Hi, my name is ***** ***** me review the issue, and I will be more than happy to help resolve it as quickly as possible.

Expert:  JON replied 10 months ago.

If it will start and but dies off with-in seconds, it is the carb. You have a clogged jet that is not letting the carb pull its own fuel. Will need to remove the carb and clean internals. If this is a Briggs engine, and has the bolt on the bottom of the carb bowl with holes in it, this is your main jet for it, and can be repaired just by removing this bolt, cleaning through all the hoes on the bolt. use a bread tie or thin wire to run through the holes to ensure they are clear of debris.
