Hello all. New to the forum here. I do quite a bit of small engine repair, but I’m struggling with this Craftsman. Wasn’t running- did the carb cleaner check and did the run and die. Cleaned the carb and still no go. Put a new carb on, and will only run with carb cleaner sprayed but will then run until I let go of the bail handle. I had already flushed the tank and line and added fresh non-ethanol gas, new plug, oil, etc.
I even swapped other new carbs i have in stock and same results. Runs as long as I want it to only after the carb spray. Also seems to have an occasional misfire but not major. I replaced the primer bulb and ring and cleaned the galleys out. The linkage and springs look in excellent condition- the springs aren't worn. Any ideas? TIA for the advice.
