Thanks guys i think it is the fuel or something with the fuel filter because when i touched the f/filter when it was running the idle went up. I didnt notice it but that is what my worker said so i will try the filter first, then if it improves i will clean out those tanks. Thanks ADM, Lawnguy, Grassmaster, Eric and DMC. <p>I tried the switch and its not it but i will try all the small things first and then the major stuff. God Bless.
