California, ah.....
The land where they wanted to monitor cattle "out gassing" and outlaw barbecue starter fluid. And they marched en masse dressed in Nike gear to protest Nike child labor outlaws in Indonesia.
Where they outlawed the sale of pennyroyal oil, one of the most effective insect repellents known because a few idiots were drinking it.
Your generator will be legal. Like was mentioned only SALES of intelligent items are banned. CARB insists chemical laced gasoline that reduces mileage 10% is good for the environment so it becomes expensive state law. Buy your gasoline outside California.
