Woodie, you are correct. Your overflow tube is separate from cap location, and must have a restrictor valve at the bottom in order for the 4 lb cap to pressurize. Skip Haney sells one for the purpose, that holds pressure at 3 lbs.
Your coolant does appear to be a pretty strong mix. It may be foaming out the overflow and dumping on the crossover exhaust pipe thereby producing the indescribable smell. Your picture shows a normal coolant level, you can't overfill that design radiator having the fill cap on the side.
