I’ve already increased the idle feed restrictors up 3 sizes, I’ve increased the main jet 1 size, and I’ve decreased idle air bleeds 5 sizes.
There is no way this thing is lean.
I even took the carburetornoff thenither day tire it all down and cleaned it very well used 3 cans of carb cleaner and blew out every orfice in the carb main body and the metering blocks and put it back together with new gaskets.
I have a strong feeling it’s strictly cylinder 8 that’s the issue.
Another reason I believe this is cause of all the things I’ve read online with people having issues with cylinder 8 in particular.
But the compression test on cylinder 8 checks out.
So I’m kind of stuck not knowing what to do next to pin point what the issue is.
Tonight I’m going to hook my timing light up to number 8’s plug wire and bring it up to 2500 where it gets rough and see if the flash from the timing light is erratic.
