I have an 86' cj 7 with weber redline 32/36. Owned jeep for 4 years never any troubles running until now. Recently jeep has been running rough stalling out not idling etc. in the past I'd adjust best lean idle settings with warm engine bringing mixture screw and idle screw back to baseline settings, a little tweaking and all is well. However this time it is not the case. Cleaned out carb., changed fuel filter and no change. With the mixture screw two turns out and the idle screw one turn in after contact with the linkage, ( as the manual reads for baseline settings) the jeep will not run without assistance. The only way it will idle is with the idle screw almost all the way in. The mixture screw will stall the jeep out if turned in but, seems to do nothing turning it out. I also hear a popcorn type noise from the fuel dumping into the barrel of the carb at its best high idle it has now. Any help would be appreciated. Thanks.
