My Craftsman LT1000 with a Briggs and Stratton 180° Opposed Twin Cylinder 19.5HP 42E707 2275 E1 will only crank 1/2 revolution then stop. I can manually turn it past that point then it will crank 1/2 more rev. I thought it was my starter, so I bought a new(used) one. Had the same problem, engine would only turn half way and stop. Even had a local alternator specialist "rebuild" my starter... no difference. It's not my battery, not my cables... as I have jumpered around them.
I did discover something by accident, I tried to start it with only one spark plug installed (left side as viewed from seat), to my surprise, it fired right up! If I replace the right spark plug, it will not start...
Therefore, I have been starting the tractor with only one spark plug installed and reinstalling the second after starting... getting old! But the grass keeps growing.
Where should I begin looking? Is this a valve problem? I have been told it could be an internal compression release on the cam. How do I repair it?
