Yes I did. For a while it would error out on Lean. But there was zero doubt I was running rich. On a warm day, it worked for a few minutes and displayed in the 13s - which is rich and I felt accurate. Than leaned out. Fixed the carb, redid the curve and threw more initial and low and behold it started working . It went through a bit of a cycle as I was driving. Been reading 14.6 since. To be honest, I am not 100% confident in the reading.
