The number is 119 770 778. I doubt it's a Powerplus or Powerminus engine. Just your bog standard cup starter plastic carby 160 Victa churned thousands of in the disco era.

I'm really not after any powerplus motor. Very satisfied with what I've amassed so far. Only wanting a Victa VB (what I nickname the VC 125 mk 3 as I recalled the label saying VB for so many years and only got my memory corrected when I saw my first pic of one in 2016 since my 1988 encounters with the fabled mower) and a purple VC Sport -which I can live without.
After that, that's pretty much it.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
