bad idle

ok I just rebuilt my engine in my 90 yj, got everything hooked up, put back together. When it is parked i the garage it idles great, but when I am diving it out on the street and stop at a red light,or slowing down to turn it gets really rough, it idles about 1000, and it dies unless you keep punching the gass. Im thinking its the piece crap stock carbi have on it. Whats going on?? Would the nutter bypass help out? Should I just get a new carb.? Help Please, i am doing some searches but I just though i would give yall my problem and see what you think. Thanks for the help. [img]images/graemlins/cussing.gif[/img] oh yeah and one more thing. When it dies, if you start it right back up again ad sit there it will idle fine again.

Re: bad idle

It could be clogged idle pickup tubes down in the throat of the carb. Unscrew the tubes, {pull em' out carefully} and also remove the venturi. Spray carb cleaner through the tubes with one of those red strawlike adapters that go onto the carb cleaner nozzle. Do the same with the venturi. Then blast cleaner down the carb throat, but be careful not to dislodge the check-ball. Make sure there are no vac leaks.

Hope this helped.

Re: bad idle

I forgot, lube all the exterior moving parts of the carb with regular engine oil. The choke plate might be getting stuck and not opening all the way.
