NEED HELP PLEASE!!!!!! engine boggs

[1badk5blaz]

Ok first off I can not seem to figure out what to do. I have a 76 blaz with the 350. It now seems to want to bogg out when im driving(just one day it decided to do that). I just rebuilt the carb which is a edelbrock 600 cfm electric choke. Before I rebuilt it, it was bogging bad and was blowing out black smoke. Now that I rebuilt it it boggs with no smoke. Not sure what to do or what to look for. I am not sure how to fix v8s but Im trying to learn(Im a 4 banger guy). I did put new plugs, wires, and fuel filter on within the last few months. The dizzy is less then 2 yrs old. So if anyone can help I would greatly appreciate it.

Can you be more specific about when it bogs? Engine cold, hot, or at any temp? Light, medium, or heavy throttle, or at any throttle position? Does it bog when you push the gas down a little ways, but smooth out if you really punch the pedal?

It depends. I drove it to work this morning temp was around 180 started to give it gas at 50mph and it started bogging bad. I went to give more and it felt like it was going to die. I would let off the gas give it a sec the put the gas down and it bogged again. It also bogged a 20, 30mph or more. Id say any throttle and any speed. When i drove it home I didnt get on it and it drove fine, I guess I was afraid to gas it and have it die on me.

Could actually be leaning way out. Does this occur only when you accelerate relatively hard? If so I think you may need to check out your accelerator pump circuit, or whatever it is on an edelbrock.

My Holley did this. You could actually make it die if you got on it hard enough. I had to richen up my accelerator pump circuit.
