Hi Blade47,

The device looks good and let us know how it works.

The way I think muffler pressure should work, is that it should supply pressure when running, then back off when idling. The concern I would have is that the device may allow pressure build up during flight, but would not bleed off the pressure at low throttle and cause flooding, and stalling. However, we won't know until its tried.

Let us know the results of your tests.

My engines all worked well after drilling out the intake to the carb and following the setp procedure described earlier.
