I am having trouble starting my Hasqvana YTH22V42. I changed the spark plug but I suspect it is not getting gas. I am able to get it running by spraying a quick spray of starting fluid next to the air filter. Then it will run until I turn it off, and even restart. But if I let it cool down or wait until the next day it won't start and I need the starter fluid again. Is there something that can clean the carburetor while it is in use if that is the issue. I am a novice so any info will help. Thanks
