Ok, throwing up the bat signal here as we've reached my small and fractional knowledge limit...
Saw starts on ether or 2 stroke squirted into intake. Runs for maybe a 1s and dies. No matter if full throttle or idle.
I rebuilt the carb, new screen, new metering valve, arm and spring. Pretty clean in there. New fresh fuel.
Arm set .065. The gauge, while I havent checked, seems to more like .075, as its pushing metering arm a tiny bit.
Pressure tests 7pds fine.
I did not change the carb settings (H/L at all). Assuming they must be pretty close.
It sounds to my un/inexperienced knowledge, it isnt getting fuel.
Suggestions?
