This sounds like classic vapor lock. Heat from the engine is vaporizing the fuel in the carburetor before it gets into the cylinder. Next time it happens, try icing down the carburetor and fuel lines and see if it starts up.

maybe its worn and stretched...replace it

What you describe as slow may be starter stall. Starter stall occurs when decompression fails which is typically due to the valve lash out of spec. The Kohler Courage is an OHV engine that requires periodic valve lash adjustment.

Try removing the spark plug and then engage the starter. If it still cranks slowly then the problem.is not related to decompression.

Raise and secure front of mower off the ground.
Remove large wheel cover (if in place).
Remove small dust cap.
Remove cotter pin.
Remove castle nut.
Remove flat washer.

The wheel should now be loose and the outer roller bearing can be removed. Next slip the wheel off the spindle. Take care not to loose any parts from backside of the wheel.

Likely the starter solenoid or the brake actuator module.

You'll need to measure the voltage at the starter solenoid coil. You should read battery voltage across the solenoid coil when the ignition switch is in the start position.If you don't read battery voltage, there are multiple causes for this fault.


For engine START, this unit requires the following;

PTO switch OFF
Steering arms OUT (brakes fully applied)
Operator seat occupied.

When steering arms move OUT the brake actuator module applies brakes and allows the power to the starter solenoid coil when the ignition key is rotated to the START position given the 3 conditions above are met.

The brake actuator must rotate and apply the brakes or the unit will not start. Any obstruction of the brake linkage that prevents full brakes or if the actuator is out of adjustment will prevent starting.

You got a bent spindle shaft,or a timing belt issue,or the wrong blades on the unit !

Check that the spindle, tensioner, and idler pulleys are nearly in the same plane (same height above deck). Check that all pulleys run parallel to the deck.

Double check part number on belt is correct for the machine.

Release belt tension, see operators manual, and make sure all spindles and pulleys spin freely. Spindles and pulleys should make little to no noise when turning.

Dont mow over course mulch or large sticks. Had a customer that went through 3 belts in one season. The third time it was obvious as to cause because a 1/2 inch diameter stick was neatly stuck in the clutch pulley. It had cut the belt in two.

Remove all sticks and branches larger than a pencil prior to mowing.

It is well known a single phase induction motor can change direction but that type of motor is too heavy for portable equipment and a series -wound brush type motor is commonly used due to their much lighter weight.

I can think of no fault that would cause your motor to run backwards though I suppose it might be possible to fiddle with the internal connections...

One thought does occur however - as it is a variable speed tool. The speed control could be a type that outputs DC or direct current instead of alternating current and in that case if it suffered a fault that could conceivably reverse the polarity, it would reverse the motor direction.

pull plug and try motor again if boggs or still problem internal motor problem or belt- pulley causing drag turn normal need to recheck electrical system

Check transaxle bypass lever is in proper position.

There is no regular maintenance service for the transaxles. If there is notable fluid leak then likely low fluid level. See service guide.

Back firing could be an ignition, or valve timing issue, also check the function of the anti fire solenoid on the bottom of the carb float bowl ( you should hear this click as the ignition is switched on) you can also remove it and watch the centre pin retract when the ignition unit is switched on, next thing to check is that the flywheel key has not sheared, this will involve removing the flywheel, failing this remove the rocker box cover and make sure both valves are moving freely as the engine cranks, it could be a stuck valve.

* Handheld units are the most popular. Available in gas- or electric-powered versions, they're portable and convenient, yet powerful. These models can get heavy while using. Larger models can also vibrate a bit at full throttle. Consider the weight and balance of the unit when shopping. * Backpack leaf blowers are gas-powered. The blower fits in a harness that's worn on the operator's back. The hose reaches to the front where the user operates the throttle and blow or vacuum tube. Backpack blowers are normally used in larger areas. * Walk Behind leaf blowers cover the most acreage. Mounted on wheels, these gas-powered machines are normally the tool of choice for commercial users, but for regular homeowners, they can make short work of a home lawn. Vacuum units use a hose for picking up debris.
