My agway snow blower does not start. Somebody told me the carboretur might be gummed up and to clean up the carboretur. Need help locating the carboretur

Hi,
You have not told an engine brand, but the fuel line leaves the gas tank and goes right to it.
Peace,
Clarke

There could be several reasons for it not starting but before you attempt a DIY can you tell us your experience with engine repair?
