I remembered something about the bit of tube that I was using between the carb and the silicone tube. It had this line around it that I had assumed was measured for the bit that goes into the carb. Then I remembered it only went halfway around. I thought that perhaps this uneven outer diameter could have been my problem so I cut a new piece from another old intake and am using that now. Will test it tomorrow. These pictures aren't super clear but you can see the line I'm talking about.Well, I meant to help solve the issue, then find a more permanent solution after.
