Take the freewheel off and soak it in some degreaser (petroleum based) for a couple of days then if you have access to a air gun blow it out. You might have built up a "varnish" on the inner workings and it is just sticking the pall springs.
Regrease the FW. If you don't want to take it apart then you can heat up a heavy oil in a pan in the oven until it is runny (To be done only when your wife is out of towne) then immerse the freewheel in the hot oil and shake it around to get out all the air. A metal coat hanger is good for this. When the oil has penetrated all the innards of the FW cool the pan of oil. Remove the FW and spray off the exterior to remove the excess oil or grease viola you have a cleaned and regreased FW.
Or you can take the FW apart remove the parts and clean them, making sure that you don't lose any of the 8 million 1/8 inch bearings in the process. Tweezers, blue grease, a magnifying glass, and a glass of wine will help in the rebuilding process. Good luck.
