Thanks. OK so now I understand what a pulse line is :) it is intact, no leaks and it is wire tied at. Otherwise ends. When I try to start the engine I can see that fuel is moving through it. Or at least it appears that way. I’ve pulled the needles and the look fine. The carb was pulled and about a month or so ago was repaired by my engine builder. We’ve ran three races fine. I check the passage ways in the carb and they appear fine and I didn’t find any junk or anything.
