Chev 261..... rebuilt stock less than 100 hours...... ran fine..... changed the 3/8 line on the PCV as my curved pipe had kinks.
Engine started fine..... came up to 160 degrees.....BUT... when I turned of the ignition switch the engine mumbled and stumbled and kept on running...popped clutch and it stopped.
Restarted...ran fine... moved it for storage inside a sea container.....when I turned off the ignitionthe same dieseling occured except this time engine seemed to run backward and really farted blue smoke out of the carburator air filter.... now I appreciate why they used to call them flame arresters.
Any ideas where I start looking ...?
Confused...Bob C.
