Fuel system question on CJ7

I finished rebuilding the Carter BBD carb. on my 1980 I6 258. The rebuild took care of most of the idle problems (it doesn't die at stop lights anymore), but created a new problem:
When I hit the gas, there is now a lag until the engine revs. Also, the engine is hard to start, and takes major cranking of the starter.
Can anyone please point me in the right direction, or tell me what I hooked up wrong?
Thank you

Mine does this same thing. It'll be interesting to see what the cause is. Although, my fuel return and vapor blah blah blah are all crossed and clogged I think. That may have something to do with it.

Re: Fuel system question on CJ7

I noticed something else I should add - when the engine is off, and I pump the gas pedal, I can see the gas soaking through the main gasket in the middle of the Carb.
Anyone know what the cause might be?
Thanks for any info!

Me again. One thing you could try is adjusting the fuel mixture. You may have too much fuel, so it's flooding until you hit the petal, which brings in more air to compensate.

Re: Fuel system question on CJ7

I few things you could try to help this problem.. Flush your fuel system. Take a air hose to a compressor and blow it through the fuel line (Disconnected from the Fuel Pump and place in the fuel outgoing from the tank.. This should clear alot of crap up, next replace your fuel pump- takes like 5 seconds to replace, Next replace your fuel pump and the lines going to the Carb. This should cleanup your fuel delivery.... this could narrow down the problem
