Running Generator on Natural Gas

[Smokin]

Been fitting my Gasoline generators for Natural Gas and they are working great. I'm using the Chinesium Despenser and Carb from Aliexpress. $30.
Fitted a Champion 1200 watt and a Homelite 4300 watt. Both run great. No stinky smell. Motors run very smooth.

Why would it leak when the engine is off?

Low quality ng valves may not seat reliably.

That regulator is suppose to be a demand only, opens on vacuum but does it have any kind of approvals? Since its Chinese who knows?
