Found the leak, not happy either. After tightening all of my hose clamps, I found the air leak (RED RECTANGLE) to be between the carb body and the fuel pump. Some WD40 started spitting bubbles when I sprayed it, it starts at about 40 PSI, very small leak but a leak nonetheless. I have dismantled the fuel pump twice, double checking the seals and looking for debris. Not sure what the issue is.
I may move on to the second carb to see if it has the same issue, maybe even swap the fuel pumps to see if that helps. Any ideas?
