carby is an LM, easy carby to sort out
As NormK pointed out, the carburettor is an LM, all PowerTorque engines should have been fitted with an LM carburettor.
All of the PowerTorque engines are 160cc, and as has been said, all have the LM carby. The G4 was actually phased out some six years before the PowerTorque engine came on the scene.
oops, thanks guys, must have misread the manual.

The white bit normally had foam in it and fits in the cap. It just prevents fuel sloshing up and straight out of the tank cap breather.
As you have it in the first photo, put the cap down on it and then you should be able to click it in - that being said my Standard 2 one always stays on the tank when I take the cap off.
As Tyler pointed out, the white plastic piece in the fuel tank is part of the fuel cap. Turn the cap upside down, place the plastic rim side down in the centre of the cap, and push gently to click it back in place.
The white plastic item is called a baffle, and as has been said, it's there to prevent fuel sloshing out, while allowing air in as the fuel level drops. It should just clip into the cap.
Thanks guys :), Ill give it a shot clipping it back into place. The foam bit Tyler mentioned, if that's true, do I need it ?
As for the blade spacers (usually yellow or green), technically you can (GA number BLH1416) - main problem is getting a shop to sell them to you. They will just want you to buy a bolt set at minimum or a full blade and bolt set.
Don't bother with the blade spacers, I don't. I use them if I have them....
The blade friction washer part number is CA09347A, however, in the brief searching I've done I can only find them as part of a replacement blade/bolt kit. The part number for this kit will differ based on the width of your mower and the length of blades required. In my opinion, the friction washers are a good component to have installed. They stop the blades rattling, and provide additional friction to prevent them from swinging too far off course.
Awesome, thanks guys

. I'll check them out and grab a few for spares too.
Speedy, don't you notice any issues without the spacers ?
Hi Widget, any 160 Victa gasket will fit...
Head gasket GA GSL722 or Victa EN72516A will fit fine.
Excellent, glad to hear! The other part number I came across, I could only see a bundle with piston+rings+gasket, but if other gaskets fits, I'll go that route

Fuel line spec: 5mm ID, 8mm OD.
Alternately there's plenty of people selling them on ebay, just search Victa fuel line.
Thanks bigted, I'll check it out

Anyone know what plastic material the carbies are made out of ?
Thanks again for all the info
