Question about Toro Lawn Mower With Toro Power Tools

Open Question

Toro z222 won't stay running without a prime.

I bought it used and got no manual. Not sure if it's fuel injected or carbureted. It hasn't been sitting for an extended period of time, this I know. I got it in pieces, the deck and pulleys are all un assembled. I'll have to figure that one out later, just trying to get it running and moving but it won't start now without spraying gas straight into the intake, It tries but no luck.

SOURCE: toro recycler will start until primed gas is consumed.

I had similar problem and cleaned the spark plug and that seemed to have worked, but I think that may be a temporary fix because the engine still seems to be running unevenly. I feel that it must be a larger problem with the carb. If anyone can help this novice to adjust the carb or clean both carb and filter, or offer other solutions I would appreciate your assistance.

The problem is that the gas that sat in the carb all winter glazed it over and gummed it up. Begin by going to any auto parts store, like an aiutozone, and getting a bottle of carb. cleaner. Seafoam is one I use. Add it to your gas, one ounce per gallon of gas. Also, pick up a can of engine starting spray.

Remove the air filter and spray the engine starting spray into the air intake. Pull start the engine and give it additional squirts of engine starting spray until it runs smoothly.

SOURCE: I have a Toro model 20007 recycler with a 6.5HP Tecumseh engine

This almost sounds like a pinhole in the primer bulb but I need to know if you did the following. Did you remove the jet and venturi tube in the bottom of the carb. and clean the BRASS orifice hole and BRASS tube holes? If you did not then It will act just like the symptoms you described. Also check to see if your float bowl nut has holes in the side of it. IF it does then make sure the hole(s) are clean. Also make sure the fuel selector is all the way ON. Adittionally if the carb to block mating gasket is torn or not secure it will also perform as you stated.

Lastly the open the fuel air mixture screw on the side of the carb about 1/8th turn and see if the performance changes.

If the problem persists ....
This is dangerous due to the risk of fire but....

If you have any carb cleaner you can give it a quick shot in the nmating areas just after you start it before it gets hot to see if it speeds up. If it does, you have a vacuum leak. It is better to use an unlit propane torch if you have one.

Thanks for using FixYa,


P.s. If the problem does persist I will need your complete engine number to proceed in troubleshooting.

Testimonial: "Thanks for the info. I ordered a rebuild kit for the carburetor so i can replace the gaskets. And i ordered a new primer bulb. The engine is a Tecumseh LV195EA-362003B 6.5 hp engine on a Toro model 20007 recycler mower. Do I need to remove the welch plugs?"

SOURCE: Toro lawn mower starts but

The engine is starving for fuel. At this point I am assuming the spark plug is clean and not fouled, and the air intake cleaner is not clogged. The idle jet passage most likely has a blockage, preventing fuel from reaching the combustion chamber. Priming the engine while it is trying to run is forcing fuel to the engine instead of the fuel vaporizing and flowing to the engine.

Hi ckjmcmillen...
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 fire 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 spark then:
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Be sure to Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
NOTE: Before you disassemble the carburetor:
Make sure you 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, normally they are located in the fuel tank of weedeaters.
When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.
Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.
Also make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the mower/weedeater 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.
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.
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.
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 rebuilt that should solve your problem.

Car has been sitting up and will not start now. It seems to not be getting gas and I do not know how to prime a fuel injection system. Any help appreciated.

There is only a few cars fitted with an ancient petrol injection system that needed any priming.

Diesel engines mostly need the injection system priming but petrol injection systems do not.

Lots of cars use a system where the fuel pump runs for a couple of seconds when the ignition is switched on and that is all the time it takes to prime the fuel system. After a couple of seconds the fuel pump switches off and waits to restart when the engine is cranked.

As priming the system takes only a couple of seconds some manufacturers don't bother with the brief priming run of the pump and just have the pump start when cranking.

Could be faulty supply, fuse, pump relay or the pump itself.
If the car is fitted with an immobiliser, perhaps that is the problem.

Starts, stops will run if you prime

Clean the fuel system out thoroughly. If carbureted (not fuel injected) clean this also, check the floats.

Toro Power Clear 418 ZE Snow Blower won't stay started

The main jet of your carb is clogged and you need to open carb and clear the obstruction - spray carb cleaner on the bolt that holds the gas container to bottom of carb - also spray all the innards along with any tube that protrudes into the gas can.

Then using air compressor blow the sucker out and reassemble. That should do it.

What model truck do you have? What engine? If your engine has a fuel injection system, and this just started happening without warning, then the problem could be your throttle position sensor. You would need to run a computer scan to verify. If it is a carbureted model, you need to make sure the choke is all the way open when it is warm, and if not, you need to adjust it so that it is, and then check to make sure the idle speed screw that sits on a cam operated by the choke is properly adjusted.
