The heat exchanger probably rusted through.  Very common with air cooled
engines.  I think the heat exchanger takes heat from the exhaust via
radiator style fins connected to the exhaust pipe.  If this part of the
exhaust has a hole in it, exhaust will be sucked into your heating
system and blown into your face.

Take the heat exchanger off of your exhaust system and take a look at
it.

This is why air cooled drivers are always smiling.

Subject: heater question (bad interior smells)

sorry, forgot to put the subject in on that last email...
I had previously posted a problem with my interior smelling like
exhaust. Well I got it partially fixed. At the time I had a small oil
leak and it was collecting on a hot surface and causing bad smells in
the cabin. Well I got the oil leak fixed and that fixed the problem,
partially. Back then it was warm outside and so I hadn't been using the
heater. Now that the snow is falling, I am noticing that as soon as I
turn the heater on, the bad smells start coming in again. I am not
mechaniclaly inclined but I did get a bentley and if it is just an
unconnected hose or something i could probably handle it. any
suggestions? Another thing I noticed is that no matter what i do with
the heater levers, the air coming out of the defrost vents by the
windshield is always cold. That is not how it should be is it? it's an
air cooled 83 westy.Thanks,Gordy
