Yep after the engine flooded out I installed a in-line regulator. Another note I should add here, when I rebuilt the carb all I did was disassemble, clean and reassemble. It was filthy inside!!! I'm suprised the thing even ran. I've since installed 2 filters before the pump. When doing the rebuild i idn't check float height or anything assuming it was correct. I'm going to check out the carb further this week and go back to the mechanical pump. Can anybody point me to a good write up on checking float height and whatnot. And excuse this dumb question!! But what are secondaries? I come from the world of CV motorcycle carbs. Car carbs are a whole other beast haha
