Where is the tube "left sticking out" comming from? Is the hot air riser comming from the passenger exhaust manifold (big fat giant sized tube), or is it attached to the oil fill cap on the driver's side valve cover? (or is it something else that's not comming to my mind at the moment *LOL*).

If it's the breather tube from the oil fill cap, replace the oil fill cap with one that is vented (and filtered), but doesn't have the provision for the breather tube.

If it's the heat riser, just pull it off and throw it in a drawer.

I am referring to the big fat tube. So if I understand correctly, it is unesesary to keep on the car at this point?

It's entire job is to get warmer air to the carb from around the exhaust manifold while the engine is cold (the exhaust manifold will heat up more quickly than the rest of the engine so makes a great place to suck warm air from). Warm air atomizes the fuel mixture better.

It's not a necessary thing. The car will heat up and run just fine without it. You'll never even know it's gone, as now the carb is going to breath better anyway through the open filter.
