Question

Why are lawnmowers 4 stroke and chainsaws, hedgetrimmers etc 2 stroke?

Why does my father in law decide to dig a dandelion out of my front lawn with a decent screwdriver?

They are not all 4 stroke and 2 stroke......some are V8's

 

 

 

As for the screwdriver.... at least he did not use your best kitchen knife :angry:

Two strokes are dying, emissions are awful due to inefficient combustion and the fact they burn their lubrication oil. Anything large enough to take a 4 stroke now does - for example lawnmowers. Typically they seem to have small side valve single cylinder engines.
