Hello all. I need help diagnosing my Rochester Quadrajet. I rebuilt it myself, and it was my first carb rebuild. It's on the 350 block that it came from the factory in, so it has the stock mechanical fuel pump hooked to it. Carb worked, but was rough. When cold, I had to pump the pedal 30 times to start, and then it took a few starts to go. Anyway, I'll try to be brief as possible. The carb and block has a divorced choke. I changed it out for an electric one. I don't think that's the issue, but giving that info just in case. Bought a rebuild kit from Carbs Unlimited. BUT, when I got the kit, it didn't contain the needle and seat as advertised, it had a valve type of thing that replaced the needle and seat. I decided to use it. Took the carb apart, cleaned it, replaced gaskets, float, needle and seat, adjustment screws, power piston spring etc. Also, I found that the carb didn't have the fuel filter in it. I always run an inline fuel filter, so I wasn't too concerned. But, since I was trying to do it proper, I put a new fuel filter and gasket, etc in the carb (and still kept the inline filter) Put it all back together and back in the car. Started it - it kept flooding. Pouring out the top type of flooding. Ok, so I got the float level wrong. Took it all apart. Adjusted the float level. Put it all back together. Started right up. Beautiful. Hooked up vacuum gauge. Rock solid steady needle in the green zone. I let it idle for 20 minutes, drove it around the block once. All was cool. Took it on the road later that day and it kept conking out. Had to drive home really slow and pull overt to let it idle on occasion. So, float was too low (I'm assuming). Took it all apart again. This time, I ordered a proper actual needle and seat and swapped out the valve thing... long story - I was suspecting it was defective. With the new needle and seat, I adjusted the float to proper measurement with the needle hanging off the metal and not in the hole. Put it all back together and tried starting it. Flooding again... its even puffing fuel mist out of the choke blade. So that's where I am. Is there anything besides the float to cause the carb to flood? Can something in the power piston assembly cause it?
