Timing
I own a 1982 Ford 150 that is powered by a 300 six. I just got it back from the machine shop. It runs fine but when you turn off the ignition switch, it continues to run for a few minites and then dies with what sounds like a puff back through the carburator. Guessing it is out of time. Looked in the owners manual but found no timing info. I have a Chilton repair manual but it uses a calibration number. Not sure what that is or where to find it. Pulled off the carburator tag and it does not line up with any of the calibration numbers. Can someone inform me how many degrees before top dead center that engine is timed at. Thank you.

I would try checking the timing with a timing light to see where you are at. It almost sounds like to me, that you might be advanced too far out or maybe have it off by a tooth or so. If that's the case I would pull the distributor, reset the engine to top dead center and reset the distributor. If that doesn't help, I would go after the carburetor next. It is possible you may have your carb setting too rich, basically speaking you are getting too much fuel. While your at it check for vacuum leaks, the carbureted 300s are notorious for intake manifold gasket and carb base gasket leaks. I cured the manifold leaks on my 84 F150 300 six by doubling up the gaskets. I would make sure your carb and manifold mounting bolts are tight. Hope this helps, good luck!
