Do I need a choke?
Seeing you’re in the upper 60’s F during the day, at best this time of year, it’s a bit chilly at sunrise or at night and a choke would be an advantage.
The air gap is a cold running intake and during my old winters in New York when temps got I to the low 40’s F, a choke would warm up the engine but once I started driving, the choke would come back on. A hot air feed through a OEM or like air cleaner will help a lot here. You can fab up a choke stove off of a header tube.
