throttle spring could be broken stretched or missing

First, check the fuel lines for cracks or breaks.
Second, Disassemble the carburetor and spray with carb. cleaner. Use a Den Tek Brush,
(http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152), to clean the small portals in the carb. Make sure the small screen is free of debris. Reassemble and start. If you need further assistance, just let me know.

Engine surge is usually caused by one of two things... 1) a lean condition. Not getting enough fuel. 2) throttle plate shaft in carb is worn. usually clears up when engine is put under a load. You can live with it or replace the carb

That doesn't sound like a clogged fuel line, it sounds like your carb either needs a cleaning or a rebuild. If your fuel line was clogged than you wouldn't be getting fuel to the carb and you wouldn't be able to prime it. First check the smell of your fuel, if it smells stale then you sould empty it out and put fresh fuel in.Next take the air filter housing off unless the carb is exposed enough to get to easily. If you clamp off your fuel line (unless you have a shut off) so no fuel passes to the carb., wipe down or with an air hose blow off the bowl of the carb so there is no debris, pull the screw out of the bottom of the car., be sure to use a clean container to catch the fuel and look for any debris in the fuel. You can also take the bowl off and see what the inside of the bottom of the bowl looks like. Your looking for any debris or gelling of the fuel inside of the carb. if anything is noticed then the carb. is going to need atleast a cleaning. If a cleaning doesn't work then you may need a rebuild kit. Any qeustions on any of this please feel free to ask me.

Are you refering to the solonoid on the bottom of the carb? That is an anti backfire device. It will not cause the motor to smoke. If it has failed the motor will not run; the solonoid prevents fuel from entering the main jet.There are several things that wil cause a motor to smoke. First check for fuel in the crankcase. To check for fuel in the crankcase, it is hard to see on the dipstick, remove the dipstick and VERY CAREFULLY away from anything flammable and away from the motor hold a lighter to the dipstick. If the dipstick lights it has fuel on it, a lighter will not ignite oil. Blow out the flame and wipe the dipstick clean with a rag before inserting back into motor. A worn needle or debris in the needle will cause the carb to flood. It will fill the crankcase and muffler with fuel. To cure this you will need to rebuild the carb and change the oil. Installing a shut off valve in the fuel line will prevent this in the future. After the service has been done the unit may smoke for 5-10 minutes while it burns off the fuel in the exhaust.Burning oil indicates stuck rings, overfilled oil, or worn valve guide seals ( valve guide seals will smoke on start up then clear up).Also leaking rocker covers will drip oil on the exhaust and burn off.

Hi John VitranoMake 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...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

Not a big deal. Im assuming this is a 4-stroke push mower and not a leaf blower.Remove the air box cover, air filter, and air box back plate. Careful there is a gasket on the back of the backplate that if damaged the primer bulb wont work, part # 272653. Remove the fuel line from the carb and drain the tank. Using a 1/2 inch wrench remove the bowl nut from the float bowl on the carb, hold the bowl to the carb as to not break the gasket seal, drain the bowl and replace the bowl nut. If you tried to run the unit and oil is in the cylinder remove the spark plug ( clean the spark plug) and spray some carb cleaner in the hole and pull the starter rope several times to purge the cylinder. Reinstall the spark plug, reattatch the fuel line, install the air box back plate ( leave the air filter and cover off for now), add fresh fuel. Take unit outside and start, you may need to give it a shot of carb cleaner in the throat of the carb to help it start. It may smoke, it may blow oil out the muffler. Let it run until it quits smoking ( usually around 5 minutes) . Shut it off and complete assembly. It should be fine.

Remove the air box cover and air filter. Spray a shot of carb cleaner into the throat of the carb. Try to start. If it hits and runs for a second then you have a fuel problem, ie. water in fuel, clogged jet in carb, etc. If it wont try and run then its likely another issue, either in ignition or compression.

yes since the engine sat for a time the sealing rings on piston has rusted/stuck (you should never allow any engine to sit long time ) you can try removing spark plug and injecting some automatic transmission fluid into cylinder pull engine over slowly by hand adding more fluid then allow 24 hours for fluid to work it's magic then crank engine over a few times to clear last of fluid then reinstall plug and start may require cleaning of spark plug a few times with starting fluid to remove all last remains of fluid out run engine for good 30 min to see but it just may free up that stuck ringOr you can just use it as is but be sure and maintain crankcase oil level as it will use oil and ring may unstick that way as well

The carb needs cleaning.. Has the mower been sitting for a period of time ? If so the gasoline evaporates and leaves a gummy "varnish" type residue in the carb.. Gumming up things and making them stick..

The website is a good thing go to their website have serial number ready there you will find what you're looking for.. Good luck

First thing you need to do remove spark plug wire.. Then I would go to the website for Toro have the serial number ready there you will see the full picture of the way it is then go from there that's the best way with out seeing it. Good luck

Check your fluid..... Sounds low...
