I had recently rejetted by DCOE 40 webers. I had ignored that old adage that says change one thing at a time. I swapped out both idle (45 F9) and main jets (125).
I had finally resolved the poor idle to main jet transition, but I kept thinking I had lost some umph.
I went back to the original main jets (130- but they look like they have been drilled out) and now she is back to the old hooligan she was on throttle, but with the new and improved slow speed running. I think she is a bit to rich but the power is back.
Swapping main and idle jets is easy and kinda fun, so if you want to see if there is more power to be had, give it a try.
