Hi djr1718, Ok, so it does run, then stops. That at least means you have some sort of a spark. Could you please physically check and answer the following:
1.Have you put in fresh fuel?
2.Is the carby clean and getting fuel, and good fuel flow?
3.Is the plug new or the old one serviceable?
4.Is the muffler clear? (you would be surprised what can crawl in and make a nest!!)
