Distributor filling itself with oil
Want to make sure you have the proper oil level In the crankcase (5 quarts). Not 7 or 8 quarts.
Messing around with carburetor changes your float may have stuck open filling your crankcase with a Gas/Oil mix that has snuck up on you.
Thinner gas oil mix will wick and seep out faster than a fresh 10w30 oil change.
