It bears reminding for sure, Miller. When I decided to remove F/F choke to make cylinder/improved cylinder my problem was convincing gunsmith of the old Sauer's "no-choke" Bore Diameter. Your reminder is also useful because words have meaning, and nonsense tends to become "normalized" pretty fast. Season's greetings! My never-fail 35-year-old Model 666 JD snowblower is getting a real workout this year.
