The unit that I have is one of the "sealed" (cheaper) units. I can not open it up to repair it. It is about 3 years old and it has me worried since it stopped holding pressure after shut down and I had the weird lean issues on the last drive.

Thank you all!!

EDIT:
I just checked and both bowls still show fuel in the sight glasses. It appears not to have any internal carb leaks.

The unit is a Carter M6866.
