The last couple of times that I have shut off my engine after it has fully warmed up, i have gotten a "WOOF" sound out the exhaust. It occurs about a second after the engine is shut down. What causes this?

Thanks

Ah... must be a hot dog.

Yes, running rich. I have some different size jets due today or tomorrow.

If it just "woofs" it's only a little rich. Real rich would sound more like a gunshot.

Sounds like it may be comming from your Sub Woofer
