IMO most exhaust cart smell comes from over riched fuel mixture caused by lack of servicing. Nice about fuel injected cart engines most fuel related problems are gone. But in time fuel injected require routine maintenance like ejector cleaning and cold start mode operating properly.

I never thought that they smelled bad. But it occurred to me that their scent was like an engine where you had to mix oil with the gas.
