Easy to install

This was easy to install and matched up perfectly with the my Sears LT1000. The new carburetor fixed the problem of white smoke coming out of the exhaust and then stalling out the engine. The old carburetor was allowing oil and gasoline to mix resulting in the white. I also drained the oil and replaced the oil filter. My 20yrs old LT1000 runs perfect once again.

The carborator came in record time. Five days before the estimated arrival time. Install was quick, 10 minutes. I had already tuned up the engine, new plug, fresh fuel, new filter... and when I finished the tractor started on the first crank. Well done.
