Yes, very much so. At the low MP end the governor would drop out of regulation, and at the top MP end it would overshoot a bit.

So a messy/intermittent intake blockage could manifest itself as wildly varying RPM.

Metars for 16/12/09 around 1200:

METAR EGNH 161250Z 32009KT 9999 -RA FEW023 SCT038 06/04 Q1011
METAR EGNH 161220Z 32008KT 9999 -RA FEW022 SCT033 06/04 Q1011
METAR EGNH 161150Z 32009KT 9999 -RA FEW022 SCT033 06/04 Q1012

For some reason can't get the skew-t from Wyoming Univ. Some from here for the general area suggest solid IMC from a low level (which the metars don't support) to c. 15000ft with 0C around 3000ft. Meteox.com shows strong scattered returns for the area.

Could it have been snowing?
