A couple of people have danced around it without stating it so I will. Carb?ed engines with mechanical ignition (meaning points and distributor, OR a magneto) are very likely to run like crap for a long time before complete failure while the more modern replacements can leave you stranded in a heartbeat. Would I trade? No way!
Meanwhile the rest of us have to put up with the added polution your car is putting out until you get it fixed.
I’ll take electronic ignition any day of the week. Do they fail…sure they do…But how often…1/10,000…or 1/100,000 will have a failure in 300k miles usage…And for POINTS…100% of them will fail in 300k miles more then once. I’ve replaced too many points in -10 degree weather during the winter…NO THAT YOU.
