I:mad: have a wizard mower that has been in storage for a year put new oil ,spark plug,belt.new gas. It ran for about 5 min s now it will start and run for a second or two and dies out

Drain gas and put in fresh. Also replace fuel and air filters

Carb jets are gummed up.carb needs to be taken apart and jets cleaned.main jet is inside carb bowl,this is likely causing the problem.there is a jet inside of it,I use a small spring that will fit the inside diameter to clean all jet openings.owner of gibson mower repair and lawn care.45 years experience in small engine and 2 cycle engine repair.
