Many modern engines are tuned to run at 15:1, some even 16:1 which is ungodly lean for an IC engine. All in the name of a hotter burn and reduced tailpipe emissions.
Perhaps a 50:1 fuel to oil ratio?
Switching from a 100:1 fuel to oil ratio to a 50:1 ratio certainly would necessitate re-tuning the carburetor as the 50:1 ratio would be heavier than a 100:1 ratio and flow through the fuel ports in the carburetor at a slower rate.
Oops, my bad, lol. You are correct.
