I traded my laptop for an '85 Camaro last week.
Diddnt run, got it running yesterday. It has hutchison traction bars in the back, and a 305 5.0 w/edelbrock 4bl
It bogs down on acceleration, but seems to gain speed when i pump the accellerator pedel quickly, like a bicycle. If I hold it down, it waddles and doesnt accelerate. What could be the problem? I think that It may be a combination of fuel filter and bad fire. Any comments on this, or anything else regarding an 85 Camaro would be helpful. (or if anyone has any Camaro wheels )

Butchee, i checked the accellerator pump like you suggested, 4 steady streams of fuel into the carb. Any other suggestions? Would appreciate them!

Check for vacuum leaks-you'd probably hear them. Is the manifold a dual plane type or open plenium? How big is the carb? Is it a vacuum secondary carb? So many things that it's hard to pinpoint. Does the thing ever pickup, or always on its face? Is the spare tire full?-someone told me that this mattered!
Hey guys-how about some more input?

it has a 4 barrel carb, i think it is an edelbrock. I can hear a vacuum leak, but I cant find it. Also, when the key is turned on, there is this, tick tick tick tick noise from what seems to be the carb for about a minute or two. Then engine seems to sputter when given gas, then, when you baby it up to higher end RPM's, the engine picks up and screams (it shreds tires in second, i found out a while ago ). I dont think the smog control is hooked up either. I see capped vacuum lines, and there is no belt to the smog pump. I'm not familiar with this LG4 style 305, either.

You may be correct about the accelerator pump. At low acceleration it waddles. When the pedals is floored, and the 4 barrel opens up, then the car takes off like a streak of slime through a goose.

But it seemed like a steady stream of fuel from the front jets. ?

Sometimes the pumps are adjustable to put out a bigger squirt. Try that. Also, if the carb is too big, you'll have no low end. 305 cube would need at the MAX a 650 cfm carb to work. A 550-600 might be better for the street.I had a custom 930 cfm vacuum secondary carb on a small block with tunnel ram that worked real good, but the motor was desgined as a package. I assume the carb has vacuum secondarys. If it's a mechanical carb, meaning that all 4 holes open at once when you stomp it, this will cause the bog on a automatic car. This will also happen if the secondarys open too soon with a vacuum secondary carb. Theres a bunch things to check that are pretty hard to diagnose like we are doing.

Yes, I examined it closely. It is a Rochester Quadrajet, and I ran the numbers, It appears to be stock, chevrolet, mfg 1983. I notice that when the engine is running, and i move the accelerator pump by hand, it jets out, then seems to run down the chamber wall. This coincides with the fact that when I drive it, when i Push the pedal, it seems to accelerate, like the jet, then bog, like the running down the chamber wall. Any ideas?

I only had a QJ apart once. I just dug out a Peterson's Basic carb and fuel systems book I had~circa 1971--I am OLD!!! Tells you about basics up to rebuild. Go to the library and check one out. It has blow-up of the carb and might help you to see if the linkage is hooked up right and settings. This is as far as I can take you without being there. Wish I could help more.

I am still working with this Carb, I'm not gaining any ground. One thing.. I am unable to extract the fuel filter from the carb, due to the fact that the line is siezed to the ghetto chevy redneck fitting they have on there. It shows signs of being pliered to death, so I assume I am not the first to unsucessfully attempt this. Could a dirty fuel filter cause this problem? It seems that it wouldnt jet at all, but mine seems to jet, then trickle. Can't hold it at a steady idle, can only pump it, where it only causes the car to lurch, then decellerate. When I floor the pedal, however, the car takes off like greased lightening . ( I wouldnt know. )

lol, yeah, I would love to! Groceries are more important. I was only wanting to sell the Camaro to pay our way to the TSW weekend. It's not my toy or anything.

a match will help here..when you were asked what kinda carb...size wise...you answered it was made in a year..but ....what size...could be a large one..and its drowning..when you floor it and it dies...does black smoke come out of the exhaust...?? thats too much..if not it could be too little..
stick to the skate board...a can of carb cleaner squirting around the carb base and vacuum hoses etc will alter the idle if its a leak...then throw the hole thing and get a real carb....has to say..holley on it..vacuum secondaries..i agree with butchcee...650.
god do they still make them that small....cute
