Edit: What model?--oops, just missed your post. The smell seems like you are running at rich stop due to some sort of computer failure to control the mixture. Many possibilities . . .The O2 sensor and cat could take on damage if left too long. Manual mixture adjustment could be a temporary fix. I will leave it to others to suggest better solutions. Cheers, Andrew Seidel.
