1) The points lifting cam bears upon the distributor shaft. Wear can occur at that point, especially if it is not lubed properly.
2) The actuual opening (parting) of the points affects timing. Nothing to do with dwell. Dwell affects spark energy and if point opening duration is too short, then the points gap should be decreased and vice cersa. I would think that on a 4 pot motor operating at around 2000 rpm, dwell is not too much of an issue. However it would be an issue on an eight cylinder motor running at 4000+ rpm.
If play in dist is affecting spark gap, you have touble with it and should address this before failure. If it is only backlash you are referring to, it should not affect timing as it should always be timed by turning the engine in the direction of rotation. If you are that fussy with timing or can't do it that way, use a timing light (but check the advance curve, if it has one.
Yes, fuel mixture could be too rich. Look at the plugs tips and assess by colour/ deposits. Adjust carb as necessary. Could be caused by other issues such as valves. Have you checked clearances. Engines will always slowly 'go off tune'. That's why they all need serviceing at
regular intervals. They are not like the modern engine which needs much less intervention due to technology improvements.

To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
