HI,

I recently got Grandmas 1970 Plymouth Duster out of storage where it has sat for maybe the last six or seven years and after the appropriate TLC to get the fluids happy again she is running like a dream (with only 58,000 original miles I'm not surprised) but I've got a strong gas odor coming from the carb.
With my limited knowledge of such things I believe I have traced the source down to what the Chiltons says is the Hot Idle Compensator Valve. It appears the Valve Plate is completely missing and maybe even the valve itself as there is just a cavity there with nothing in it that I can spot. Now, I've done some research online and it seems as though this was a misguided attempt to create a controlled vacuum leak to let the car idle better at temperature. I guess I have two questions.
1) Since the general consensus is you don't need to have this, is there any way to adequately seal the hole and close the vacuum leak?
2) I've been looking for a valve replacement but I cannot for the life of me find anything. Does anybody know where I might be able to find a HIC valve and plate?

Please help.

I did not find the right solution from the internet.
