So I just had all the vacuum lines redone and confirmed that there all in the correct place.  Now the truck wont idle at all.  It seems like the gas pedal response is very bad.  Would that be a fuel delivery issue now?  It did sit for awhile before I got it running.  Also the vacuum lines were all messed up or missing.  So now the vacuum lines are done and I will look into other issues.

Did you do anything else other than just replace the vacuum lines? Remove and reinstall the distributor perhaps? Anything?

Nothing was done and it was easier to start before the vacuum lines were corrected.  It is getting good spark.  I have not cleaned the carburetor soI will bet the problem will be somewhere in there.  That is the next job to tackle.  Is it a good idea to replace the carb to something better once I have it off?

Never time to sell. A Datsun will get you through times of no money better than money will get you through times of no Datsun. Store it if you have to. The few bucks you get for it won't buy another.
