kohler motor issues Please help

I have a Yard King riding mower, has a Kohler motor, seems like after its been sitting it starts up but only runs for like 10 mins or so or like today when I really gave it some gas it quit out on me , then doesn't start at all, I started with the the carb, took it out cleaned it up real good, made sure it wasn't the fuel solenoid underneath. I put a new fuel line and also put in a fuel shut off valve and through in a new fuel filter for the heck of it . I even put a brand new spark plug in it , now after it dies then I go to start it again the fly wheel just spins and spins kinda seems like it wants to start but its not getting fuel or spark or something to make it combust and go which is why I thru a new plug in there, im now lost and have no clue what to do, any Ideas anyone ???

 

It sounds like fuel. Take the solenoid off, ground it on the engine and with the wire still attached turn the switch on/off. The solenoid should open and close with the switch.

Do you have a fuel pump on it or is it gravity feed from the tank? If it's gravity feed disconnect the line from the carb and see if you have a good stream of fuel coming out of the line.

If you do, check for spark on a grounded plug. Look for a bright blue spark. If you do, and the fuel stuff is in order, it should start and run for you. If you still get the ten minute run time, check the fuel and spark right at the time it dies.

 

its a gravity type fuel flow deal , I know I got good flow for when putting in the new fuel line I wasn't thinking and un pinched the line before connecting the other end and go it all over me, anyways I put the new spark plug in there is it possible that the coil pack at the other end of the wire is shot ? I didn't check for spark yet wasn't sadly really sure how to check for spark kinda new at all this but what I figure out how to see if im getting spark or not, and if im not would that be the coil pack ?

 

First I would try loosening the gas cap so it's just barely on then try running the engine and see if it still dies. If it continues to run you need a new gas cap because it's not venting properly starving the engine of gas.

If it still dies after running a while (the engine gets good and hot) it could be the coil is starting to go and it dies when it gets hot but will work again when it cools. Eventually it will get to the point where it will not run even when cold.

To check for the spark remove the spark plug. Attach the spark plug wire to the plug. Position the plug so the hex, threads or tip is touching the head of the engine making good electrical contact. Then turn the engine over and look for the plug to spark between the tip and electrode.

 

Thanks I'll try the spark thing....I'm starting to wonder if it is the coil now because when I try to start it up after its been sitting and drive it once it dies it won't start back up at all till it's been sitting a good while it seems .......I have already done the cap trick

 

If the flow of fuel to the carb is good and it ran well for ten minutes or so, the chances are the spark is the problem and that would be the coil (ignition module), Those can give limited service on their way out altogether.
