[Zmagnette] Timing

I too vote heavily in favor of Schlemmerizing. I'm using Pertronics also. But if your timing is wondering it could be a sign of a loose timing chanson. Check your dizzy for sticking vacuum &/or centrifugal advances first (easier fix!).
Worn/wobbling dizzy spindle bush will cause it to run crappy all the time. Resetting the timing wouldn't help.
FWIW.

>> I got my ZA because the guy I bought it from failed to diagnose a worn out distributor. 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.

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.
