Welcome V., Whenever you ask about a problem on a machine you need to provide us with the chassis product and engine label information. We have no idea how your machine is configured and there are thousands of possibilities out there. Most problems like this start with a weak/bad battery and...

Hello M., The tricky thing to always watch with 2-stroke engines and a compression test is the muffler "coking" up with unburnt fuel/oil. I have revived quite a few weed eaters that other shops condemned by removing the muffler and heating it up red hot to burn out the carbon waste. As a basic...

Hello C., Snapper has made thousands of models over the years, and it is difficult for my crystal ball to envision what you have. A model number and a couple of pictures would help?

There are older cheap ones that have a rubber tip, and you would hold it by hand in the spark plug hole while cranking the engine. They would do in a pinch but were not very accurate. Another type has the thread in adapters and a rubber flex hose; they work pretty well. They are also the most...

At this age, that is sound advice to replace all of the hydraulic hoses.

When I was a service manager at a local JD dealer, the small engine and rider customers consumed much of my time with "stupid". JD and aftermarket warranty were both difficult to get approvals through and of course the customer feedback survey was a tool the customers abused often. Many of...

Hello K., Welcome newbie. It always helps us understand what machine you have by providing the chassis label and engine label information. Not all machines are built the same. This also help reduce endless run on postings with a bunch of people guessing. My observation of your problem from a...

I like to compare wiring schematics to a roadmap. Not all of the "roads" are on a map, just the ones that the design artist thought were important at the time. Old "country road shortcuts" are often not on a drawn map. Along with that, I have not met an engineer (yet) that took the most direct...

Darn! I've been checking and everything has come up sold so far. I will give these a try. Red metal one ordered, and I hope it will fit. I will update once it comes in.

I learned early in my career as a mechanic to never underestimate a ground or the ground connection. They cannot be trusted by looks alone.

Hello sgkent, It is a 26086 (series 6) that someone put a 30" deck on. From what I have found so far part#7037334 should be the correct part.

I got my crystal ball back from the shop today. It showed me a Toro rider when I was looking for Husqvarna rider. LOL Have you checked the old grease you took out? That stuff is sticky and will hide small parts easily.

I will suggest that the ground not being present, the control circuit looked for a new path. I've seen this happen many times working on automotive systems especially windshield wiper motors.

Hello MParr, Many of these has a rocker arm actuated fuel pump or a pump on the side of the block down low. I have not seen any modern Kohler/Rehlko horizontal engines that are gravity feed, but I see new things all the time. This machine apparently has an electric fuel pump mounted on the...

Hello T., We are not here to beat up on people, but everyone needs understand that without the machine and engine label information we are just going in circles and guessing. Personally, I hate to guess. Parts Tree shows and entire tank, but no separate pump and sender unit...

In this situation I recommend you pull the carburetor off and remove the fuel bowl, then the float. Inspect the tip of the needle for damage. There is also a chance that some debris got into the fuel inlet and got stuck in the seat. Make sure the float is not full of fuel, if it is, it needs to...

Here is a parts source that may help you. Most likely suspect is the contactor that powers the actuator. https://www.partstree.com/models/2691676-00-simplicity-conquest-52-garden-tractor-25hp/electric-lift-group-6/

Provide the product label information off of the chassis and the engine information label. Otherwise, we are guessing. In this day and age, no two mowers are built the same for any reliable amount of time. I don't recall these coming with an electric fuel pump. Was that a hardware store...

Does this model have a throttle control cable and lever, or is it designed to run at one fixed high speed? What is the product label information on the chassis of the mower and the information off of the engine label? Without the actual label information, we are just guessing.

This has 3 basic safety switches: Clutch/brake, PTO and seat. There is likely a problem with a switch or the wiring that connects them. Here is a diagram I found: https://www.partstree.com/models/425620x92a-murray-42-lawn-tractor-2004/electrical-system-2/

Hello ILENGINE, Glad you resolved it. It's always an adventure to come in behind a DIY who thinks swapping and moving wires around will "fix" something. It's likely the wire came out when they pulled on the connector. Then they just shoved it back in the first empty slot they saw. I have that...

Kerosene heating stove oil with ATF works well and can usually be found. Diesel fuel and ATF also work well. Yes, pour it down in the cylinder and let it seep in. It also helps to rock the piston from side to every now and then with the end of a hammer handle. It will be slow, but that is the...

Looks like a pretty good candidate so far. I recommend you get some fine sandpaper (400 grit) and a tempered glass tabletop (or similar true flat surface) Lightly sand the head mating surface smooth in case it is warped a little. Go back together with a laminated stock head gasket. As for...

Hello Rivets, Back in the late 70s when I started out, I thought all Lawn Boy push and walk behind mowers 2-stroke, but I also forgot that they had a 4.5hp Tecumseh version. They even had a few with Briggs and Stratton up until they quit making them. I had to do a little research and search...

If I am not mistaken these had a square red box style plug in diode that would go bad and create a circuit feedback issue. Locate the diode under the control panel and unplug it to see if that corrects the issue.

A Lawn Boy with a Tecumseh? Welcome Newbie: Before we jump into blind guessing and wasting your time and money, we need to know the information off of the chassis label and the engine. We have lots of experienced people, but most of us retired our crystal ball years ago. We need machine data...

Good deal, glad it was something simple. This engine design has developed a bad reputation over the years. Watch for any oil leaking from the top cover area and running down the block. That is an early sign that the case bolts have loosened up and need to be retightened. If the bolts are left...

"The rest of the story" There are way too many stories that are only explained after they are challenged these days.

We need the info off of the product ID label on the chassis

The stock seat is not a spring ride seat. Any aftermarket spring ride seat would likely sit too high for an operator. One conversion that I have done over the years to some machines with a flip up seat mounting plate is to remove the rubber bumpers and install a pair or old car engine valve...

Hello W., Exmark (Toro) does not require a special oil for their diesel engines, that would be market product steering which is illegal. Use a good brand such as Shell Rotella and change every 200 hrs. under normal conditions. If it is extra dusty conditions, change it more often along with...

Find the product ID label on your mower and look up the parts on Parts Tree. No, a JD 48" deck is not the same as one on a Husqvarna. Even JD had different 48" decks on many different models.

Pictures are of 2 different machines, but the same model? AI generated ad for a money scam? These were a bad design from the start because they used the engine oil to also run the drive system hydraulics. They were the "zero turn" mower of their day before better designs came along. This thing...

The engine stacked pulley does get a wear groove in them with age and high hours. Other considerations are a stretched belt, especially if aftermarket, or a tired main belt tensioner spring. I have had older units that I had to add an additional tension spring to.

Hello M., Kohler K310? or K301. Is there and ID plate on the engine? Just like any machine, it is built using components and major assemblies from outside sources. The service manual for the engine itself should be fairly easy to find. The service manual for the transmission may be more...

Can you attach a picture of the tank fitting you are struggling with? Not all parts diagrams will break down each individual part.

Hello M., My advice is don't jump into buying parts or contemplating a "rebuild" until you have a full evaluation of the entire machine. These projects can be a joy to work on, but surprises do happen. Keep in mind that this thing got parked a long time for a reason. Considering looking into...

Hi Star Tech, The days of actual "Chem Dip" are gone only to be replaced with a useless, bad substitute for more money. I'm waiting for carburetor spray to be banned next.

Hello S., You likely have a B&S Exi725 on this trimmer? They only run at one speed. Carburetor dip is "overkill" on these carburetors. It will not hurt them, but there is very little to ever go wrong with them except the center insert with the jets or the float needle gives out from Ethanol...

I agree Stihl has saturated the market, but I noticed their actual training of techs has been pushed to quick online classes with no instructor led training. The newer Stihl products are not as robust as their earlier models. Same clothing, but weaker internals.

I guess everyone develops a fondness for particular brands. I once like the early Ryobi straight shaft trimmer combo along with the Green Machine 3000. They were powerful and dependable machines for their time. Stihl is very popular around my area, and I only see a few for service once in a...

I guess if one is bad that makes them all bad?

I've never seen a sponge like that in any Stihl FS56 I have dealt with. This looks like and "oops" part that got in there

The Z425 has always been a good light duty residential mower and not too difficult to work on. It has less "bells and whistles" to fuss with. The biggest problem that I recall was people failing to remove the engine fan shroud and keep the cooling fins cleaned. Keep in mind that the chassis...

Sounds like a bit of water in the fuel. Put a little 60% or 80% rubbing alcohol in the fuel tank and see if it clears up. Isopropyl (Petroleum based) alcohol breaks up small amounts of water. Ethanol (plant based) alcohol that is in modern fuel actually collects moisture from the air when left...

Not sure why ATF came up early in the posting. If the manual says 90W then that is what you should use.

Look your engine numbers up on Parts Tree and you will find the short pulse hose that goes to the valve cover.

Have you tried disconnecting the points ground kil wire? Most engines can be switched/updated to a none points ignition magneto. Star Tech may have the updated part number for this engine. This shows to be a cast iron block. Original coil number was 298968 according to my early quick...

So, do you have a manual shift trans with a hydrostatic unit, or just a manual transmission?

What kind of meter are you using and are you finding this by doing a voltage drop test with power applied to the wire being tested?
