My clock worked fine until recently and suddenly starting gaining several hours in 24 hrs it is alarm clock only and says model 22651 on botrtom i could replace it with a new one for a few dollars but i have this overwhelming desire to make it work

If your cuckoo runs too fast or slow, the best way to correct this problem is to set your cuckoo to an accurate watch or clock. After 24 hours, record how many minutes your cuckoo is running too fast or slow. Then adjust the bob up or down the pendulum stick to change the pendulms effective length. You'll need to take an educated guess as to the distance. Reset the cuckoo minute hand time to your watch or clock again. Repeat this process every 24 hours, recording the results, and readjusting the bob until you are within 3 minutes of the correct time. Then, switch from recording every day to recording every week. Use the same process described, recording the time difference, adjusting the bob up or down every week, until the cuckoo is accurate within approximately 3 minutes per week. Remember, mechanical cuckoo clocks are not as accurate as quartz or electric clocks! A three minute error per week is not bad. Maybe you can do better. What you are attempting to do is to obtain is the best timekeeping possible from your cuckoo clock. Afterwards, you will still need to sychronize the cuckoo (coo coo) clock minute hand to an accurate clock or watch, each week or as desired.
Typically, you have to hold down a "Time" or "Clock" button, then press either a fast or slow button and hold it until the display reads the correct time. Some models have hour and minute buttons instead of fast or slow, and a few have a slide switch that you move to the clock adjust position (it would also have an alarm set position) before the hour/minute or fast/slow buttons are enabled. Some clocks reset to 12:00 AM if you hold Clock, Fast and Slow all at the same time. You'll just have to experiment a bit to find out what works on yours.
Changing the clock time format
You can choose to have the display show the time in 12-hour (AM/PM) or 24-hour (Military)
Press and hold Alarm Time (Menu) until -SETUP MENU- is displayed.
2. Press Tune > three times until TIME- is displayed.
3. Press Time - or Time + to select 12 HOUR or 24 HOUR.
4. Press Alarm Time (Menu) to exit the setup menu or wait 10 seconds for the setup menu
to end automatically.
When setting-up the time (by pushing the "mode" button), the alarm time set comes up first, followed by the time set.
When setting the proper hour in this mode, simply continue through the military "24 hour" cycle and the second cycle of 24 hours will be in the 12 hour format.
Continue through and finish the mode set-up function and your up and running. --
I had this same problem. I removed the battery and then unplugged it for about a half an hour. When I plugged it back in, I had to reset the date, time, year, time zone and alarm times, but the alarms now work!!
I'm not on this field of expertise but I could try giving you some tips.
These cloks work by dividing the natural oscilations of a quartz cristal in the corresponding way to form "1 second". A quartz cristal like the one in your clock will oscilate at about 14080236 times per second. Your clock uses a specialised chip in order to count these oscilations and know they form "1 second". However, the problem is the following. These clocks doesn't compensate for frequency variation over the mains power line. You should always look firts at it's power ratings and determine if it requires 50Hz or 60Hz. Even if you use an adaptor to raise/lower the tension from 110 to 220 v or viceversa, this woun't correct the problem as the adaptor will leave the frequency unchanged.
Unfortunately in order to make the required adjustments you woun't need a resistor or capacitor, but a whole bunch of them in order to make a frequency divider-convertor that's stable enough to give your clock a fixed time reference. One more thing, not all components have exactly the parameters noted on them. There's another thing called Tolerance. A 1Kilo Ohm resistor with 10% tolerance (most comon tolerance) can have any value with +/- 10% of it's noted parameters, and in this example, could have any value between 900 ohm - 1100 ohm. These clocks will need components with a very strict tolerance in order to have an acurate time reference.
Note that they aren't atomic clocks, they simply use a larger chip that includes most of the clock, time reference, frequency analyser and divider. An atomic clock doesn't use quartz cristals, instead it relies on the natural oscilations of the very precise Cesium izotope atom. The rest of the atomic clock is made up in a similar way as usual clocks (more fixed and small tolerance of course :) ).
I did not find my manual, but this worked for me. Set the clock to be a 24 hour clock by pressing and holding the Memory/Clock Adj button. The display will show 24h or 12h. Use the fast forward button to change from 12h to 24h. Press the Memory/Clock Adj button again and use the fast or reverse forward buttons to change the time to read, for example, 13:00 instead of 1:00 if the time is 1pm. Press the Memory/Clock Adj button again to set the minutes.When you are done setting the time, press and hold the Timer/Sleep button. Either a time or "0:00" will appear in the display with the word "TIMER" flashing above it. Quickly press and hold the Memory/Clock Adj button until the first digit in the time starts flashing. Set the hour that you wish the alarm to sound using the fast or reverse forward buttons, just like you do for setting the time. Press the Memory/Clock Adj button again to set the minutes, and one more time to finish. The word "TIMER" will stop flashing and go solid, and the display will return to the time of day. When the alarm sounds, you can hit Snooze which will give you 5 more minutes, or you can turn the Clock Radio off. Pressing the Timer/Sleep button again will turn off the timer (alarm) and pressing and holding it again after that will turn it back on.
