Electronic ignition lovers:
FWIW and MO
Advantages?
<<<snip>>>
1. Maintenance which you've already alluded to.
<<<snip>>>
Not really. You still need to pull the distributor about every few
years to clean and lube the centrifugal advance.
<<<snip>>>
2. Top end performance. No point slap means a more consistant spark.
<<<snip>>>
Only if the engine spends MOST of its time running over 5,000 RPM. At
that point the rise and discharge time of the coil will probably cause
more problems than point bounce.
<<<snip>>>
3. No worries about tired bushings, (since it's no longer fired by
the
action of the Dist. Cam) and hence timing is more accurate.
<<<snip>>>
The ONLY real advantage. However if the bushings are now bad, they
will have to be replaced before putting in the electronic gizmo.
Unless you're driving the MG more than 10,000 miles a year, most
aren't, you're not gaining much considering the cost.
<<<snip>>>
4) Better starting
<<<snip>>>
Barely and depends on the system. If the electronic ignition just
replaces the points, it may provide a cleaner break of the primary
circuit, resulting in a slightly higher voltage. If you are still
using the original coil with the system the spark will limited by the
coil's output and limitations.
