Still working on Craftsman wheeled string trimmer...engine Tecumseh LEV120-361075C. It has been sitting for many years with gasoline in the tank. I emptied gas tank and there was a significant amount of water in it, and the carb bowl. Cleaned the carburetor as best I could. Removed idle jet and removed plastic nozzle, and cleaned all passages. Did not have any welch plugs, so did not remove any. When I start the engine, I have to prime it about 5 times. It runs rough for about a half a minute, then smooths out. However, it takes a few minutes for it to come up to full speed even with contol lever in wide open position. I have the high speed governed rpms set to around 3500. What would cause it to take a few minutes to reach full speed?
