You can try spraying some lubricant into the blade holder. Sometimes the "ball" in the shaft gets stuck from dirt. Otherwise you will need to disassemble it by removing the roll pin that holds the collar on the shaft.
The carburetor has a problem. You can take off the carburetor with a 5/16 socket and a 3/8 socket. Take off the air cleaner cover and remove the air filter. Then remove the air cleaner housing. This is three bolts that can be removed with the 5/16 socket. Take care not to damage the gasket that is behind this. Then the fuel line needs to be crimped. You can do this with lockjaw pliers. Then use a set of regular pliers and take the fuel line off. After this the carburetor has two more bolts that holds it on. They can be taken off with the 3/8 socket. The fuel bowl nut can be taken off with a 1/2 in socket.
I would take it off and see if there is anything inside of the fuel bowl after removing it from the engine. If you see a round piece of metal in the fuel bowl then it has dropped a welch plug and the carburetor will need to be replaced.
Unplug the machine then crank open the head up as far as it will go. Underneath, in the middle of the head you'll find two feed rollers and a cutter head with the blades on it. Even dull the blades are very sharp so work carefully. Each blade is held in place by a blade holder and eight allen screws. Remove all eight allen screws and the holder and blade will fall out. If they have excessive sawdust or tree goo on them they may need a bump from the plastic end of a screw driver to knock them loose. Keep track of how they come off so you can put them back on the same way only with the blade turned around. The top of the blade holder will fit into a channel in the blade so they'll all go back in lined up correctly. Turn the cutter head carefully to get at the other blade(s) to change them.
The pin is probably stuck in the blade. This happens from time to time after they get dirty. Take some WD-40 or some other type of penetrating oil and spray a little in the blade holder while working the release lever. It will probably free right up.
I had the same trouble. The blade holder was out of the knife and would not go back in. I fixed it this way: open the screw knob all the way to the least tension. Slide the two parts open but not all the way- there is a tab on the blade holder that gets in the way if you try to drop it in at the fully open position. With the two halves SLIGHTLY open- slide the blade holder in making sure that the tab is seated in it's slot. Depress the thumb tab and bring it to the most forward position and the two halves should be able to be seated together again.
you can replace the impeller, it requires purchasing the part, removing the motor/ sump assy from the d/w( or uninstalling the d/w and flipping on its back) the motor does separate form housing with 1 screw and a twist. new part(s) are installed and reassemble,
