| The Tecumseh OVXL120 on my 1983 MURRAY lawn mowe is getting really hard to start just this year. It's been used sparingly a few hours per year. Once you place a marine bat in parallel with it's bat it starts and runs fine. Bat is checked and ok. Starter solenoid was jumpered out for test and no change, turns over slow with one bat. When running all is fine. Could the starter need rebuilding, ie. bushings etc. Connect bat to starter post and turns over slow, bypassing key, solenoid etc. It runs well once I get it started, but its really hard to start. Will only crank slow with it's own bat. |

| Following Up: 1. The starter on the bench, unmounted from the mower, spins fine with one battery. 2. The battery EC was verified by a carbon load test at the auto parts store. It has the correct charge and sufficient capacity. 385 cca, lawn tractor bat. |

| I would question the test on the battery. If it turns over well by jumpering with another battery, I don't see what else it could possibly be. Put a voltmeter on the battery and then try to turn it over and see what the voltage drops to. |
