Older. probably, and 2-stroke which necessarily burn some oil and
produce blue smoke. Another reason why I like my 4-stroke Ryobi.

With all the concern about exhaust pollution from petrol and diesel engines,
how long will it be before two-stroke petrol-engined cars, bikes and power
tools (or at least, crankcase-scavenged ones which burn oil) are outlawed,
initially for new sales and later for use?
