We really need the product label numbers off of the label on the bottom of the seat assembly The tiny aluminum gadget with 3 wires connected is to voltage regulator. Unplug all of them and see if it still blows the fuse. If it does blow, you have likely got a problem with the electric PTO...

I see this happen often on several models when the parents try to let the kids mow with their rider. Of course, the first request is to bypass the seat switch. MY answer is NO! and I will not give them any wiring information to attempt it themself.

Need the product label tag information. This favors a restriction of the fuel tank valve outlet screen or possible water in the fuel.

Everything has to be connected, and the voltage regulator body properly grounded. Measure output to the battery at the battery, not at the regulator output wire. If it is not charging, then there is an open or corroded circuit between the regulator battery charge wire and the battery. An...

I checked the engine number HP rating, and it is around 30HP @ 3600 RPM. Maybe a pull start is not realistic on this big of a motor. What did this come off of? That round item with all the wires suggests a throttle control device.

I forgot the mention the connector for the solenoid on the bottom of the carburetor. Gently move the connector from side to side and see if the engine acts up. The pins on the harness connect tend to spread and lose proper connection over time. If that solenoid is an aftermarket, they always...

I had to recheck Parts Tree. This model may not have had a vapor vent hose. The tank shown is in plain site placed ahead of the operator console? The fuel line connection comes out of the bottom and runs to the carburetor. That plug shows to be burning very lean. This indicates a fuel...

How much play is in the piston when installed in the cylinder? Is the cylinder scored badly? Parts show to be available, but they are expensive. Parts Tree: https://www.partstree.com/models/124t02-0203-b1-briggs-stratton-vertical-engine/?msockid=0bfed40a19466eea294dc22418c86fad

Instead of focusing on quality a durability that has kept them alive and well all these years, many are leaning towards "options and electronic gadgets" that fail in a very short time. I think we will suffer from this for quite some time to come. The term I hear quite often is "shrinkflation"...

Pictures would help. Do you have a tool to measure the plug gap? Plugs seldom come with the gap set correctly for your engine. Is it excess black carbon buildup on the plug tip? Nothing wrong with Champion plugs unless they are counterfeit. Ran great for 15 minutes then started to stall...

I will suggest tire chains. I actually used ones off of a Datsun 210 years ago for "mudding" my rider after I cut a link or two out of them and attached them. They worked great in the winter on snow and ice as well. The other option is a small trailer with weight loaded at the front, so the...

The engine identification information off the label is needed for accurate information. Does the engine lose power when this occurs? Is this water cooled, and you are just hearing the cooling fan cycle on?

The Tweels hold up. The others have been taken off the market from what I can find (sorry nothing official), so the dealer is likely installing an old stock they happen to have left. If one has broken out, the other one is not far behind. Foam filling stock tires is an option, but the machine...

Hi sgkent, It's known around here (in South Texas) as unemployed, past prison records, no steady job, "will work for food" and low (cash only) wage people who can drive anything with gears. Hay hauler trucks do not have to run DOT stickers; they just run Texas exempt farm tags. The drivers...

Hi sgkent, I work on a lot of hay hauler big trucks along with other equipment and I had one truck come in with a chronic lack of power and stalling under load. I pulled the 2 large diesel filters, and one had a section of a plastic shopping bag stretching out of the filter housing has I...

Need to find the product information label on the chassis of the machine to figure out how yours is built. https://www.partstree.com/search/?type=model&term=craftsman+lt1000+1iding+Mowers&page=1&msclkid=628bfd9ffc2b1e3cfab2955f991330f2

That is also known as a "love tap". LOL

Hello G, "You are getting warmer". Clean the valve rocker cover off. there will be a set of numbers stamped into the top (unless someone has had it off and now it is installed upside down) These numbers provide the B&S engine information only. That label under the hood is a convenient common...

Drivebelt or deck belt? How many hours are on this? Is it stored inside, covered up, or left out in the weather? Run it until it breaks or starts chunking out parts but have a new one on standby. Usually idler and tensioner pullies are needed by then as well.

Being that it is an encased unit, I would see about getting a new one or one from a different mower. Throttle cables can be problematic at times because they will bend or kink inside the enclosure due to faulty sweep angle design of the lever. If you look up the stock part you will likely find...

Go to Parts Tree or Jacks small engine to get the correct parts that fit. The dealer will be stupid expensive due to inflated markup.

First come the original manuals which everyone seems to get but then come amendments and corrections that no one hardly seems to get.

Not to spoil your project, but this bigger engine is serious overkill. Is the crank to correct diameter? Frankly, I suggest nothing over a 14-15hp and stay with a pull start to keep it simple

We need the product label information and the engine number information. The LT1000 came in many design changes through the years and just guessing never works.

Have you tried a little more hand pressure on the lever to overcome the stop? This may be an intentional design issue to indicate where the choke would be activated. It also helps people realize when the choke is still on which would cause excess fuel use and spark plug fouling.

I have to ask why do you want studded tires?

Don't place too much faith in your coolant pressure tester if is aged. I just discovered all 3 of mine were leaking at the housing assembly threads (Stant brand testers). If you tested under pressure the level should have risen quite a bit.

Hi macdoesit, The trouble is that it only takes 1 drop of water getting caught in the fuel bowl to disrupt fuel being drawn in by the carburetor jets. Water is heavier than gasoline and they are totally opposing liquids.

Has the oil level risen significantly after being run for a while? That is the most obvious way to tell. If they are checking the oil right after it has been run there will be aeration in the oil for a little bit of time. The oil needs to be checked when cold. Another way to determine if it...

That looks to be beyond saving, the seal groove and aluminum scoring tells me this thing was run low on oil. Here is a used long block engine I found on Ebay...

Hi slomo, I call BS on the drain plug rusted in place story. It was likely severely overtightened in the past and the threads were galled, or the impatient lube jockey cross threaded it. When I first started out as a mechanic in Virginia in the 80's I was actually taught to always install a...

I would suspect head warpage and compression pressure blowing past the head gaskets into the valve pushrod area. (That goes straight into the crankcase) Rings are a seldom failure unless they are smoking badly and have scored cylinders due to excessive dusting and poor oil changes.

What was your leak down test gauge showing? I ask because you cannot always trust what the dip stick fill tube is indicating. Was this engine a "smoker" before the pushrod incident? Was the head releveled by sand with fine sandpaper on a true flat surface, and a new head gasket used during...

How did you determine bad rings? Are the cylinder scored?

Pictures of your concerns would help us help you.

Hello JoeKarpowski, Minor surging at idle is a sign of a dirty carburetor internally. The carburetor would need to be removed and properly cleaned. If you want to attempt this, I can only recommend watching some videos of people who work on small engine equipment for a living. Sources: Teryl...

This poor thing has lived a long life. Sorry, it's time to let it go or find a better engine. There is no "polishing" that will save the crank journal and bearing surfaces. All that does it take metal away and increase the oil clearances. After that, the connecting rod will likely break and take...

Two things happen when you apply power to the wrong circuit. One is you let the "magic smoke" out and two, you likely created more problems than you started with.

Have you ever worked on a carburetor before? They are not to complex, but you need to take pictures as you go. The top cover has to have the screws carefully removed, to inspect the inside of the carburetor bowl.

Hi StarTech, I also had a couple fail years back because they were too thin, but the last one I got was a thicker and improved design.

When you initially reset the governor adjustment, it likely had enough room to allow the governor center pin to pop up out of place. Hopefully it is a simple fix and a new gasket, and you are back up and running. Note: Use only a Briggs and Stratton sump gasket kit. Amazon gaskets will create...

They are push on speed clip retainers Sometimes you can find them at a NAPA or a parts store that has selector boxes of various sizes. Occasionally they can be found at a good hardware store. A good small engine shop would have them, if one can be found in your area. It helps to remove the...

The governor has only one job and that is to "govern" (control) the top running speed (RPM) of the engine, that is it, end of story! No starts or surging have nothing to do with the governor operation. Governors do not require adjustment once they have been set during initial factory assembly...

This is a lawnmower forum, not English 101. Many people have terrible writing skills, and they always will.

That is not the number. Look at the flat vertical section opposite side of the block from the air cleaner and carburetor. They will be dot etched numbers, not casted.

Hi Phillybo, The manuals do not give the exact design specification for the installed height of the valve guides. If this head has a pushrod guide plate mounted below the rocker arm retainer bolts, be sure to check them for excessive wear in the area that pushrod comes through. These are often...

If not you first succeed, try, try again and again and again.... That free returns thing must be intoxicating.

They are not that failure prone unless it has been run with a dead/bad battery for a very long time. The charging system on these are only meant to maintain the battery and run the PTO clutch and lights as need. Thy are not meant to constantly recharge a bad battery. If it mounts to the plastic...

Helo Phillybo, Have you compared it to the other head to verify what is going on? Often times a pushrod get bent on these when the valve lash is too far out of spec. The pushrod come to the edge of the rocker cup and it binds up on these.

"Necessity is the mother of invention" (Plato) That looks pretty interesting, but it works and that's what counts Now you need to take a little clear silicone and seal up all the exposed connections to prevent dirt and moisture from creeping in and ruining your progress. I take it that the...
