A relay’s contacts can corrode over the decades especially when not hermetically sealed. This introduces a variable resistance which causes the speed variation. One can affect a temporary fix by carefully cleaning the contacts since the cover is removable; however, this is only a temporary fix and its very easy to bend the thin contact supports making it worse.
