Hi Mitch, not a Victa guru...but I'm into the simple stuff (which will sometimes be the answer) check the fuel filter in the tank, is it clear?...and then check fuel flow through the tube to the carby...and then maybe check the hole in the fuel cap...these block up resulting in no fuel flow....lastly, how is the bottom O ring, any signs of leakage?
I'm sure one of the gurus will chime in and most probably give you the answer....
Hoping this may help...
