But I like "dinking around" with my car! A little grease here... A little oil there... Using my feeler gauges and timing light and dwell meter... And Unisyn... It's a bonding experience... Tune up bits once per year whether it needs it or not. (Usually doesn't...) I also crank start it every once in a while just to remind myself how to do it!

Thats why I dont get that argument, especially after you acknowledge the electronic ignition have many benefits. In 40 years or driving MGs I have had several points fail and one electronic ignition with many many more miles drive with electronic ignitions. The real difference is all the fiddling the points require on a routine basis. I would prefer to be driving then setting the points again.

The original distributor had a cam that would only open the points on a couple of the lobes, the shaft was wobbly in the housing, the mechanical advance was rusty and would not operate smoothly, finally the vacuum advance diaphragm was leaking. Your issues might be just a distributor that needs to be rebuilt. Send it to Jeff Schlemmer and let him Schlemmerize it for you. He's done two for me with excellent results.

>>>>> You can argue the merits of points vs electronic ignition all you want. Fact is, what Wombat said is correct. The way most of us use our cars, it is not normal to require timing adjustment every 4 months. The rule I remember from when all cars had points and carburetors, was to do a full tune up every 10K miles, and a "minor" tune up every 5K miles. The full tune up was plugs, points, condenser, adjust timing, dwell and carb mixture. Maybe replace the rotor and cap. The minor tune up was to basically do the same stuff, but without replacing any parts. You would just clean and readjust what was there, unless something looked really terrible. This was not an MG thing, these were just the rules I learned for typical American cars of the day. In my experience, timing did not change a lot. As Wombat said, wear at the points may require adjustment over time. Timing on my Magnette stays pretty stable. This is with 1500 engine and original points setup. If the distributor is tightened so that you can't turn the body with your hand, then that's not the problem. Overtightening just causes more problems. I would take a look at the points. If they are secure, I would look at their condition. Poor quality parts might wear faster. Also, a bad condenser can cause the points to wear faster.
