Enjoyed Car Show but Jet doesn't sound right

Sarah Young

Such a beautiful day, just did a 35-mile round trip in my Jet. Drove over to the technical college where the Auto Upholstery and Body Classes were hosting their annual car and bike show. There was a Nash Statesman there and mine was the only Hudson. It seemed to run good until the last half mile to home. I noticed when I went to slow down to turn into my neighborhood. I started hearing what sounds like the car is idling super high, or on a newer car, how it's a lot louder when a vacuum hose pops off. I parked it in the driveway and let it cool off for an hour. The car fired right up but is still louder than ever. Pumping the gas pedal didn't change the idle at all, but the sound seemed to decrease as I was letting off the clutch. How do I troubleshoot this?

Hello Sarah, You said the noise changed as you moved the clutch. Could be the throwout bearing squealing maybee. Is there any free movement in the clutch as you push down on it? There should be an inch or so free play at the top of the clutch pedal movement. Otherwise the throwout bearing runs all the time and will dry out and burn up.
I dont know thats your noise but it might be rather than a motor noise,

Sarah, you do need to try and describe the symptoms a little better for us to give you much constructive. Does the engine idle nice and slow, or has it speeded up? Does the sound go away when you hold your foot on the clutch? Is it a whirring, scraping, knocking, or sucking sound, etc.? Have you checked the hose connection to the vacuum wiper? It could be any number of things, but we need specifics!

Sarah, i had a broken motor mount once that did that, Not in a Jet but it could happen in a Jet. You said you "turned" into your neighborhood and it idiled faster, if the motor mount is broke it could make your engine raise up and put the throttle linkage in a bind, and could of also bent your linkage and the would explain why it is still idiling faster. Just a though and something to look for. I hope you find the problem.

It's amazing what you discover after you walk away from something and then come back to it. My throttle linkage totally disconnected itself. Glad that happened so close to home. I see how and where it's supposed to hook up, but is it just a cotter pin that goes through there or what?

I think there is a pin with a cotter key that goes there. Well I was close! at least it was in the linkage, and not something serious.

Sarah, the clevis should be slipped over the linkage arm and a pin inserted. The inserted pin will be just a bit smaller than the diameter of the hole in the clevis and the linkage. This pin will have a hole in one end and a large head on the other end which stops the pin at the insertion side of the clevis. The opposite end of the pin will be drilled to accept a cotter pin. With the pin installed through the clevis and linkage a washer is placed over the cotter pin end and a cotter pin inserted and bent.

This should get your linkage properly reconnected. Make sure you recheck the idle settings when all is reconnected.

If you do not find the pin that fell out... remove the piece of linkage with the clevis attached from the carburetor. Take the linkage piece to a place like LOWES, Tractor Supply etc to fit and purchase a replacement linkage and cotter pins.

Good Luck

Sarah, Barry is right, there should be a pin. It is drilled for a cotter pin. The clevis at the end should straddle the bracket and the pin should Have a small head on one side and push through the clevis then the bracket then through the clevis far enough to allow you to insert the cotter pin. Hope this helps.

Tech tip for you Sarah - if you loose a cotter pin in the throttle linkage again you can use a bobby pin for a temporary fix.

I live right off a boulevard that has a 40 mph speed limit and was probably going at least 40. So, when I let off the gas and went to slow down, the engine never slowed down because the cotter pin must have fallen out along the two mile stretch where I'd had the engine running at the higher rpm. Finding a new one would be much easier than finding the one that fell out.

And Alex, a bobby pin would make the perfect MacGyverism in a case like this if I'd been any further away from home since the only time I wear them is when I've got my hair up in my '40's Victory Rolls, something I almost always do when I drive the Hudson!
