99% sure.
but it isn't working properly now... and you are getting the signal from the coil... so it's already a non working tach, so if I am wrong and the PB Blaster makes it worse... you'll still need a tach that works.
I would spray the shaft that the needle is mounted on, and any other mechanical connections in there.

Well it does work... but what makes me wonder is there any kind of like adjusting or anything that would need to be done to it? like why would it rev up but not regiser at idle and also these tach's are only up to 5000 so what happens after 5000?
