I have a Cub Cadet LT1018 riding mower with a Briggs and Stratton 18.5 HP OHV engine (model 31Q777). It's about 3 years old. It seems as if the engine starter is not turning fast enough to crank engine. It seemed to work OK at the beginning of the season, but has gotten a little more sluggish as the season progressed. I've replaced the battery. I've even tried to jump start the engine using my truck, but the mower engine turns slowly but still won't crank. Do I need to replace the starter? Thanks for any advice.
Toro Wheelhorse 38 will start fine when warm. but if it has not been started for 3-4 days it begins to crank but then stops
I replaced battery and still happens
I have heard of " flat spots" in the starter motor
Should I replace starter motor or is there something else I should be looking at
never crank engin more than 5 sec at a time. a great deal of heat is genarated in the motor.try checking the carbon brush.cold temp will also cause the batt to loss charge.also check the carbs to see if there is any water inside.
I am having much the same problem with the exact same engine in my Craftsman tractor mower, Dave. If I hold my mouth just right and not turn the key over quite all the way most of the time it will eventually start, but I'm also trouble shooting the problem trying to get to the bottom of whatever is causing the engine not to crank right. I'll be most interested in whatever answer you get.
1. First check to be sure your battery connections are clean and tight. 2. If you live in a cold climate and are trying to crank the engine when its below 40 degrees F try changing the engine oil to 5w-30 ot 10w-30 oil. 3. Check your valve lash clearance should be .004 to .006" this engine has compression release. 4. This engine has had problems with the carburetor leaking fuel and filling the crankcase up with gasoline, the carburetor can be repaired but special tools are needed. 5. Is there adequete oil in the crankcase? All these items need to be checked prior to replacing the starter.
