QuestionQUESTION: Hi John
I have a Craftsman rear drive lawn mower 6.75 Hi-Torque Eagle-1. Model number 143.986710. My problem is that when I pull the throttle lever, there is no compression. If I do not pull the throttle lever, it has compression. I checked the oil level and it is fine. Any suggestions.
Thanks

QUESTION: Hi John
I check and could not find the connection that I was talking about. I also checked the model number of the lawn mower and it is 944.368340. What I am trying to explain is that on the handle, there are two levers. One is to make the lawn mower go ahead and the other you have to hold in to make the mower start. This lever is hooked up to a cable that goes down near the primer. That is the lever that I am trying to find on the parts list. Could not.
Thanks
Shawn
ANSWER: Hello Again Shawn:
The Lever you are Asking About is the Engine Stop/Brake Cable. If you Do Not Hold it Tight to the Handle Bar the Engine Stop Switch and Brake are Engaged and the Engine Will Feel Like it has Compression because of the Brake Band Rubbing on the Flywheel. Tie the Engine Brake Cable (the handle you pull to start and run the engine) to the Handle Bar. Now Remove the Spark Plug and Move the Coil Wire to a Place Where it Will Not Shock you When you Turn the Engine. Place your Finger Over the Plug Hole and Turn the Engine. Does Your Finger Get Blown Off the Plug Hole? If No, then the Connecting Rod in the Engine Has Broken and the Piston is Not Moving in the Cylinder. If your Finger is Blown Off the Plug Hole, then Remove the Cylinder Head and Check for a Stuck Valve. Is the Blade Turning when you Turn the Engine? If No, then Check the Flywheel Key. If the Flywheel Key is Sheared, it May be Spinning on the Crankshaft and Not Turning the Piston in the Engine or the Crankshaft.

QUESTION: Hi John
Just wanted to let you know that I took my lawnmower to a shop and after opening it up, the nut that holds the flywheel was off and all the threads were gone except for about 2 or 3 rows in the middle. That is what was causing the problem. I guess that is has not been since yesterday.
Thanks for all your help. Great site.
Later
