The 4 stroke that is the same price is a low spec engine only 3Hp. That was a crazy exhaust on the trimmer Tyler.
I could not find a good example of the Goldline 125cc online so thought I better check some of my old mowers, wasn't expecting to find one .
It's a 125cc 2 stroke and looks like it's from 1980, the engine mounting bolts look like they have no burrs on the hexagonal nuts so there's a good chance the engine hasn't been replaced since new.
The Goldline doesn't seem to have a code number in the Victa Code book,I am only speculating here , If you look at the last Victa ad image it lists,[ A ] Victa Mayfair Mower,I think by about 1980 Victa used the Victa name on some store brand mowers (Mayfair Mowers)
Personally I would like to see 10 Goldline mowers the same for more positive evidence.
I think it's unlikely the two retractions are wrong in listing the Victa 125 cc mower for sale.
