So True.....
I investigated the power rating discrepencies a while back and found power increase for the New 125 for the Automatic and Model 3 Rotomo was achieved via transfer port positioning, shape and angle. Simply....The barrel design was changed. This explains how they achieved the 3.6hp with seemingly no visual changes.
So there is no Mystery when you actually look inside...:)
This ad clearly shows A Rotomo Engine which was prior to the New generation Victa 125 3.6 engine, and if fitted to a Victa would have retained its 2.5hp rating. So the claim of the extra 1hp would be purely due to the addition of the larger jetted Amal Carby,thus allowing Amplion( if thats what this mower is) to make the higher power and Rpm claim....
Race applications of Victa 125 can run consistently and reliably at 8,000 rpm plus due to Port work and The Amal carby.
So while Victa were masters of embellishment as Jack says, I think in this case the claims may well be fairly accurate...
