First pull your spark plug out reconnect to the plug wire and ground tot he engine body
Pull the starter cord and see if you have a good clean spark that goes to the electrode and not to the side of the spark plug.
If no spark check your off/on switch

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.

Why won't my 1998 Polaris indy 500 start? It is getting fuel and has spark.


Along with fuel and spark...you need enough spark and you need enough compression. Asssuming your rings aren't broken and you can feel good compression when you are turning it over, you can spray a little ether in the carburetor chamber. If there is enough spark and compression it will at least fire up momentarily.
Sometimes the rings or cylinders get scratched up because they run incorrect gas/oil ratios for too long and then when they sit for a while the oxidation fills in those scratched surfaces. Starting with high fuel to oil ratios is easier to start ( gas burns easier with less oil in it) but the engine will wear faster with high ratios.

But if the engine won't start under pure ether, then the spark is real weak or out of time, and/or the compression is shot. Good compression makes heat and concentrates the air and fuel together. If the compression even falls from 10:1 to 8:1, that is enough to cool the charge from about 150F down to about 90F or so and you won't get ignition

WHEN I GIVE IT GAS IT START TO MISFIRE


Misfires are caused by one of 3 things-gas, spark, or compression-one of those is the problem. For gas, check the fuel pressure and see if it is at the right pressure for your car. Low fuel pressure will cause misfires. If pressure is good, it could still be an injector problem, like a clogged injector. If low pressure, suspect the fuel pump or the fuel filter.
For an ignition spark problem, check your spark plugs. Pull them out and inspect them for broken or cracked plugs, check the spark plug gap, check for oil fouled plugs. You may be able to isolate the misfire to a cylinder or two by the plugs condition. A misfiring plug or cylinder should show more black, sooty deposits than the other plugs. A normal firing plug will have a tan or brown colored insulator on the end with very little deposits. If the plugs are okay, clean them a bit if needed, and check for spark on the spark plug wire ends with engine cranking. Buy an inexpensive spark tester, or hold each spark plug wire metal end terminal 1/4 inch from a ground on the engine block, while cranking the engine. Wear a heavy glove to avoid getting shocked. Check that every cylinder is getting a strong blue spark to eliminate ignition as a problem. A weak, yellow or orange spark is an ignition problem, possibly a bad coil, or other ignition part.

If spark and gas is good, you may need to check engine compression. Any cylinder that has significantly lower compression than the other cylinders will cause a misfire, and set a misfire code. You should check for any trouble codes in the engine computer. A code reader or scanner would have to be connected to the diagnostic connector under the dash. What is "significantly lower" compression? About 15-20% less compression. Say you checked and had 150 psi compression in most cylinders. If one had 20% lower compression ( 150 X 20%= 30 psi, 150 -30 =120 psi, or same as saying 150 X 80%= 120 psi.), a condition like that can cause a misfire. I hope I have made sense here. Good luck, and post back what you find, or if any questions.

Won't start has not been started in five years, has new gas,new oil and new spark plug


The carburator may be empty. Open it and fill it with fuel before starting.
Other way is to get a starter spray, open the input collector or where it is possible and spray while starting.

My model TB46599, less than 1 year old, has no


Absolutely. What sometimes happens is that carbon will build up on the cylinder head. Then when you try and start it you get a mini backfire and it knocks the carbon loose. The carbon get mashed under one of the valves and then you end up with no compression.

Here are a couple of things you can do to try and loosen it up. (Mind you that you will have to change oil after this and probably need a new spark plug.)

1. In a well ventilated area... preferrably outside and off the grass or any vegitation area, remove the spark plug and turn the engine until the piston is all the way to the top. (TURN OFF THE FUEL SELECTOR)
2. Then dump about 3 cap fulls of oit into the cylinder head via spark plug hole. (Cap from 1 qt small mouth oil bottle)
3. Pull starter cord slowly 2 times.
4. Fill the cylinder all the way to the top of the cylinder head / spark plug hole. Keep it full for about 10 minutes. Add more gas if you have to. The goal here is to soak the overhead valve seat with raw gas for a bit.
5. After 10 minutes... YANK the starter cord with ign off knowing full well your going to make a mess.
6. Add Fresh gas to cyl head (not full this time) and YANK the cord again.
7. Keep pulling cord until vapor / gas cloud stops exiting spark plug hole.
8. Install spark plug and check compression.
Good compression... Good deal.. CHANGE THE OIL because it leaked past the pistions rings during the soaking process.

Still no compression the head will have to be removed and the vavle seats hand lapped with grinding compound.

NOTE: Before turning on the ignition switch... and attempting an engine start make sure that the unit is not soaked in gas i.e do a good clean up job.

Safety First!

Thanks for using FixYa.

Ran great sat. but would not start sun. same gas changed plug air filter gas soaked with it off still not running tried putting gas in spark plug hole still not running this is a craftmans 2 cycle leaf...


Were you running a fuel mixture of 40:1(3.2 oz of 2 cycle oil to 1 gal of gas), that you mixed up before you started using it again. The unit may have had to much use on Saturday and may be burned up. Try to have a compression test done on the engine, needs to be at least 100 psi to run. If that proves to be good then you can start looking at Fresh gas mixture, a new spark plug, Carburetor rebuild or an ignition module.
