    You need three things to get a motor to run

    Gas
    Compression
    Spark.

    Check compression on both cylinders, when the changes were made did you put in adjustable pushrods? Regardless one or more of the valves may not be closing fully so you wouldn't get compression.

    See Mikey and Vinnie build their first motor and it wouldnt run on national TV, all because the adustables were not setup correctly and they had no compression, I was yelling at the TV LOL you could tell because it just turned over and over.

    Check for spark,

    Check for fuel.

    Pretty much it, other parts are fine tuning, unless you have a bad component in the mix. Rule out the others and it will point you to the solution.
