The Lt133 was backfiring and difficult to start. Found gas mixed with the oil. Cleaned all that out, New oil, new filter. Replaced the carburator and fuel filter. Now the tractor surges at high speed and the cutters NOT engaged. Seems to run fine at a medium speed. It also runs fine with blades engaged at high speed. High speed in any gear and no blades it will surge.
Any thoughts or ideas would be appreciated.
TIA.
