My older 8 day cuckoo clock with a newer Regula movement has a sluggish cuckoo bird! He is sluggish and hesitant on the first cuckoo, then he speeds up for the rest of the cuckoos. Do I just need to adjust the bellow lift arm up a a little higher? I did adjust the two arms because the back one for the higher pitched whistle was hanging up on the arm for the lower note (or second) whistle. Maybe I inadvertently messed things up. Does this problem sound familiar to anyone? Also, it doesn't cuckoo on the half hour. Maybe it's not supposed to? The half hour is the only time the clock seems to have the slightest gong. I know I need to adjust the gong hammer a little more. Odd that it will hit ever so slightly on the half hour, but not at all on the hour.
