My f-s movement wheels turn but the adjustment doesnt go up and down. Could it be frozen or sonething? Should i remove it from the base and try and find the problem?

Just notices on some sessions clocks , turn adjustment to the right to slow it down and and to left to speed up. Some american clock are turn to right to speed up and to the left to slow down.

but do you know why.My clock starts running fast at the start of summer,And then starts to slow down going into winter.
