I have rebuilt 2 stroke carbs for the past 2 years in my shop that I do as a side business.
I have yet to get a rotary carburetor to work right , I've rebuilt them, cleaned them and adjusted the metering levers, they would never work. both the Zama's and the Walbro's.
I have sat and read the service manuals on them several times, no help.
If it's a rotary carb , I just buy a new one and be done with it.
I know this dont help your problem , but dont feel bad, your not the only one having problems with them.
