Question about my Weber 40 DCOE

[Russkcpa]

On my 1973 2002:

I Bought this car from a fellow '02er in Colorado. The car is equipped with a dual side draft Webers (40 DCOE). I am not mechanically inclined when it comes to carburetors so I had my techs adjust the carb (especially given the Colorado to Massachusetts relocation) They also advised me to install a manual choke which would eliminate a lot of rough running during cold starts. (I installed that myself)

The car warms up quickly (maybe I don't even need a manual choke??) and accelerates beautifully in each gear, however when "cruising along" at 35-40

and barely giving the car gas I will hear what sounds like ticking under the hood but is actually the carb either spitting or coughing. It does the same thing when I cold start . It is mostly just an annoyance as it doesn't hesitate or affect performance.

Any suggestions are greatly appreciated

when you are cruising and just have your foot on the gas you are running on the idle jets. Have you pulled your plugs and looked at them? considering you went to a lower altitude, you might need to change your idle jets. You might be a little to lean right now?

Stock fuel pump feeding both those bad boys? Fuel starvation issue?

Just a thought.

It's not fuel starvation- that happens at large throttle openings.

Check the timing first.

+1 on timing. add a few deg advance.
