: Mike,
:You may have more than one problem which makes getting her to run right fun.
: You say she smells rich, do you mean raw gas? Usually if it's too rich the exhaust will be black and sooty.
: Also you say you have no adjustment, what happens when you crank her out let's say a couple of turns? Should become really rich.
Mike, If all else fails look for a vacum leak. This might be around the throttle shaft on the carburetor, intake manifold or wiper fitting. Just yesterday the wiper line on my phaeton came loose from the fitting in the intake manifold. Each time I would let of the gas to shift it would back fire. It also idled much faster than normal. Let us know what you find.
: Some things that come to mind,
:Check to make sure the knob on the adjustment rod is not turning on the rod itself, there are some out there. Is the adjustment needle in good shape, not grooved?
:Does the carb seem wet with gas? If so could be a float problem, be it adjustment, dirty or worn needle, or a bad float.
:The backfiring may be caused by a number of things but first get your carb in shape.
:Then ignition may require a tune up, points, condenser, plugs, timing.
:The engine may also be carboned up from not running in tip top condition.
: To me you have a few problems to solve, doing everything is not the way to attack them, one at a time is. Hit the most obvious first, the adjustment is a place to start.
: Good luck and keep in touch with the board with your progress.
