WOW! Nice score. Swap out the orifices, and add a regulator hose and you are in business. Or post that
on Craigslist and make an easy $500.
I converted that exact S330 over the summer, orifice swap will not work.
The valves used are variable and you cannot do good flame control.
I bought an entire manifold off weber, ran me about 110 $ CAD and only swapped the side burner orifice.
Sold it off and made about 400$ profit (Monopoly Money)
