Wisconsin Pinball

I’m having the Yarkov kickback, the gate next to it and all of the upper Tom cat standup targets working intermittently, anyone ever have this issue before? The 2 flashers above the upper Tom cat stand upswing look like they are working either but everything else seems to be working as it should. Any help would be appreciated, feel free to text, thanks

Saw the board has been touched up before and not very well.Touched up the board best I could and everything is working mechanically still don’t have flasher 7 working apparently but will dig into that at a later time, seems like those flashers have been problems for other people also
