I had a problem with a dead mouse which somehow met its maker in the vent
work. It took three years before the faint odour of dead mouse completely
disappeared.

Is there also a pronounced "whoomf" sound when the burner ignites?

I believe it's fairly normal in a gas furnace. In an oil furnace,
however, it can indicate delayed ignition, which is usually
accompanied by an oil smell.
