First Generation Firebird-L Mailing List ......................................................................... Mark Hello from another CJ owner! Ice had a few of them and currently restoring a CJ5 and a YJ rock crawler. You may want to rebuild the carb.
Or try the original motorcraft 2100 carb as the holley carbs tend to not work well on the old jeeps. Some people have good results with Q Jets. I have a q jet on my 304 in the 5 and propane on the YJ with CJ stuff Paul Z 350 coupe and metric ton of jeeps!
