    Sounds like vapor lock, have you checked your fuel pressure and fuel filter?

    No problems before with old carb, just after install of new, can't believe it's anything related to existing systems?

    Agree, but I have an issue with a bolt on and go new carb, requiring much of anything...going back to old carb that had no issues, just was not as good looking.
