    Welcome to the Hulk.

    Have you done any of the other fuel line maintainence?

    Replaced fuel hoses?

    Replaced petcock?

    Replaced/rebuilt the fuel pump?

    Removed the autocock?

    Have you verified your carb adjustments?

    Have you checked your piston wash?

    Have you done a leak down test?

    Have you indexed your crank?

    Any of these can cause an issue.
