Just want outside to start it for the first time but before I did took off the air breather and it start it up like a champ. Don't know sh!t bout carbs. I do see the coke plate staying open, dats my problem. Do I need a new carb or there's a way to fix it. I do have a Holley 4bbl carb that came off my brothers 69 nova 350 SS. He said he swapped it for a better Edelbrock and the Holley still works. I'll take pix later.

Is there an aftermarket air cleaner on it?

That plastic capmto the left with the pigtail wire in it, thats held on by 3 screws is most likely your issue. there is a heated spring in there that may be done...take it off and gonto Oriellys and they should be able to get you another. Stay with the stock carb if you can...it doesnt get any better.

Check the wire @ choke for 12volts running,if no power check the C-H fuse @ fuse block. Your choke looks like its slamed shut could be the cause of your smoking issue.Hope this helps..
