I’ve had to rebuild the carburetors on every 2 cycle engine I own - about 8 of them. Also on some 4 cycle yard engines.
Had two Hondas’ O2 sensors go bad, a Dodge 150 and an F150 all because of ethanol.
If Iowa wants to do the nation of ours a service, stop allowing their corn to be made into ethanol for engines.
