You don't need a new tach - the setting requires an adjustment. And to
answer your question about whether it should be repaired - absolutely yes!

Hello -

Our mechanic verified my hunch that our tachometer is reading 100rpm low.
(At all ranges). Should the tach be repaired, or replaced? (Or left
alone?) Also, if I get a new one, is there a way to have the indicated
hours made the same as the existing one?

TIA
