CM871 poor power and fuel econ

[Grounded Pilot]

Thanks, I checked the list and probably need to go about 10-12k. Averaging about 5.8mpg since the retune. I checked the water filter and it is a chemical free one so that’s good! Lol!

I ran a air in fuel test when I got home today and it has a bunch of tiny bubbles in it. I’m assuming that’s a NO NO according to what I’ve read in regards to the test, but it’s the first time I’ve ever ran it. I will post a video. I had it cracked open so that the tube was full and had a good stream coming from the end. But I’m pretty much in the dark as too how fast the flow should be. I bypassed the water separator and didn’t change the test. It has new fuel lines from both tanks to the splitter and to the aux fuel pump.

Fuel filter was replaced 8k miles ago because I got some junk B20 fuel. I’m going to get a new one tomorrow and get it put in then test it again.
