I've got several old EMs, and getting the score reels to crisply click through each number is not easy. On some, it seems that every click is very nice, but then the extra energy needed to push those 9-position switches is just too much for the coil to bear, or the spring to return. This is after cleaning.
Is all the magic really in the switch adjustments?
If I just replace the coil with a new one, and the spring is also nice and strong, will they suddenly pull strong and return strong and crisp for every number? I spend way too long trying to get these to behave.
