SOURCE: nannie what can be wrong with my power devil

Check air filter, check screen in bottom of fuel tank,
New spark plug and also check the spark.
If there is a weak spark, the coil may need to be replaced.

If you have good spark, clean air filter, and clean fuel tank screen, then the carberator will need to be pulled of and cleaned out with solvent

SOURCE: I put new spark plug

Your mower has to have these things all working in unison to start 1. Compression (the engine has to be in good shape) 2. Clean Air (Check Air Filter) 3. Clean,fresh constant fuel supply (Maybe remove bowl of carburetor and clean/check for debris and/or water). 4.Strong Spark (Remove Plug and ground the body against the engine. Pull starter and check for nice, blue spark.
Sometimes, the problem is as simple as the brass bolt that holds the bowl on the bottom of the carburetor is clogged and needs cleaning. That's because this dual purpose bolt is ALSO the main jet. So if you remove it to clean the float bowl, clean the bolt as well. Use no metal objects on it at all. There are small holes in bottom and along the sides that get gummed up when fuel dries.
Carb/Choke areosol spray cleaner will clean the bolt. Remember, don't scrape it up.
Check all these things. To maybe "coax" the engine to run, remove the spark plug and spray a couple of shots of carb cleaner into the engine. Immediately choke it and pull start.
Some OHV lawn mowers are difficult to start because the overhead valves need adjusting periodically. The Briggs and Stratton website have instructions and specifications for doing this. It is not real complicated and allows for easier starting and much better running. Post back if needed.

Hi
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 pulling the crank rope, if you are getting a nice blue spark then:
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:
Mark each piece with a awl, or some kind of 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 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 condition after a while they will degrade and need replacment.
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 to how the lines are connected to the carburetor.
Make sure you are using fresh fuel.
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.

I've recently inherited a power devil 3hp lawn mower i am a mechanic by trade so i uderstand engines but after using the mower a few weeks ago there was alot of vibration when running now i've come...


Vibration is normally from a poorly balanced blade, a loose blade, or the crankshaft is bent due to striking an emovable object on the lawn, check all these points, if it has been like this for a while it may well have sheared the flywheel key now, if it snatches on the starter rope it is the key or a loose blade.

Was using my toro lawn mower when big clouds of white smoke started to come out of it. I put oil in the oil tank and it started to pour out the air filter. How is that? Now it won't start at all.


You have big problems my friend! You have blown a head gasket, or broke the rings around the piston. The gasket isn't as bad as the rings. But neither is a good sign. It may be time to get a new mower; sorry for the bad news..... :-(
