I have a model 612 Grasshopper that I bought recently, if you look at some of my posts I give a little history on it and there are some photo's. I mowed several times with it and it mowed great but lately it has started to run rough, surging. So one day I took all the fuel lines off and made sure there was no stoppage and blew out the fuel pump also then put everything back and it ran smooth as silk. Now it is starting to run rough again and today I mowed about 8 passes and it stopped. I could turn it over and it would start but shut off in a few seconds. This time I took the fuel lines off and the fuel pump and blew them out and put a new gas filter on and it ran good but not the same power it did have. When I was finished mowing it was surging again but keep running without shutting off. Do you think it could be the fuel pump? This mower sat for a few years after the owner replaced the motor with a Vanguard 16 hp and was not able to get it running. Later the owner gave it to a mowing service for payment for their service and they found a loose wire on it and it ran. It has very few hours on it but it did sit for a time and don't know what that could have done. It ran so great at first going through high grass without a struggle and now I am having a problem and since I have used it and refueled it several times I know it is not stale gas and the air cleaner looks new, anyone have any ideas that I could check?
Thanks,
Mike
