|Thanks for the response Greg -
My carbs were purchased new in 1991 from Dave Bean as a kit with the manifold and 2 carbs. They are labeled DHLS45 on top, and appear to have 5 progression holes. I had a Lotus/J-H specialist who did my engine rebuild back then, help with the initial setup and jetting. He used settings close to the lotus spec 5:
7850.9 idle emulsions
This setup ran well for about 10 years when the car began running poorly, missing and I had to change careers so it was parked until my recent rejuvenation work.
I have experimented with the pump stroke which changed the hesitation, but did not eliminate it. Others have pointed to the lean idle jet holder and suggested going to a .7 to richen it up. I live at 2000' ft elevation, which richens up my mixture somewhat anyway. The hard part is that messing with jets is somewhat trial and error, and I live out in the sticks and have limited cash. Dave Bean is up the road about an hour, so I might see if they have parts.
