Thanks to synthetic two stroke courtesy of Aldi special buys, my 1982 Victa Mustang found in a rubbish pile, has a transparent exhaust that won't attract sneers from neighbours and passers by.
The noise will do that all on it's own

The finished lawn will attract accolades or at least an absence of said sneering reactions.
Our neighbour went and got one of those hopeless Ozito plastic lithium mowers. It couldn't cut it's way out of a damp paper bag going by the weed ridden mess of a patio.
I feel guilty not fixing up a four stroke for him in time.
(He prefers a four stroke).
