Even though you only set it once, the 4-6-8 cylinder switch on the back of the tach (if your tach has one) can be problematic over time. Work it back and forth a few times to clean the contacts.
Tachs often get there ground through the mounting bracket. Make sure it's not loose and clean it can help.
