If the battery and cables are good, then it's likely either the solenoid or starter motor is failing; doesn't matter which because you generally replace them together as an assembly. But before you shell out $80-$100 for a new starter, be sure you've checked not just the connections at the battery end, but also the other end of the heavy cables going to the battery. The heavy red cable goes from battery to solenoid - make sure the nut is tight that holds the cable onto the solenoid. Be sure to disconnect the battery negative lead before you put a wrench on that solenoid terminal - shorting it to the chassis would cause a disaster. Also check the heavy black cable that goes from battery negative to the chassis - it is common for rust to occur at the chassis connection. If so, just take off the cable lug, clean the chassis and lug surfaces with a wire brush or sandpaper, and retighten the bolt. Good luck!

Can't get exmark mower with Kawasaki motor to start


Have had this problem with the Kawasaki engines and found the starter to be bad. The old starter was turning it over but was not fast enough to start. Have also found weak battery that did the same. The first one I ran into was a FH680 Kawasaki and spent about 2 hours trying to figure it out and it came down to the starter not turning it fast enough. Put a new starter on and started at just the bump of the switch. Let me know if this helps you out

it maybe that the battery is getting old or is not the right rating if the AH Start rate is too low it will not have enough power to turn the starter motor. ensure the battery you use has enough Starting Amps rated. if this is not the issue have the starter motor checked out.


I hope this was useful.

Toro wheel horse 15-44hxl wont start


What motor do you have. Briggs & Stratton motors are notorious for the valves getting out of adjustment. When this happens they frequently develop a tight spot that is very hard for the small batteries and starters to push past. This often results in this sort of condition. Sometimes you can help it by jumping it off another battery to boost the cranking power, however it's best to get the valves into proper adjustment. If you have good connections and have ensure that your starter is getting enough power, make sure you have spark by pulling your plug (the motor should crank well even if valves are out for a spark test, it shouldn't hurt anything doing it). If you have spark and all else is well, check the valves. If they are right, you may need to re-clean the carb if you still can't get it to fire, focus on making sure the idle jet is clean. Also make sure it hasn't fallen out. These jets are tiny and can EASILY fall out of the carb and disappear unnoticed when you remove the fuel bowl to clean it. (speaking from painful, embarrassing experience)

Will not fire when switch is turned to start


Will not crank or will not fire? Most modern lawn mowers only use the battery for lights and turning the starter. If your battery wont turn the starter take it out and have it load tested at the parts store. You may find the battery doesnt have enough amperage to run the starter motor.

Have the battery tested at an auto parts store to ensure there is enough power in it. Sounds like it's strong enough to turn the motor with no compression (spark plug removed) but too weak to turn the motor with compression. Also check for loose or corroded wires.
