Troy Built Bronco Kohler Engine Won't Start

Have 2010 Troy Built Kohler Engine on Bronco Lawn Mower
Motor cranks but won't start
New Solenoid
Good Battery
New Spark Plug
Good Solenoid Fuse
Fuel filter is good
When cranking get small spark, but you can hold with just a little shock
I've sprayed air filter with starter and gas and still no starting...just turns and turns

Remove the spark plug and put a teaspoon of gas in the hole then try to start to see if it will attempt to start. Have a good one. Geo

I already tried putting in gas into spark plug area without any success

You say you're getting small spark. Does that mean you can visually see the spark? Because normally a spark you can see will give you more than just a little shock when you hold the lead. I'm thinking you have a weak coil and you are feeling a little jolt but there is no spark.

Does it have a low oil cutout, and if so, is the oil level proper? Check the manual to see if dipstick is supposed to be screwed on or just sitting on the threads.

No low oil shutoff and the dipstick shouldn't have threads on this one.

jlivingood

When turn off the lights you can see small spark, but not easily see with naked eye.
Oil level is fine as it's plastic dipstick and no sensor.

Is the spark jumping across the electrode gap on the plug or is it jumping from the threaded area of the plug to ground?

jlivingood

spark is going on electrode gap.

cheese

Have you pulled the valve cover off and made sure both push rods are in place?

jlivingood

Yep that is next along with looking at head gasket as i have spark, gas so it must be combustion or perhaps a bad gasket. Any thoughts

Probabley have a bad coil, but disconnect the kill wire that goes from the coil to the wire harness. If you still just get a "little" shock when you hold the lead, you have a bad coil/module.

Don't take everything apart until you try that.
