Thanks Rick and Andy. Sounds like you hit on the problem. I cobbled up the
air/orifice part from scrap copper pipe, and drilled a hole for the air, but
not with much thought as to size. I'll try opening up the hole to a larger
size tonight.
BTW, I was quite tickled by the conversion. I just couldn't handle the
thought of $1,000 for a new stove, and the conversion cost just over $100 in
parts, including 3 piezo lighters (which even the $1,000 stove doesn't
have).

Hi Tim,
I can think of two things right away:
One is the air adjustment. If the gas is burning
correctly, you should see a blue flame, no orange, and
little or no soot. Propane does tend to have more
soot than other gases, like natural gas.
If you are getting lots of orange in the flame, and
lots of soot, then it sounds like it isn't getting
enough air. The air gets mixed in with the gas
usually right near the burner, probably right near
each separate burner. Usually there's some sort of
little cover on the pipe leading to the burner that
you can slide to open an air hole more or less. There
are various designs for the air mix, but there has to
be one, so that what comes out of the burner is the
proper mix of gas and air to produce the best flame.
If you can locate these adjustments, then try opening
them up all the way and see if that changes things.
Shut them down until the tips of the flames just begin
to turn orange, and that's probably about the right
place to leave them.
The other is the regulator itself. Most regulators
can be adjusted. If you have one of the round ones
with a bulge on one side and a hex nut cap on the end,
if you remove the cap you should see a plastic thing
inside with a slot in it. You can screw this in and
out against a spring, and that will regulate the gas
pressure.
If you don't get enough pressure, you should have a
very small flame, even at full burner. If you are
getting a whopping big flame, then maybe you do have
too much pressure. I've adjusted these on gas grills
with no problem. You can turn the adjustment thing
with the grill burning to see the results immediately.
Don't turn it very far until you can see exactly what
effect you are having.
Hope that helps.
Dick
