I'm out trying to tune the Carburetor when I noticed the Choke is stuck open. . . But when I started the car I also noticed a lot of white smoke coming out of the exhaust. Oil doesn't look milky But does have clear liquid looking stuff in it. Oil also does need to be added. I was tuning the Carb because of bogging/Hesitation in acceleration and engine wanting to cut off every so often. Also Engine is not over heating that I am aware of, or at least the Temperature Light doesn't come on. Before I drain the oil to check for 'Milky Oil' I wanted to get a second opinion on a possible blown head gasket.
