That didn’t tell you anything. You need a positive stop to verify TDC.
And as I mentioned earlier it appears you are beholden to a certain A/F number. And I would say again unhook or ignore that gauge and make it run correctly and then hook up the O2 sensor again. That gauge can and will lie to you.
Sorry no disrespect but I dont agree. I am not soley looking at the gauge but using it as another reference tool. When the engine hesitates under slight load and the gauge shows a lean condition I feel like that is only helping determine the issue.
