You guys know this common one? One pacman screw on the inside one on the outside. I can get it started but doesn't stay running unless I throttle it which only lasts for so long I've put a lot of car cleaner through this though maybe it's that diaphragm in there too brittle as I recall causing such issues

What's the model #? If the fuel pump or metering diaphragm are stiff, they need replacement or get new carb. If you are referring to the Hi-Low jets, Low is always closest to the cylinder. Try 1/2 turn CCW.

I've actually got one of these which I might use but problem is they have their own carb but my craftsman has its choke on the air filter cover itself which conflicts with the choke lever on the carb. I could cut down to fit though maybe
