Snapper RP21600 cranks but won't stay running?

Most of the time the carb is the real problem with your situation. I just recently fixed two mowers and found that the problem was the screw that held on the carb bowl. The holes in this screw have to be clean so liquid and air can pass through. Just use a small pin to get the dirt out. Hopefully this is the answer to your problem.

Ed, I wouldn't buy a new mower. You should be able to correct this problem by yourself for under $40.00. First, if you haven't replaced your belts in a long time, get some new ones. Check your pulleys to make sure none have come loose. Then go online and buy a carb overhaul kit. They are around $20.00. I think cleaning the carb and replacing warn parts will solve this problem. But do yourself a favor and buy a repair manual for your specific engine. This will save you a lot of time and stress. You can also get good advice by posting this question on www.askanowner.com
