725ex Series engine on 3 Brute Mowers won't start.
I saw 3 Mowers at Wal-mart that looked brand new. All had been returmed because they would not run. I took a chance. The engine started on the first pull, but my satisfaction was short lived.
It ran it for a couple of minutes then I stopped it. I started it again and left it running for another couple of minutes, but on the third attempt it will not start at all.
I even pulled the spark plug and had someone else pull the rope while I held the plug against the muffler to verify that I am getting spark.
I know I'm not the first person to have problems with this engine. Please help.
