carburetters dirty,gumed up,and/or the fuel pumps the same. I'm sure you ran it last year,shut it down at end of season and that was it. Obviously it's not getting fuel through the carb. I'm sure it's gummed and should be cleaned, but a quick cheat you may try is, give the carb a good smack on the side with a small hammer. if the float is stuck this usually jars them loose. don't beat on it and break something. if it doesn't work on the first try. Don't keep pounding. You have to find why the fuel is not getting from the tank throught the carb. A 1992? has it been sitting along time?
