NEW!: For your convenience, the information on this page now available as a PDF, HERE


After endless searching for the proper connection of the linkage on my Craftsman mower's engine, I found the answer. I put together the following page with the hopes of helping someone else avoid the nitemare that I encountered. Please forgive my rather crude pencil sketches. I hope you find this useful. Please note that my diagrams and instructions are correct to the best of my knowledge; however, I will not be responsible for any damage to an engine or physical injury. Use this information at your own risk. Always follow standard safety precautions.
Thank you,
Neil

CARBURETOR, TOP VIEW
Above is the top view of the carburetor. The wire without the spring has one end connected to the throttle and the other end connected to the top hole of the governor lever. Since this is a top view, you are unable to see the bends in this wire. The belly of the bend will face the carburetor. The long end of wire (past the belly) goes to the governor lever.

Below is a top view drawing of the linkage to the throttle control. The spring connects to the lower hole of the governor lever and lays below the solid wire shown above, in a cross-over fashion.
THROTTLE CONTROL, TOP VIEW
(Cover Removed)
The diagram below shows a side view of the linkage connected to the governor lever. This shows how the linkage to the throttle control passes behind the solid wire from the governor to the throttle of the carburetor.

FIXED THROTTLE VARIATION
CARBURETOR, TOP VIEW
The above diagram shows the same style carburetor with a slightly different linkage configuration. There is no throttle control--only a tab that is bolted to the intake manifold, which holds the throttle open. The solid wire still runs from the throttle of the carburetor to the top hole of the governor, as shown in the previous diagrams. In regards to the other piece(s), the spring will connect to the hole in the tab and the other end will connect to the lower hole of the governor lever, passing below the solid wire.
