Question about Toro Lawn Mower With Toro Power Tools

1 Answer

I have a toro 620 Z, I have replaced the fuel pump, carburetor, coil, all three fuses, just to be on the safe side, and the spark plugs. I get about 13.43 v off the voltage regulator on all three leads, yet nothing to the coil. What am I missing. It was running fine and it shut off. I replaced the coil, and it ran fine for a while, and shut off again, and now will not start.

Sounds like your safety system is engaging and grounding your system. Look for a bad ground or a damaged wire on the coil or on the way to the coil that has a bare spot that may be grounding you out. I will assume that is a generic photo that posted with your question and it doesn't really show the engine safety shutoff that you hold while the machine runs. Start at that point and work your way to the motor.

My Toro Personal Pace mower will not come up to normal full idle.


If this is a Briggs and stratton engine, there should be a screw that holds the carburetor bowl. Remove that screw and look for a hole that runs through the middle of the screw from side to side just above the treads. Clean with a thin wire or maybe a paper clip. Then clean the perpendicular hole in the screw that runs from top to bottom. Reassemble and attempt to run. In my experience, if you don't have success at this point, you can buy a new carburetor on amazon for about $20. Install and your good to go.

Good luck to you!

Tip

Engines with Starting Problems


All engine regardless of manufacturer need three things to start and run. Air, Fuel and Spark, lets look at each one.

Air- this refers to air intake on four stroke engines this intake is created by the piston pulling in air with the intake valve open. You must have a combustion chamber that is sealed, meaning that there are no compression leaks from the head gasket, or from the valves. The valve timing must also be correct, meaning that the intake valve is open while the piston is going down on the intake stroke. Associated parts include the air filter, air intake manifold, intake valves, pistons and intake hoses.

Fuel- this refers to fuel supply, with out fuel an engine can not run, the fuel supply has to be correct for start and run conditions. Associated parts for fuel are fuel pumps, fuel pump relays, fuel pump fuses, fuel lines, fuel injectors, fuel hoses and carburetors.

Spark- this refers to the ignition source provided to ignite the fuel mixture. Spark is generated from an ignition coil and released in several ways. Associated parts to ignition are the ignition switch, coil, ignition module, crankshaft position sensors, camshaft position sensors, spark plug wires, spark plugs, distributors, and ignition points.

If you have a vehicle in which the engine does not run one of these three things are missing, otherwise it would work, so remember to always check the basics first it will lead you to your problem faster and cheaper.

I have a Toro snowthrower Model 38472. How do I drain the fuel so that I can put it away for the summer?


Joe, page 18 in your manual tells you what to . Drain the fuel from the tank and carburetor by performing the following steps: A. Loosen the fuel-tank cap. B. Unscrew, but do not remove, the small screw on the side of the carburetor fuel bowl (Figure 33) until the fuel begins to drain from the carburetor. Drain the fuel into an approved fuel container. Important: Do not remove the carburetor bowl bolt on the bottom of the carburetor. Figure 33 1. Carburetor bowl bolt-do not remove 2. Small screw on carburetor C. Wait for a few minutes until the fuel has drained, then install the fuel cap and tighten the small screw on the carburetor. Note: Use a handheld Phillips screwdriver to tighten the carburetor screw. Over tightening the screw could strip it and cause leaking. 5. Dispose of unused fuel properly. Recycle it according to local codes, or use it in your automobile. 6. Remove the spark plug. 7. Squirt 2 teaspoons of oil into the spark plug hole. 8. Install the spark plug by hand and then torque it to 27-30 N-m (20-22 ft-lb). 9. With the ignition key in the OFF position, pull the recoil starter slowly to distribute the oil on the inside of the cylinder. 10. Disconnect the ignition key from the lanyard and store the ignition key in a safe place. 11. Clean the machine. 12. Touch up chipped surfaces with paint available from an Authorized Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting. 13. Tighten any loose fasteners. Repair or replace any damaged parts. 14. Cover the machine and store it in a clean, dry place out of the reach of children. Allow the engine to cool before storing it in any enclosure. The first link is a download for your manual. Check the attached links,instruction and guides, Good luck

FOLLOW this steps and fix it. Merry Christmas

Spark Plug

Every chainsaw relies on a spark plug to ignite the air-fuel mixture for proper combustion. Over time the electrode on the spark plug will burn away and the engine does not start. If the engine does not start, remove and inspect the spark plug. If there is any doubt that the plug is working properly replace it.
Enter your model number to see parts for your chainsaw.

Carburetor

If the chainsaw won't start, the carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the chainsaw for a long time some of the volatile ingredients may have evaporated, leaving a thicker, stickier product that is more like varnish or shellac. This sticky fuel can clog up the small jets and ports in the carburetor and it can be difficult to burn making it hard to start the engine. The only solution is to drain the old fuel from the float bowl and thoroughly clean the carburetor with carburetor cleaner. If that isn't effective, replace the entire carburetor.

On - Off Switch

Chainsaws are equipped with an on/off switch. If the chainsaw does not start, this switch might be defective. Check the switch for continuity. In the on position the switch should have continuity.
Enter your model number to see parts for your chainsaw.

Safety Switch

If the chainsaw does no start, the safety switch - or throttle control switch - might be defective. If the switch isn't engaging with the throttle it won't provide enough fuel to the engine and the engine does not start.
Enter your model number to see parts for your chainsaw.

Ignition Coil

If the chainsaw engine does not start the spark plug may not be getting voltage. Power to the spark plug is provided by the ignition coil. The ignition coil is mounted next to the flywheel. As the flywheel spins an electrical current is induced by the ignition coil. If the ignition coil is defective it will need to be replaced, it is not serviceable.

Rewind Spring

The recoil starter assembly has a rewind spring which spins the pulley backward to rewind the starter rope. If the rewind assembly is broken the rope will not rewind and the engine does not start.

My troy built 2200 pressure washer was running fine but then shut off instantly I then noticed it had low oil I filled it but now it won't start


9224467.jpg
Pressure washer takes oil in two places:
Pump oil is 20-30 weight SAE non detergent and comes half way up/ do not fill more than 1/2 way
Engine oil is 10W30 and comes half way up dip stick
IF you overfilled the oil >>> DO NOT turn power washer on it's side or upside down to drain oil >>> because engine oil will fill carburetor

When engine won't start
We pull off air filter so we have direct access to carburetor
Spray WD-40 into carburetor while starting
The engine will fire on the WD-40

You can keep spraying WD-40 into carburetor to keep engine running while moving choke to see if engine will run on it's own
Squeeze gun trigger so water comes out gun and pump pressure doesn't stop engine

If engine will not fire on WD-40
Spark is suspect
Your spark plug gets power from ignition coil
If coil is bad you get no spark > and coil needs needs replacement
Take out spark plug, clean it with WD-40 and use a bit of sandpaper in the spark gap
Put spark wire back on plug
Touch threads of spark plug to metal part of engine > pull cord and look for sparking between spark plug and engine
If you do NOT have any sparking, then coil is bad
If you HAVE spark, then your spark plug needs cleaning or replacement

If engine fires on WD-40 but will not keep running
Then either fuel or carburetor are suspect
Loosen hex nut on fuel filter located below gas tank >> if fuel flows, then re-tighten hex
Next, pull off rubber hose connected to carburetor to see if fuel flows to carburetor
If fuel is flowing to carburetor, then the carburetor is suspect.
Small engine repair shop will have carburetor cleaners

Check exhaust
There is a screen over exhaust
Make sure it is clean of carbon build-up > Use WD-40

Change air filter

Bike will start and warm up fine. after riding till its up to operating temp (running fine) no missing , or other problems, if you shut it down, it wont start back up- it just pops, and backfires. only way...


Seems as I've answered this question before. I hope I haven't answered for you already because if I did, the information I gave you didn't work.

First off, you've got to determine why the engine is not starting. An engine needs three things to run. Compression, Ignition, and fuel. Since it's doubtful that your compression has just went away without some catastropic event taking place, that leaves ignition and fuel. So, we have to determine which is the culprit.

Ignition, if you or a friend has a spare spark plug, pull a spark plug wire off a plug and put the spare plug in there. Hold the spark plug firmly gournded to the engine and try to start the engine. Watch the plug to see if you're getting a spark. If you are, proceed to the fuel checks. If not, you need to deternine why not. Since you said you replaced the coil, did you put the correct coil on the bike? Using an ohm meter, disconnect the wires from the small terminals of the coil and test the resistance between the two connections of the coil. The primary resistance across the coil should be 3-4 ohms for an electronic ignition like ou your '93 model. If the coil checks good, there is an ignition black box under the triangular plate on the left side of the box. The service manual tells you how to test this unit but you must use the speicific type of meter they use or your readings will be wrong. So, if you're not getting spark, I'd plan on replacement of the ignition unit on the bike.

If you think the problem is fuel related, you need to determine whether you have too little fuel or too much fuel. Remove a spark plug and see if wet and smells like gasoline. If so, you're bike's carburetor is flooding for some reason. It could be the needle valve or the accelerator pump. You might try turning your petcock off when you stop the bike. If this solves the problem, you need to service the carburetor to fix the problem correctly. Rebuild the carburetor. Good Luck.

Toro TimeCutter z4200 will not start


First check to see if there is a fuel shutoff under the tank. On some models there is a fuel filter screen inside the tank where the fuel line connects to the tank. If niether of these work, R&R the carb.
