Is there a pig sleeping under the hood?

I agree with the belt. You could try starting it without the belt installed (only run it long enough to see if it starts and makes the noise).

It could also be an accessory that is getting sticky.

Good luck.

When I took my smog equipment off, I put a belt on that was too tight. It squealed on start up EVERY time! I put on a little longer belt, and it went away. So I'm gonna vote that it's the belt.
