Yes, vibrations from the line. If you fit a cutting disc to the same machine they will ignore it and you ..... So it is not the engine - although, oddly, if I am clearing honey with the blower (Dadant) and I put the machine too near the hive - say five feet away - then they will sting the rubber cap on the sparking plug. 2-stroke vs 4-stroke engines?>
You forget that engines emit fumes - and those can set off bees. Bees apparently can acclimate, know of a colony into an old engine block. Beekeeper removed, hived, but found bees hanging out around other engines, anything oily was attractive.
