Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I own a Toro recycler with a 6.5 tecumseh engine.   When I would start it, it would run and then almost shut off and then run again and so on for the first five minutes or so until it would level off. I changed the spark plug as well as air cleaner.  For the past couple of weeks though I could only get it to start momentarily and as soon as it would start it would die.  Tonight after draining the gas out and putting some fresh gas in I was able to get it to run for a few minutes again doing what it would do originally.  I decided to push the prime button as it was running and it would run smoothly. As soon as I stopped priming it would run rough as stated before then die.  I removed the gas line thinking that this might be the problem as I noticed on one end a few hairline cracks and will replace it tomorrow.  Any suggestions other suggestions?  Thanks!!
