My snowblower... It has a 10HP Tecumseh engine model: HMSK100. Most small engines are configured in the same way, so this tutorial may apply to other equipment with small engines like this one. |
 |
This is the top of the engine. Notice the blades of grass that should not be there? |
 |
This engine is equipped with an electric starter. The starter does not need to be removed to remove the pull-starter assembly. I removed the starter because a) I don't use it AND b) A screw is missing, so it doesn't exactly work. |
 |
The location of the starter after the starter is removed. |
 |
Step 1: Remove the two (2) screws on the top of the engine AND the two (2) screws near the bottom on the pull-starter assembly (the gold screw on the picture above). If your engine is equipped with the electric starter, remove the block used to plug in the 110v line. |
 |
Step 1b: This is one of the gold screws towards the bottom that needs to be removed. The other wires do not need to be removed. |
 |
Step 2: Remove the shield that surronds the carbuerator. There are about 4 screws that hold the shield on. |

Step 3: Remove the thottle linkage that connects to the governor, which is internally connected to the engine. You do not need to remove the throttle linkage from the pull-starter assembly. Simply remove the screw, attached to the governor, with a flat-head screwdriver and remove the rods (Be sure to note which holes the rods were setting in). |

The four-star resort that the mouse built inside my snowblower. Luckily for him, I don't think he was in there when I fired up the engine. |
 |
No more mice! The nest can be cleaned out using compressed air. I did not have a compressor available, so I used pliers and a screwdriver (no mice found). |
 |
Step 4: Push the pull-starter assembly back onto the engine and re-attach the throttle linkage.
Be sure that you note the way how your throttle linkage connects. Take a picture of it if you have to. I didn't take a good picture of it and it took me some time to get it back together. |
 |
Here is another picture of the throttle linkage.It may not look the same as yours, so take a picture of yours BEFORE you remove it. |
| |
Step 5: Adjust the governor :
a)Before the screw is tightened on the governor, rotate the governor arm so the throttle is in the desired position.
b)While holding the throttle in that position, turn the governor shaft in the same direction which you rotated the arm.
c)Tighten the governor arm to the governor shaft

Step 6: Fire it up!
