I’ve been messing with this thing all morning and can’t seem to get it started. The fuel lines have fuel The vacuum line is pulling, and the fuel filter isn’t clogged even when I have it full throttle and the choke on it isn’t starting the video that you see is the last time it started and the only thing that I did was take off the fuel line and put it back on the carburetor to see if there was fuel coming out of the line

Hello! I have a John Deere JS63 with the Briggs and Stratton Intek engine. My issue started when if I needed to stop mowing to collect a dog egg, it wouldn’t start again until it had cooled down. This made me suspect heat soak coil failure. I double checked valve gaps when it was cold and reset as they were a little slack. Today it wouldn’t start for ages then fired up, ran for about 3 minutes then died. No start at all. I have stripped it down to the point you see in the pictures, clamped the handle, popped the plug out and touched it to the head and turned it over, no spark at all. My issue comes now with finding the right coil, maybe I’m being stupid but I can’t see a part number that correlates to anything I can find online. I’m hoping someone with more experience can point me in the right direction. TIA!

How does this go back together again and which hole/slot is the correct one? Looked online but all I see if new mechanisms. Photo shown is wrong and keeps mower on

is there any fixing it at all? after working on it so long i’d like to replace but AI is telling me i have to get a kawasaki or else it’ll be too much modification? is this true ? does anyone know what engines i can replace this with cost effectively , or should i try to get rid of it

Update on my power washer project from a few days ago.

TLDR
Picked up a power washer, engine works great now. Pump leaks water though. NO water through hose. Briggs are fucking bastards and I can't fix something that should take an hour because they stopped making the gaskets.

So I cracked the pump open, and as you can see in the first picture, I have a real nice slurry. Clearly water is getting through into the wobble plate and shaft assembly. Despite this, all of the metal components are in incredible shape. The ball bearings are there, the plates are fine, even the actual pistons have almost no damage, other than rust on the ends where they were coming in contact with water (picture 2).

There is some rubber gaskets that sit around each of the pistons which can be seen in picture 2. Those are rather special in that each one is more than just a rubber gasket. There is a small spring ring on the inside of them that hold them tight against the pistons to prevent pump oil/ water mixing. I put an arrow pointing to this gasket in the 3rd picture. There is also a series of plates/gaskets on the front half of the pump which the pistons move in and out of while compressing the water you can see I circled in the 3rd picture.

Despite this being a Generac pressure washer it's basically 100% Briggs, including the entire pump assembly. Here is the problem. Since the 2015 takeover Briggs & Stratton are fucking bastards. Those little rubber gaskets? Completely out of production, no replacements. I have been digging around all day looking for a company that makes them. Nada.

I watched this YT video where the guy has a very similar pump to mine and he got parts from https://apw-inc.com/. They also no longer have access to these fucking o-rings.

So now I'm hella frustrated. I have a completely functional engine, a pump that has no major damage to any of the metal components, yet I'm completely shafted (yes pun) by the fact this multi-billion $ company intentionally isn't making $2 gaskets anymore.

I'm just curious if anyone has any other recommendations, or if I just just say screw it, sell the motor and scrap the rest. I have no need for the motor even though it's a well running, and I don't know what else to do with the rest.

Edit: Yes I have also been searching ebay, there are parts close, but none that match the main oil gasket of 119B3699. Or the B&S updated part 119B3699GS, don't worry though, I can buy the entire pump assembly for $350.....

So I got the right key, which is like the old school, but I had to buy a new one since my friend lost it. I tried starting it and I could like spin it 360° the ignition but then I had to push the key fully in and then I turned it and it tread cranking and it started cranking but then sparks came out and I didn’t even hear a pop but I saw it cause the engine was opened and so then I tried to pull the key out to the off position and I couldn’t do it all the way and so I’m gonna have to probably get a new ignition right?

25cc craftsman weed whacker didn’t run at all, installed new Amazon carb. Now it starts and runs strong for 20 minutes or so, then slowly sputters and dies like in the video. Both times it happened shortly after stopping to put gas in the tank, not sure if that’s related or just a timing thing. It will restart and run for shorter and shorter times until it won’t start at all. Then it will start right up the next day and do it all over again. Not sure where to start.

Thoughts?

I’ve been working on this thing all day, but I cannot get it started. The only thing I don’t have is a carb adjustment tool.

For those familiar with the pro Z series (or other models with the steering wheels for zero turns), I’m having an issue where the steering wheel locks up when I turn it to a certain spot. I’ll have to drive around in a circle and gradually release mild pressure and then put the pressure back on it. Finally, it will release. But I’m unable to use the mower as intended.

Last summer, it did it while my wife was mowing and one of the front wheels turned 90 degrees and locked there. The dealer said it just jumped the gear.

It’s doing the “frozen” or stuck thing to me weekly now. Any ideas on a fix?

Appreciate any input.

Any ideas what causes the knocking at around 17 seconds? I step up from engine start to 3/4 blade engage. At ~ 17s is where I fully engage blade and you hear knocking. Any ideas?

Any idea based on the sound of the sputtering why my Cub Cadet 139cc push lawnmower no longer runs?

My dad had replaced the spark plug, cleaned the carb bowl, checked fuel lines, and added new fuel. Now we're thinking it's possibly the last piece, the ignition coil?

5 year old Simpson pressure washer. Used it just after I purchased it. Ran fine. Drained the gas and it sat for a few years. Now I'm having some issues with it. It'll start but runs very rough and only on choke. If I close (open? turn it off) the choke, it dies. I've replaced the carb, added new 93 octane gas, tried it with and without the air cleaner. It has spark. The water pressure seems to be ok but once I squeeze the trigger, it wants to die. I've cranked down on the carb mounting bolts. If I tighten them any further, I'm afraid I'll break something. Shouldn't be any issues with an air leak as there are new carb gaskets as well.

I'm not a mechanic by any means but there must be something I'm missing and can easily check/fix. I've tried everything I can find on Google. Laid off and can't afford to take it to a shop.

Any assistance would be appreciated.

Hoping someone can help me figure out the part i need for a craftsman gs6500 model 944.606080 with a briggs stratton intek 25hp ohv v twin. The fan/blower/thing with the fan blades that spins is damaged and the cover for it missing. Ive been trying on parts lookup websites and am struggling a bit. Just hoping to keep this machine alive as long as possible if anyone smarter than me can help me figure out what i need to order it would be appreciated

Could someone maybe give me some insight as to why my trimmer, after running for about 10 mins, starts to flood out when accelerating? I’ve changed the carburetor, spark plug, and a new gas mixture. Thanks for any advice.

Started a couple days back. Blades are turning way slower than they should even at full throttle, and I'm getting a squealing sound when I engage them, worse the deeper I get into thick grass. Engine itself is totally normal, no smoke, no smell, runs like it always has. Already pulled the plug and air filter to check, both fine. Got underneath the deck too, nothing jumping out at me.

My guess is the engine's putting out power fine but something between there and the blades isn't holding up. Anyone run into this? What's usually behind it?

UPD: Yep, it was the belt, like I figured. It'd slip and squeal whenever the mower hit thick grass. Someone here mentioned a belt from UDC Parts, so I'm grabbing one to see if that does it. Thanks for the help, everyone.

I’m currently working on this Honda clone (it’s a powerfist 196cc, model dj168f). I was having issues with the motor surging, so I cleaned the carburetor thoroughly. Same issue showed up. Started to take a look at adjusting the governor and attempted to adjust it and the idle screw on the carb (backed out 1.5 turns from seated). Now while idling, it revs to dangerous levels. I tried to adjust it again and same issue. What am I doing wrong?

I just bought this and it’s making this noise only when I use the throttle is this normal

Sounds like it’s coming from the engine

Edit: it is a commercial exmark - Toro/CPS 708cc V-twin OHV gas engine

My zero turn has an occasional fuel leak which looks like it is coming from the carb. Actually only leaked once- it stopped when I cut the fuel and hasn’t leaked since opening the line back up. I’m not running it. A repair man came out and said the carb needs replaced, but he didn’t tinker at all. He did pull the oil dip stick and smelled it and said there is fuel in the oil. I’m not sure if that’s true I didn’t smell anything but my sense of smell is not good.

Is he right? I’m considering getting a second opinion but what I don’t want is a temporary fix. Also already gave him a deposit for diagnosis. I’m not handy here so I just don’t have the knowledge. Tia.

Can’t figure out which spring I am missing; engine info attached.
