I just bought a bush hog M2561K zero turn mower from an auction a few days ago. The mower would not start before the auction and I thought that it was severely flooded but the plugs were firing. There was gas sitting in the carburator when I took off the intake hose but when the plugs were removed they were bone dry. A cup full of gas was dumped into the carb. and it fired right up and ran fine. Next day.... same thing, except harder to start. Any ideas? Engine has 430 hrs and I figure that the valves have never been adjusted. Also the solenoid on the carb. is working, at least I can feel it clicking. Any help will be appreciated.
