gypsy Posted July 30, 2022 Share Posted July 30, 2022 I have a 1976 Chinook with a 20R engine. It has decided to not idle. Usually. Once in a while it will just fine, but mostly not. Especially when I have been at speed and then stop. Like in city traffic. I have done the carb kit. Checked wires, plugs, ignition coil. Everything I can think of, but nothing seems to work. Anyone have any ideas? Quote Link to comment Share on other sites More sharing options...
extech Posted July 30, 2022 Share Posted July 30, 2022 quick fix/ show problem. air filter lid off. rev engine to about 2000rpm. slam choke plate closed till engine almost dies. now see if it idles. if so there was junk in the idle circuit. if not could be a vacuum leak Quote Link to comment Share on other sites More sharing options...
gypsy Posted August 11, 2022 Author Share Posted August 11, 2022 Sorry it took so long...been out of town. I tried that, but without any luck. Have already tried replacing most, if not all, vacuum hoses. Will have to try something else. Quote Link to comment Share on other sites More sharing options...
