I'm going to agree with everyone else. It's most likely a vacuum leak, just because everything is new doesn't mean anything. Do as others have suggested and I bet you will resolve your problem. Good Luck!

In all seriousness...I chased a vacuum leak on one of my Vortec Chevy's I put together for my boat until I discovered that I had a sand hole in the number 8 intake runner. I'm not saying you do and it has never happened to me in 45 years experience...but it happens. I replaced the intake manifold with another one and the problem went away.
Keep an open mind.

Well looks like i found the problem. I ussually dont let ppl help me cause when they do they say they tightened the carb down and didnt lol. Please god i hope this is the issue. Put a new gasket on tightened down correctly pulled it out on the drive way amd started her. Was able to get it to idle down to around 750 800 ish. I think once i get it in the water a little more fine tuning i cam get down under 700, which is where i would like to be. I got the timing down to 8 dbtdc. I think i need to play with the air fuel screws once i get it in the water to get it just right. I still want to get a new carb with an electric choke since i cannot run the divorced choke with my vortec intake. I think that would help with the hard starts. With all the money i spent this season thus far if i can get this quadrajet to last i will upgrade in tje off season, along with new exhaust. Thank u everyone for all ir help this site is great. I really appreciate your time

I also try to do everything myself. I have had similar experiences with people "helpng". Hope the simple fix is all it was.
