I am no guru.
What has the better life expectancy, a plastic gear, or electric mix pump? I understand where you are coming from 100%.
To the question:
Ferman was just telling me about potential damaging effects of running too much oil. I do know that outboards to run hot with all the extra oil. It also dilutes the effective octane of the fuel your mixing the oil with. Taken to the extreme the motor could pre-detonate if the octane gets too low and wipe a piston. My theory has always been, why would the manufacturers recommend 25:1 on break-in if it was harmful to the equipment? Or was that the old way? I always pre-mixed slightly over-oiling on a 40:1. In an older carbed motor the most important thing is clean fuel and regular use. No amount of oil will do it any good if the main jet on one of those six carbs catches a bit of debris, or you stick a needle, game over..
