(quoted from post at 12:48:31 07/26/13) The plugs are new. I reset the points after I ground the screw thickness holding the points in the Dist. It was making contact with the moving part of the points and I think it was shorting them out to begin with. When I pulled the carb apart the main jet, the one that sits front to back at a 45 degree angle was at 2 1/2 turns out so I started at 2 1/2 turns out and the idle screw on the side at 1 1/2 turns out. I'm going to reset the two mixture screws and try again as soon as I get outside. I checked the spark with a timing light I had used for timing my cars in the past and was only getting a spark once in a while so I checked the dist and found the screw holding the points at the adjusting end was being rubbed by the points as they moved back and forth. After I ground the screw down, I had a consistant spark.

Sounds to me like an advance weight problem!!... (not advancing the timing, so will only run @ idle)
You may think...you have NEW spark plugs....but blowing black smoke, tells me you have contaminated/sooty plugs NOW!!! Yer gonna have to pull and clean, each and every plug, before they will fire hot enough, to run that engine.!!!
1954 NAA...134CI engine, should have a TSX428 or a TSX580 carb.!!!
Initial setting should be 1 Turn out on the side pointing idle/air adj. screw, and 1 1/2 turn out for the main fuel adj needle.....start at full idle....let the engine warm up to op. temp....then, adjust the idle air screw, IN to get the highest smooth idle!!!! (1/8th turn at a time....listen for highest RPM)
After you check the engine running at idle....THEN you can set the main adj fuel, for max. fuel needed to run the engine @ full running under load!!!!
Ya want more help????? I can try to give it to you, but DO NOT REPLACE any more parts, until you find out for sure what is causing the problem.!!!!
