SOURCE: Yard Machines - Won't shift into gear
The problem most likely is the shaft on which the interlock slides back and forth on inside the transmission. The yardmachines have a continous spinning shaft which ends in a bevel gear. The is an interlock plate which is connected to the Forward Reverse shift lever, this plate slides back and forth and either engages the forward gear or the backward gear. This shaft is most likely galled up, preventing everything from sliding the way it needs to. This is not a difficult thing to fix if you are somewhat mechanical. Disassemble the transmission and check if everything slides

The front belt should be a 954-0280A, rear 954-0370. When you go to higher gears, the front belt should be getting tighter as the vari-speed pulley is moving further back. Remove the shift plate, put the transmission in neutral. Start the engine, put speed selector in highest gear and slowly let out on the clutch. You should be able to see what the problem is. It will do everything the same as if were in gear, except move. Make sure you have the correct belts.

Several questions here...
1. Is the oil serviced to the full mark?
The oil level sensor can cause a no spark condition because it grounds the ignition.
2. Is there spark at the spark plug? You can remove the spark plug and test for spark but if the plug is internally grounded it will show spark when removed but if it is installed it can still be defective. (Spark Plugs are cheap replace it)
3. Is the handle safety cable loose even when depressed? A bad safety cable or an improper cable adjustment can also cause a lack of spark.
4. Do you note gas on the spark plug or is it very dry? If the spark plug is dry try adding a splash of gas into the cylinder via the spark plug hole and see if you get a temporary / momentary start. If you do then you have either a fuel supply or carb problem.
Make sure the fuel selector is in the ON position.
5. If you suspect a fuel problem disconnect the tank feed line to the carb and see if there is fuel flow from the tank, No fuel flow no start.... then problem in the gas tank or supply line.
I will post this as a solution but will watch for any responses and continue to assist you if needed.
Thanks for using FixYa.
