Will it run off of choke and mow at all, or only run on choke?
I would attempt to clean the carb out. Sounds like you may have an ethanol deposit blocking the carb jet. Check to make sure your fuel pump is pumping properly, and also check the fuel filter if your engine is equipped with them. Most likely it is a carb issue due to ethanol
remove carb and use carb cleaner or brake cleaner to clean internal jets. Use air if you have access to compressor
