Sounds like an experiment is in order - to see
if it cleans plugs, too. However, Ed's point about lead fouling has to be
kept in mind - we are talking about two kinds of fouling - carbon and
lead.
. . . I'd think the "water cleansing thing" might
not be as effective up inside the spark plug ceramic area as on the more exposed
rotor surfaces.
About lead, Ed gave some good tips. His
tips about selective use of EC-2 features to increase temp in the rotor's
combustion chambers is consistent with the standard practice with air cooled
piston aircraft engines - when rpm drop is too much when checking mags during
pre-flight run-up, and it runs rough on 1 mag, we increase the rpm to generate
some heat and lean a bunch while running up on the ground - usually clears
whatever fouling (lead, assumed, or carbon) was causing the misfiring.
Clears up in 30 to 60 seconds of running.
. . . Doing Ed's equivalent in the air sounds like
the same principle and seems to be good advice.
