Just returned with our Cadet GT 2100 from the dealer who was supposed to fix it. After a $280. bill, it is doing exactly what it did before we took it in. It has about 40 hours on it from late last summer. When we start it it runs a few seconds and then quits. I did not see a whole in the gas cap. It acts like it is not getting fuel or air. Any ideas. Dealer is closed now. Will take it to our old lawnmower guy in the future. Paid a lot for this and cannot believe we do not have a working mower this spring.
