quadrajet 17058475 Air starved the best way to explain
« on: August 19, 2018, 04:41:45 PM »
Ive tried searching for this first and cannot find anything. so when this carb is on my car it isnt running right it just sounds horrible. idling car just sound like crap. when Im out it pops and doesnt want to take off like it should it is sluggish.  I put a holley on to make sure it is a carb issue and car idles and runs just fine. While playing around trying to figure this thing out I noticed if i put my hand in front of the carb and blocked the air from the fan the carburator it idled worse like it was going to die. Then I put the air cleaner (brand new) on and it got worse. Its like it is starving for air but Im not sure what could be causing this issue.  without blocking the air and without the air cleaner it actually sounds pretty good but you can still tell something isnt right.. Im also not touching the carb when I put my hand in front of it im just blocking the air being rushed in by the fan. If it werent for the fan it probably wouldnt run. Does anyone have any ideas of what I should check. Thank you

Not enough details for anyone to help with anything.

What is the carburetor part number?

What are your engine specifications?

What has been done to the carburetor?

More information is better than less.....tks.....Cliff

The carb number is in the subject line. The motor is chevy 350 bored 60 over. It is 11:1 compression. This carb ran fine on a 383 and then I moved it to a motor like the one I described above and it ran fine. I then had another motor built the one I described above and carb is not right. I am not sure what all has been done to the carb I just sent it to someone and had them clean it up and set ot up for racing. Thank you and let me know if you need more info.
