Advantages of electronic ignition.
1. Hotter more consistent spark.
2. More dependable and consistent for years of trouble free operation.
3. Sealed components in an electronic system are less suseptible to moisture. Long periods of inactivity can cause points to oxidize and not make contact so engine may not run.
4. Cheaper in the long run due to less maintenance costs. Don't have to re-time distributor or change and adjust points due to points or cam follower wear.
For perspective, how often do you have ignition problems with your car?
Disadvantages:
1. If electronic ignition is installed, a rare failure usually requires replacement parts. A mechanic can sometimes repair a points system on the water, but you don't always have a good mechanic on board.....
2. You might not be the most frequent customer at the repair shop, and may not get as many invitations to their Xmas party.
