Chrysler Repair: Motor problem:59 Imperial, carburetor jets, sticky materials

Question
I bought a 59 Imperial last fall that had set for 20 years.  The tank had little fuel, so we filled it with premium and the car ran like a top.  A few days later it was hard stanting and smoked when running.  I checked the compression and the first 2 cylinders had poor compression.  I took it to the shop and they found that these cylinders had bent intake pushrods.  I had a complete valve job and replaced 3 intake pushrods.  The car again ran well, but later stalled and wouldn't start.  I found that the fuel line had plugged due to the filter.  After replacing the filter I drove it home and parked it.  The very next morning I had the same problem of hard starting and smoking and running rough again.  I have now pulled the gas tank to have it boiled out and recoated.  I have hooked up a temporary gas tank that bypassed the fuel pump (I think the fuel pump is clogged) to move the car so I can work on it.  It does start, but still runs rough and I am hoping that this is because I am gravity feeding the engine with gas.  Could I have done any other damage by having gunk in the gasline that would make the car run rough?  I am waiting to put the tank back in and replace the fuel lines and hook everything up again to see if having the proper fuel pressure and the lack of clean lines was the culpret this time.  Your suggestions would be appreciated on what steps to take after I get it together again.

Answer
I doubt that you did any damage due to the very stale gasoline. But you may want to check the carburetor jets that are easiliy accessible including the one in the float basin and check the choke valve for movement and the linkages associated with the carb. I can imagine there is either dirt or very sticky materials in the carburetor after sitting for that long. So I would try to clean up that unit because it is probably not producing an appropriate mixture. My oldest manual is an '83 which did have carburetors so let me know the model of the carb and I can see if that one might have been used in '59.
