After taking the stem out and doing what I have to do, when I go to reinsert the stem into the movement, I quite often have a problem. It is sometimes hard to reinsert or it does not move from position to position as it is pulled out. Occasionally, I have had to give up on the movement because I cannot get the stem back in properly.
What am I doing wrong? My procedure is that I locate it in the hole where it has been removed until I feel resistance, then I depress the button or lever and push further in. Sometimes I cannot even get it past the first feeling of resistance.
