Please provide us with the model and serial numbers for your mower, so we have an idea of which of the 25+ different setups Toro mower you have. Second, where is the fuel leaking, tank, carb, manifold or fuel line.

I see that you have been around this forum for 10+ years, and have posted 5 threads. I think you wound know that we need model numbers before we can help you.

Two things I would be checking with this problem. First, what size battery do you have n this unit? With an engine that large you need a battery with at least 350CCA. Second, check all connections in the starting circuit. I’d be looking for a loose, dirty or bad connection, particularly in...

Does your mom’s cousin’s, sister’s neighbor smoke, if not then the cause is good upbringing.

I’ll take the bad grammar anytime over the people who fail to provide us with the info we need to help them. They then get mad when we don’t provide the answers they want to hear. Thegrammarpolice are locatedontheSocialTruth forum

That is the big question, as everyone is going to be different. Best to get on the phone and check with your local shops, as labor rates are different and it will also depend on how busy they are.

Glad to hear life is good. May I suggest that you change to oil after about 5 hours of use to remove any debris from the sump. Totally up to you.

I’m betting that you will find a parcially sheared fly wheel key.

This manual will tell you how to properly check and troubleshoot the charging system. https://www.mymowerparts.com/pdf/Kawasaki-Service-and-Repair-Manuals/FH601D-FH641D-FH680D-FH721D-KAWASAKI-SERVICE-REPAIR-MANUAL-99924206002.pdf

Have more questions than answers. Before ordering any parts please help us. 1. Please supply us with all engine numbers. 2. Did you measure the cylinders with a telescoping and vernier? Two measurements at top, middle and bottom, 90 degrees apart. This will tell us if you need to go with...

To me it’s a classic example of a blown head gasket. Since you say you had the heads off I suspect 1 of 3 causes. Head and block surfaces not cleaned properly or head warped. Reused the head gaskets, that’s a NO, NO. Head gaskets not torqued in proper sequence or torque.

MTD now builds the Cub Cadet brand so anything you purchase with that name on it will not be of the quality you used to expect from them.

Can’t be raised, must be removed. Since you didn’t supply us with the model and serial numbers for the unit, I’ve just attacked the newest service manual to help you out. https://www.toro.com/getpub/182206

I suggest you take the brake material and arm to a good body shop. They will have the best glue available for jobs like this.

I hope that when you said you honed the cylinder “as smooth as glass” you didn’t mean shiny smooth. If you have no cross hatching your new rings will not seal properly and you’ll soon be burning oil.

If it came to me the first thing I would do is pull the float bowl and see what the condition of the carb is. If it was sitting that long debris in the carb may have float around clogging the jets.

I suggest you start by adjusting the valve clearance first. This service manual will help you with that. https://www.mymowerparts.com/pdf/Kawasaki-Service-and-Repair-Manuals/FC290V-FC400V-FC401V-FC420V-FC540V-KAWASAKI-SERVICE-REPAIR-MANUAL.pdf

Before trying to circumvent the electrical system to solve the problem, I suggest you go through the electrical troubleshooting procedures listed in this service manual first. Can you do what you are suggesting, yes anytime is possible, but the fuel injector solenoid is run through a control...

Make sure you installed the proper replacement PTO switch. They may look the same, but terminal may be different. This I’d especially true if you purchased off FleaBay or AutoScam.

Any good repair shop should be able to get this part for you. https://www.partstree.com/parts/kawasaki-92055-0892/

Because you were able to free it up using a block of wood and hammer, I suspect that the rings are fine and that the rod was probably frozen on the crankshaft. If you get it running I suggest you change the oil after 2 hours use to remove any debris in the oil. No need to put any oil in the...

If you try putting oil in the cylinder do it very sparingly. Now that it is free really don’t need to, as the engine oil will start doing its job. To much oil at this point will not allow the plug to fire.

Thank you Star, it come so natural that I forgot about that.

Sounds to me that the mower was run without oil. After it seized the user put in fresh oil to hide their mistake. Sometimes these units can be saved, but your odds are 50/50. If you want to give it a try, this is what I would do. You really have nothing to lose. 1. Remove the spark plug. 2...

First thing to do is check the oil level, no oil probably seized. Has oil may be seized, but need to check further. Remove the spark plug and try again with no plug. If it turns over reinstall plug and try again. Let us know the results of you tests and we’ll tell you how to proceed. When...

This is the tool I use, but it doesn’t work you’ll have to install a heli-coil as stated...

If you are getting 0 VDC you will need to start checking all connections between the key switch and the solenoid, this includes all safety switches. Before doing that check to see if you have 12VDC at the B terminal on the key switch. IF 0 VDC at the terminal of the key switch, you’ll have to...

Have you tried using a nickel instead of a quarter, sorry I couldn’t resist. Have you tried bending the edges of the foot down a bit with a pliers to close the gap and increase the tension on the leg.

Provide us with model and serial numbers so we can identify which unit you have. The good techs on this site hate guessing.

5 hours, then use whatever oil you would like to use.

I have found that sometimes using a torx wrench will grab. Not best way to do it, but sometimes you need to think out of the box.

When I run into a unit like yours I remove the battery and then I use jumper cables to reattach the battery wires to the battery terminals. This allows me to access the solenoid for testing. Second, if you are not getting voltage past the solenoid you won’t have voltage to activate the fuel...

Change after 5 hours and you’re ready to go for the season. Today’s valves and rings on small engines don’t need multiple changes for breakin. Save your $$$$, oils going to get expensive.

First thing I would be checking are the battery terminals for cleanliness and tightness. Second would be the ground to chassis connection, clean and tightness. Here is the troubleshooting procedure I use. Electrical problems can be very easy or very difficult, depending on four things. 1...

Before digging deeper into the possible causes, I would check the valve clearances on all valves. It does sound like a fuel issue, but let’s look at the easy things first.

This site has the carb you will need, but I recommend a little more research before spending $$$ on it. I’ve seen this many times and most often I’ve found the a good carb cleaning and replacing the float needle and seat solves the problem...

Please give us the model and serial numbers off the silver tag on the rear of the engine If this site doesn’t help you. https://www.partstree.com/models/20057-toro-super-recycler-walk-behind-mower-sn-260000001-260999999-2006/air-cleaner-assembly-briggs-and-stratton-122672-0192-e1-0/

West of Lake Michigan, east of the Mississippi River, south of Lake Superior and north or the noisy state. Sorry that’s as close as you get. Got to keep some things quiet.

This manual may help you out. https://www.mymowerparts.com/pdf/Kohler-Service-and-Repair-Manuals/Kohler-Service-Repair-Manual-Courage-SV470-SV480-SV530-SV540-SV590-SV600.pdf

Ok, now that I know which engine you have, I’ve got two suggestions for the to try. First, as stated you should check to see if the choke plate on both carbs are fully closing. If not you need to adjust the throttle control. Second, I would be checking and adjusting the valve clearances on...

I’ve been working on engines for over 50 years and have never heard of an accurate way to test spark plugs with a multimeter. If I think a plug might be bad I just change it.

Ok, now I feel like a fool, because I ASSUMED what was posted was the truth. Another DIY got me to fall for the switch and bait trick. Looking back I should have realized that things weren’t really as posted. Clue was when he stated timing doesn’t affect spark, good mechanic would know...

I’ve gone to my archives and there are a couple of things you should know about the AV520 engines. First, the AV520 engine was only built as a 3hp engine in 1975&1976, before and after that they were 3.5hp. Second, they were made as an outboard engine, Eske manufacturing was the primary user...

Sounds like you need to adjust the governor. This manual explains how. http://www.gaaged.org/docs/sidemodules/38782_276781SingleCylinderOHV.pdf

You must understand the relationship between the points, condenser, and coil which most work together to produce voltage to cause a spark plug to fir. Timing on the Tecumseh engines with the magneto and points mounted under the flywheel will affect spark. Incorrect timing on a small engine...

You are assuming that the old points gap was the same as what the new points gap is set at. We’re talking thousands of an inch which is very critical. I’ve seen Tecumseh engines run at point gaps ranging from .016“-.022”, depending on how the timing was set. Also, your condenser may be bad...

Sounds like you have a coil which has either a hot short or hot open condition. Next time it happens immediately check for spark.

Not going to get into an argument how the old Tecumseh ignition systems work. Bye.

Sorry, but you are wrong. The cam may be keyed, but the timing is adjusted by moving the magneto assembly. Trust me, I grew up with these engines.

Sounds to me like your timing is not correct. This will happen if you removed the magneto assembly. Timing these ignition systems is not easy unless you have the proper dial indicator. It can be done without the indicator if you have experience in how the indicator is doing its job, but does...
