You might want to check if the ignition timing changes a lot over the 800-1000 RPM range.
Some model Spits used a distributor advance curve that had a high rate of advance over the 800-1200 RPM range. The idea was to give a somewhat retarded timing condition at idle (for emissions), and to get the correct amount of advance when the engine was turning faster than idle RPMs. The problem with this approach is that retarding the riming reduces the power output, which slows down the engine even more. Thus, the idle speed can be rather sensitive to changes in the load.
