Any chance there’s 220v going to it?

How can you tell its spinning faster?

If its got an induction motor, the only thing I can think of that can change the speed of rotation would be the frequency of the power feeding it.

I suppose a belt could have been slipping before, and now is not slipping (if it is belt driven).

If it was wired for 120v and now running on 240v doubt it ran for long.
Did you but a new blade on?

I think this is the job site version that has a universal motor.

The question is why do you think it is running faster? Is it the free RPM sound?
