Tycos palm sphygmomanometer VALVE not working after degreasing it

My Tycos wasn’t used for many years and initially during deflating the needle was sort of bouncing.  I sprayed a degrease (CRC) in the valve and started working fine.  I thought that sticky black grease needed to be replaced so I sprayed more CRC until the whole was clean.
