Yes, the DellOrto's don't have a choke,... in the conventional sense, but an enrichment device instead.
I have had a look at the schematic of these DHLA carbs & I like the way they work. No shaft or butterfly to disturb the airflow. The operation of these enrichment devices is quite simple & should be easy enough to hook up, even if you did it to only one carb.

It would run a bit crook untill it warmed up, but it would start & run.

This mob claim that they have DellOrto parts that even the factory doesn't have.
