Why does Cub Cadet smoke?
If your Cub Cadet LT1042 was made in 2005 or 2006 there is a engineering flaw in the engine short block. It is caused by the block cracking. Look at the engine in front looking toward the rear of the tractor. Now to the left of the engine down around where the cylinder head meets the case there could be a hair line crack running the length of the case. If this happened you are loosing vacuum that makes the fuel pump work. If there is a crack take it to any Cub Cadet dealer and they will replace the entire engine at NO cost.
