This means you have a leak that needs attention. If you do not know where it is coming from you need to take it to an expert. It's too easy to assume you know but get into an expensive job if you play with it. I know as I have been there and done that.

have you tried a different spark plug? if not that then check the ignition coil supplying spark to the plug thats fouling

Have had only bad lifters to cause that problem.

Intake is .004 in. and exhaust is .006 in.

Very common problem needs carb rebuilt or clogged, just not getting fuel.

Hi Victor:For parts and they have a phone number you can call.http://www.jackssmallengines.com/

Check the oil to make sure you don't have gas getting in your oil. If that's not a problem then you may have a leaking head gasket.

might have bad gas or dirty spark plug check the gap on your plug and maybe the coil

if electric start could be the starter solenoid or flat battery try jump start maybe first

Hi mbeaudoin110 Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting a bright blue spark at the spark plug.You do this by grounding the plug on the head of the engine and cranking the engine or by pulling the crank rope...watching the plug for spark.If you are getting a nice blue spark then skip A below and go to B. A...If you do not get a nice blue spark then you may need to replace the electronic module.Note: If you have to replace the module be sure to measure the position it is in, it is critical to starting.Take a picture for later reassembly. B...Also take some fine grit sandpaper (not emery) and lightly sand the flywheel where the magnet is located to clean any rust or corrosion from the magnet area.Then follow the procedure below:------------------------------------------------------------------------------------Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible. Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel. Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT. Note:Before you disassemble the carburetor:Write down on a piece of paper and or take a picture of how the linkage attaches to your carburetor for later reference when you go to reinstall your carburetor.Mark each piece with a awl, or some kind of sharp instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it. Sometimes you can get by with priming the carburetor or by using a very small shot of starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line/s condition...after a while they will degrade and need replacement. Check/Clean/Replace your fuel filter if you have one.When you remove your fuel lines from the carburetor be sure to make a drawing or take a picture of how the lines are connected to the carburetor.Also a good time to take a picture for later reference for reassembly. If the mower is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc. When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.Once you have your carburetor cleaned/rebuilt that should solve your problem.Please take time to rate me Bud

Starters burn up eventually, just had similar experience and I took the starter off to inspect and the magnets inside were broken off the wall of the starter and it would not turn. Age is a factor in most starters, these get hot being mounted on these small engines and don't last forever in most cases. Good Luck!

Make sure your air filter is clean, if it gets dirty and or plugged then it causes it to **** oil out of the crankcase through the pcv valve

perform a compression test low compression will not draw in fuel into the cylinder see them blow head gaskets around 2500 hrs

do a compression test just did another kaw 23 blew both head gaskets

This may or may not have anything to do with it however I have the same engine on my Cub Cadet Enforcer and what I found to be the problem was a wire to the saftey switch under the seat had broken. This made it sound like an engine problem by making and breaking contact as I was mowing. My first thought was a fuel filter stopped up as it was sounding like it wasn't getting fuel because it was OK when I was stopped and the engine wasn't loaded.

Check solenoid on the back of carb! I just had a similar issue with the same motor, would start rite up but had no power! new fuel pump coils, plugs ect I found the ground wire going to the coils were zip tied to manifold and rubbed through on the underside of wire never saw it 2 days later ripped it apart again and bingo found it taped it fixed problem.

see if your loosing spark when it dies could be a bad coil

maybe you have a carb problem and that's why the plug get fouled out
