I think the lawn beetle is 120cc, there was one at the tip next to the wesco. I would have grabbed it for pure curiosity value, but the deck was all grotty, white sun discolored and awful.
And I think the wesco is about the same - although it probably would have felt like 50cc with the amount of valve clearance this one had.
From memory, gardenline went 99cc, then 118cc, then 139cc, after that it has been 141cc 18 inch and 161cc 18 inch. It has always baffled me how they can make these, ship them half way across the world and still sell for roughly $138.
