G'day MF,

Yep, that was one reason; another 'selling point'...

Introduced for the 1974 season; https://www.outdoorking-forum.com.au/forum/u...atalogue-victa-1974-range.html#Post62200

Victa didn't get it quite right first time around though; the blade holder pictured in that brochure was recalled, and is fairly rare now.

That 'wave' design had a tendency to bend the crankshaft end, if it copped an object/obstacle strike.
While this problem was well known with Masport 4-strokes [which used a bar blade], it was new to Victa.

Consequently, that holder design was superseded by the 'swirl' design.

Cheers,
Gadge
