engine and drivetrain Engine Shake When Turned Off...Normal?

['ol_rusty]

Up front: nicely running stock '75 with newer engine mounts (<1yr)

When the car is turned off, the egine gives a good 'kick' meaning one good shake or 'rock'. Is this normal?

Engine is in good running shape and is a factory rebuild with ~50,000, and as I mentioned new engine mounts.

One thing is for sure, this is not 'dieseling' sometimes associated with carbon build up, etc.

Timing? Dieseling is also caused by bad timing, not just carbon buildup.

Also does your carby have a cut of solenoid? If so it could be on the way out.

Just curious why it's not run-on/dieseling?

do you have pollution stuff? How about a pic of your engine bay.

I can work at a picture, but don't think it will help. It was equipt with emission equipment, but all has been removed.

As I said this is NOT dieseling/running after the ignition is killed

The cut-off solenoid is functional.

I'll try to be more specific: When the ignition switch is turned off the engine stops like it should. But as it is stopping it gives one GOOD shake.

It's normal. Look at your trans mount first. Then try to rock the engine with your arms and see if it moves around a bit. Mine does it when it idles high and in general, the mounts are a bit tired. Also the M10 is not a perfectly balanced motor, hence no harmonic balancer.

Also I have noticed that a 2006 focus I drive at work likes to rock the motor once the ignition is off.

try turning it off in gear. i had a big shake going on when i turned the ignition off, then when i tried turning it off in gear it doesnt shake as violently.
