I have a scag freedom Z model SFZ 48-600FS with a kawasaki FS 600V-CS12-R engine that I bought new back in 2012. It has gotten almost impossible to start hot and now is surging especially at idle. It starts great when cold. It almost sounds like it's going to stall but catches and stays running. It runs great wide open and doesn't bog down. It has 67 hours on the unit. There is a youtube video out of my exact same symptom where a welch plug was missing but mine are all there. The air filter is clean and I just replaced both coils with oem coils, new fuel filter, new spark plugs gapped correctly, adjusted the valve lash and I finally drained all the fuel and replaced with fresh 89 octane which I have always used due to my Stihl tools needing 89. I took the fuel bowl off and was clean. I haven't touched the carb yet but wondered if anyone has any other ideas before I dig deeper. I can't imagine a safety switch somewhere causing this type of malfunction as that would be either on or off I assume. Any ideas would be helpful.
Thanks, Bill
Another thought is it possible that the fuel emissions canister could cause this?
