I fitted an Ingitor breaker and condenser less kit on my 1750 3 years ago. About £ 75. It took less than an hour. Drove the engine hot, loosened the clamp and fettled the distributor to the fasted idle, fastened the clamp an adjusted idle speed and haven't touched it since. After two days I weakened the idle mixture screws one or two clicks each, not touched that since, either. With the points I had to adjust gab and mixture every second month.
The engine never pinks and fuel consumption is about 31 MPG
