So I put my new carb on today. Fire the truck up. RPM flies up to 2,500 rpm at fire up. Adjust the throttle and lower the idle and set it at 850. Has snappy acceleration and is slow back down to idle. Check all the vacuum lines and they are fine. SO I am thinking hmmm, if everything is sealed and lines are tight then why would it accelerate rapidly but slowly come down to an idle??? Well, it turns out this is the same issue I had with my first Edelbrock 600 before I got the replacement. And I believe through driving the carb started to learn the motor cause the slow de-acceleration back to idle was getting better. Not sure but it runs fine and pulls a hill without issue. Choked it while running and the engine died like it is supposed to when everything is sealed. I don't know...we'll see what happens down the road!
