaspoon of Marvel Mystery oil in each cylinder. Pour about a tablespoon full down the carb. Turn the engine over a few times and let it sit for a couple of days. Change the oil, make sure the gas coming from the tank is fresh, and pour a little gas down the carb. Fire it up and see what happens. It will smoke like a freight train for a while but should clear up. If it runs you're in good shape. If it don't we can help.
