If you put a bran new carb out of the box on the motor and had the same problem I would not be posting this again but a second used carb with potentially the same problem is not fixing the root problem. We at Honda (retired) have had big fights with the government over E fuels and small motors for years. Fuel injected fuel systems can overcome the problems caused by E fuels but vac pull systems can not. You will ether be replacing your carb with a new one or you can take it apart and mechanically clean it. You can not spray your problem away. Not my clowns not my circus, but I will say get used to seeing the end of your tail cause your going to be chasing it for a long time.
Then find your area on here and stay away from E fuels

Good luck with this and I will put this out there, just do it and prove me wrong I can take it.
