I would check the condition of the cat converter as it sounds like it is breaking up and blocking the exhaust pipe. The smell is hydrogen sulphide (rotten egg gas) and is the by- product of the cat converter action

that smell is usually a sign of the catalytic converter which is the first wide muffler looking thing under the engine after the first pipe from the engine.

it is happen to old engine because the oil that escape from the engine(engine cover near the exhaust) when it is got hot it sends bad smell but after how many minutes if it already dried up because of heat it will gone (like frying using the used cooking oil in pan there is a different smell).

It sounds like you have a plugged CAT, The Sulpher smell

the rotten egg smell is a catalytic convertor going bad. here are a few symtoms.--- you should notice a drop in power and also a higher running temperature,also at night you may notice a slight glow from this thing if its heating up,it will also loose power ,on any kind of a hill or small incline it may idle rough from time to time also,there are several warning signs of one going bad ,if your in doubt about it,you can have it checked,they can drill a hole in it and check the back pressure on it,this will tell you if its going bad,this is actually the best way to check it out. have a good day !!

1 Inspect OXYGEN Sensor Damaged or Faulty OXYGEN Sensor or Circuit. 2 Inspect Timing Specification Incorrect Ignition Timing. 3 Inspect Catalytic Converter Clogged or Faulty Catalytic Converter. 4 Inspect PCV Valve Plugged or Damaged PCV Valve. 5 Inspect Carburetor Dirty and Improperly Functioning Carburetor. 6 Inspect Hose (PCV)at Clogged or Collapsed PVC Hoses.

Rotten eggs is usually a good sign your catylic converter has gone bad or is severely clogged. It will smell bad at first and then you will loose power over time.

Sounds like you may have a vacuum line off or ruptured going to the EGR valve. The burning smell is probably the catalytic converter. When the engine runs rich you will get a sulfur smell that smells sort of like rotten eggs.
