I think it's the beans. 
 
This being my second time home roasting, with a new popper each time has
produced a burnt taste. At least it's not popcorny, and it's less burnt than
the first batch, which was trundling along for over an hour on the Stir
Crazy platform, but slightly bitter and burnt nonetheless. 
 
I started the poppery II session with a handful of beans (maybe 4 oz- enough
for a good sized presspot) and plugged it in. After 3 minutes I got the
first crack. another 7 minutes elapsed before I unplugged it. I did not wait
for the second crack. The beans had a darker color than my first attempt but
lighter than I normally like.  
Another lister suggested that I remove the thermostat as the roasting may
have stalled. Back to the workbench and a couple of screwdrivers and
needlenose!

Weird.  What type of beans were you using?
That also seems a little fast for a first crack.
My only advice is to maybe measure the beans more accurately.  I tend  
to use either 1/3 or 1/2 of a cup and it's easier to diagnose  
problems if it's an amount that's easier for us to visualize :)

When you added the beans, were they agitating quickly? If so, you may not have added enough. The beans should move slowly or not at all until they lose some water-weight. If they don't move at all, you have to stir them to keep from burning. Too few beans will slow or stall the roast, because of too little resistance against the air flow.

Yeah, but he hit first crack in 3 minutes.  Protective thermostat issue?

If you look in the cup of the poppery poppers.  there is usually a line 
in the metal, an indentation or whatever you want to call it, they put 
in there for the popcorn level i guess it was.  I find that filling with 
coffee beans to right about this line level is working well for me at least.
might want to try it.

SLOW DOWN your roast.  Use an extension cord - maybe 50 - 75 foot long.
Roast on an angle so more of the heat blows by...
Try to get to First crack around5-6 minutes, and 2nd crack around 9-10
minutes...
It's in the passion.

I've used the P II myself and decided that 2oz (c) by volume of green be=

was the way to start the roast.With the expansion and weight loss in
roasting, you get 3/8c and 30g (apx).
When it "seems a little fast for a first crack", there are enough beans in
the popper to retard the air flow. The lower air flow gets hotter passing
the heating element. For me, the hotter air flow accelerates the temperatur=

ramp-up. First Crack starts very quickly and some of those early beans star=

Second Crack before First is all finished.
All of my air poppers are able to do that, and the only additional equipmen=
t
needed to slow the roast is an additional popper, to split the roast into
two smaller batches- the P II and a similar Pumper. I just had to make sure
they were on two separate circuits/ circuit breakers.
The HG / BM can easily do a one pound roast in a single batch, and only
needs one 15a electric circuit. Replacement parts are readily available at
the thrift store where you got the original Bread Machine. The $50 - $150
heat gun will keep running; probably not the $10 one.

Not only hit first in 3 mins, but then went another 7 mins and didn't hit
second. Sure sounds like protective thermostat.
