I hate making these post.
That is the beauty of a Diesel engine, runs good from 500:1 - 10:1 AFR
Choke on a diesel is useless. Advance injection timing for cold starts.MKI VW diesels had a lever to advance pump for cold starts.
Best way to adjust effective displacement is with forced induction, turbo would be easiest IMO. Just have to keep cylinder pressures acceptable at takeoff power to maintain durability.
