1963 Rambler 660 Engine noise after shutting off

   You could have an automatic choke issue. If the spring isn't connected right it could pull the choke on as it warms up instead of off.

	I filled up last night with Ultra Premium gas, and it was like driving a different car! I drove this morning for about 50 minutes highway and free way and it shut off totally fine, without any residual noise. Thank you all so much for helping me figure out what the issue was I really appreciate your help!

	If the running on problem went away with no other change than to add super premium gas then you haven't solved the problem, you've only masked the symptoms. If the problem is caused by a combination of deposits in the combustion chamber, along with too high a idle, rich mixture, or whatever, they'll come back later. Because with a 8.7 compression ratio, your engine in no way should need premium fuel, the problem is elsewhere.

	Thanks so much Tyrodtom! So do you think I should be looking into adjusting the idle?

	I like to quantify everything. If it's hot, how hot ? You've said the engine seems to idle high, sometimes . If I tell you to lower the idle, without knowing how high it is, may end up with it being too low at the other times, and stall the car at the wrong time. Your mechanic advised you just to shut it off in gear. So evidently he didn't think it was high enough to bother with, didn't have the time, or whatever. Even though it's only about a 5 minute procedure. Turning off the ignition while the automatic is still in gear, with you foot on the brake, can hurt nothing as far as I can think of. And is certainly less expensive than spending 10 cents or more for every gallon of gas you buy. Myself i'd find out why it's running on, but you've really haven't given me enough information to give you good advice.

	That highway drive might have blown out enough carbon to give it a temporary reprieve from dieseling.

	I am not a big fan of remedies in a can, but in this case I think a can of Sea Foam added to the gas or poured into the carburetor with the engine running couldn't hurt . Get a can and use it in accordance with the directions on the can. Joe

	Hi Tyrodtom, my mechanic had adjusted the idle because he thought it was set too high, but unfortunately he set it too low, because after leaving the shop it wouldn’t start when I went to leave that evening. Luckily he came and re adjusted it to be higher, and haven’t had a problem since (knock on wood!) I've noticed that when the car sits the idle seems to get higher as it sits. I start the car and let it warm up for a few minutes before leaving for my 50 minute drive. The idle is very low when I turn the key, and when I come back to leave it's idling much higher, when I give some gas it comes down. Joe thank you so much, I'll check out that Sea foam! I recorded another video this morning of my engine shutting off. This is after 50 minutes of highway and free way driving. average speed of 40 mph and about 65-70 on the free way. I put the car in park before turning it off. The only thing I've done so far was change the fuel type. Thanks so much again everyone for your help! https://www.youtube.com/watch?v=YzJUlrV8-80&feature=youtu.be

	That idle change is the auto choke working. You set the choke by pressing the gas pedal to the floor then letting up BEFORE you try to start the engine. Then start and it should be set at a high idle. If it's a bit chilly (or cold) outside the idle may be a bit low at first, as you have observed. As the engine warms the idle will climb as the engine is just running better. When you tap the gas the choke will turn off (or at least idle down, depending on how cold outside and how warm engine is) and idle will drop. So sounds like the auto choke is working as it should.

	none of this is magical. if you dont have one, get a copy of the FACTORY technical service manual, not a Haynes etc manual, those are junk. the only real way to do this work is to get methodical and go step by step through basic tune up and not look for instant fixes that you dont know why theyh work because it usually means they do nothing but distract you.
