So, it was a nice day here in the Northeast today and I went to start up my 1940 Packard 160. It started on the first try as it usually does. As it was warming up, I tapped on the accelerator to slow down the idle but, instead, the speed just increased. I did it again but the engine was now racing and would not slow down. Looks like the throttle is stuck open. How do I fix this so it doesn't happen again? Is there a recommended lubricant that should be applied? If so, how often should this be done and where? I've had many cars with carburetors and this is the first time this has happened. Thanks for any suggestions.

Good Evening...I suggest that you trace the linkage from your gas pedal to the carburetor and see if it has become disconnected...or a return spring has come loose. This does not sound to me like a lube issue. Most likely not a serious issue...just one that needs to be traced and reconnected...Ernie in Arizona

You could have crud in the carb bore that is sticking the throttle plate open. But I would check for bent or sticking ljnkage first.

My clipper did this to me before inhad replaced the floor pans. The pedal mount had rusted away and caused the pedal to move sideways. Which causes the linkage to bind on the firewall.

Thank you for the suggestions. My initial check of the linkages shows no apparent issues but I will look more carefully to see if i missed anything, including the binding issue that was noted. Thanks again.

Check the throttle return spring. It might have become streeeeeeched with use and age and needs replacing. Or use a stronger spring.

My guess - a sticking fast idle cam/linkage on the carburetor.
