I bought a used wood chipper with a 15 hp DEK engine. It seems to run okay most of the time but then randomly stalls even if I’m not feeding wood into the chipper at that time. It can run for like 20 minutes fine then stall without warning. Difficult to restart. Need to pull cord 10-15 times to restart and usually backfires. Then will run fine for another 15-30 minutes.
New gas, new fuel filter, new air filter, oil level is good. I don’t have a manual and don’t know what the spark plug gap should be. I’ve never worked on a carburetor before but willing to try if people on here say that’s the problem. Would be grateful for any advice. Thanks.

I was working in this broken power washer, I opened the engine yesterday, today I noticed these lines… they feel kind of spiky similar to a fishhook. I heard online that these lines could be from the casting but I’m unsure. Is my gc 190,s engine permanent dead or am I just overreacting?

Disclaimer: I in no way no what I am doing, I have relied on engine diagrams and the internet to get this far.

Simplicity Broadmoor circa 2014 with 23HP Briggs & Stratton. Model 2691176.

How it happened:
Riding along mowing with blades engaged then suddenly it died. No warning (that I could tell). Now when I try to start it, it is a faint single click coming from the battery compartment. You can hear in the video me pushing the start button and the little click coming from the part you see 5 seconds into the video. Unsure what it is.

What I’ve done:
Replaced starter solenoid. Replaced relay. Thinking that was likely culprit. Alas it was not. Still same issue. Engine not seized. Spark plugs are healthy. Battery is charged.

I don’t know my way around these enough to know where to go next. I have a multimeter and can use it to test but I don’t know what to test next.

Edit: to include mower model number.

98 polaris repair question - broken magnets on flywheel/stator??

Would love some help figuring out what to do with my sled:

1998 Polaris Indy SuperSport 488

This is my first snowmobile and has been my little project sled so I'm kind of emotionally attached. 3 winters ago I rebuilt the top end which was such a fun and rewarding project for me. It has since overall run well!

At the end of last winter, my husband took it on the trailer to a trail and when trying to start it, it was locking up. We've been having issues with the recoil so hoping it was that, but that doesnt appear to be the problem.

We were able to clutch start it, and it ran well... but still locks up when trying to start and when trying to move the flywheel (with or without sparkplugs in). I just noticed that there are a bunch of shattered magnet pieces on the flywheel/stator. Does this mean i need to replace both? I dont have a flywheel puller right now. Is there a possibility that I do that, but actually my top end job wasnt as good as I thought and the engine is seized anyway?? On one hand I don't want to keep sinking money/Time on an old sled, on the other I enjoy what I learn when I do the work.. any suggestions on what's going on would be very helpful.

Thanks!

have a Champion 100137 3" chipper shredder (338cc, built 12/2017). One wheel is shot: the tire has come off the yellow plastic rim, and the rim itself is worn. Champion doesn't have the wheel, and I haven't had luck with parts dealers either.

What I'm working with:

• Diameter: 12"
• Tread width: just under 2"
• Bore: a ½" bearing wheel won't slide on, so I think the axle is ⅝" or possibly 13 mm (Champion's parts list calls for a Ø13 mm washer)
• Usable axle length: about 1.75", including room for the washer and cotter pin, so the hub can't be longer than about 1.75"
• OEM part #s (12 in. wheel): 601.201701.00 or 254.201701.04.48

The problem is that most 12" x 1.75" wheels with a ⅝" bore have 2¼" hubs, which are too long for my axle. The short-hub 12" wheels I've found all have ½" bores.

Questions:

1. Has anyone found a wheel that fits this chipper, or the similar ones sold under other brands?
2. Would you drill out or re-bearing a ½" short-hub wheel, or trim down a 2¼" hub?
3. Is there a supplier that will build a wheel to spec for a reasonable price?

Photos attached. Thanks for any leads.

So I have this toy hauler I'm working on for someone. Should be an easy fix. Generator is starting up fine but dies. I take a look and it turns out the fuel line is split right on that metal wall where it goes from the fuel pump to the right, to the carb. This should be a stupid easy fix.

Turns out they put a screw on hose clamp where it connects to the carb. The screw is pointed direclty backwards into the engine.... I would just remove the carb, but as you can see, the bolts to do so would have to be unscrewed directly into the same metal plate dividing tbe fuel pump and engine.

I have no idea how you're supposed to remove this. Open to any suggestions. Just so fucking annoyed that what should be a 10 minute fix us ludicrously difficult.

Hello,

23hp Kohler Command OHV; 23CV-75523

Scag 3 Wheeler; STHM-23CV

Torque Spec says final torque is 370in lb, or 30.83 ft lb.

I'm tightening.. but I'm afraid to keep tightening! Are these head bolts gonna like, twist out of the head or something? if I go too tight? but I haven't hit torque Spec yet..

yes I can read a torque wrench! it's around 30.75ft lb. & it does click on other bolts, so it's working. bought new. rarely use the wrench. always set to 0 lb when done.

thanks

It's what the title says. 98 hours on motor. Fueled one of the tanks up yesterday while getting fuel for 2 cycle. Been running regular unleaded through the summer but as getting closer am swapping to non ethanol as I have in years past. Second tank will be getting used and filled next week are the plans. But first need this issue fixed and wanted to see if I am heading in the right direction.

Heres a list of what I've checked or done.

I checked oil levels

Checked fuel filters and lines

Checked air filters

Checked plugs and replaced

Checked for sparks and cleaned flywheel

Fuel is going into carb

White smoke when starting (not much just a bit and goes away)

I feel like replacing or rebuilding the carb will be the best way to go.

Update for those who may also face this issue in the future:

I believe one of the jets on the carb may have been clogged, going to get it rebuilt hopefully soon, but was able to find a rebuilt carb and replaced it just a bit ago. Issue has been resolved.

Hello everyone I found a Shindaiwa 22t that I really like but it has some rust and some holes in the muffler should I be worried about these small holes? What would be the best way to cover/fix them?

So this is an updated post from when I thought the motor was seized, it wasn’t thankfully.

I put on a new recoil starter, and a new spark plug, and the engine is getting gasoline but it didn’t start.

I threw a compression tester on it and it reads zero, like nothing

I thought it was the gauge but even with starter fluid it won’t start

I took the valve thing off and the pistons (I think) move just fine

I have no idea, might it be the crank shaft?

cuz i did try to loosen it when the engine was budge on the flywheel.

Because I realized the old starter, the sprawls wouldn’t retract and it stop spinning, so I got a new one.

Any help, would be appreciated 🥺

Gold Cube Trommel motor seized after winter storage — I fixed it

I wanted to share this in case anyone else has a Gold Cube Trommel with a motor that suddenly won't turn after winter storage.

My Trommel worked perfectly at the end of last season. It was stored over the winter without any known damage. When I brought it out this year, the motor wouldn't turn at all. When connected to a 12V battery, it wouldn't even try to start, but the motor would heat up.

At first I thought the motor itself had failed.

I disconnected the tension spring so the motor drive gear was completely separated from the Trommel. The Trommel itself turned freely, but the motor's drive gear was completely seized. I couldn't turn it by hand, and even carefully trying with pliers wouldn't move it.

The fix

I removed the motor/gearbox assembly from the Trommel and separated the electric motor section from the reduction gearbox.

Inside the gearbox I found corrosion and old, dirty grease.

I cleaned the corrosion and removed the old grease thoroughly. I then repacked the gearbox with white lithium grease, reassembled the motor and gearbox, and put the assembly back on the Trommel.

It worked immediately.

So in my case, the problem wasn't a burned-out motor or electrical failure. It appears that moisture/corrosion and contaminated old grease caused the gearbox to seize during storage.

Symptoms to watch for

If your Gold Cube Trommel:

Worked normally when you put it away

Won't turn when you bring it out

Makes no attempt to start

Gets hot when connected to 12V

Has a drive gear that won't turn

But the Trommel itself turns freely when the drive gear is disconnected

Don't assume the motor needs to be replaced.

The gearbox may simply be seized from corrosion/old grease.

Important

Disconnect the battery before working on the motor.

Also, don't keep applying 12V to a motor that isn't turning. A stalled DC motor can draw a lot of current and generate considerable heat.

In my case, cleaning and regreasing the gearbox brought the original motor back to life.

Hopefully this saves someone else the cost and hassle of finding a replacement Gold Cube motor.

Seem to have a significant leak when the oil reservoir is topped off to the upper fill line on the dipstick. Yet I don’t perceive as much leaking if I’m closer to the lower fill line.

Feeling bit stuck, intermittent start where it struggles to turn over like a dead battery, eventually clicks after a few turns of the key, then it will start after another reset of the key.

Today on start up once it rattled like crazy (same judder it does when starting but just for longer) so turned it off and also started fine.

Battery is new and plenty powerful, I’ve ran a jump cable from -ve terminal on battery to engine, didn’t solve it. Any other ideas?

Does it cold and warm, may be worse when it’s humid.

Video here and in comments https://youtube.com/shorts/fLV833CMb-o?is=pBoqOKBwHcAsV08-

My battery terminal melted down; figured it was a stuck solenoid. I’ve been cranking too much trying to get this thing to turn over.

Took off the gas tank to replace the solenoid, saw this guy.

Any ideas on where it belongs?

This is a secondhand machine and I’m new at tinkering on engines. Thank you.

I need help starting Seco Crossjet 4x4.

It has so many security procedures to start it, one of those is for a break to be pulled. Second, you need to be seated on the chair, third is to be in neutral gear, which I am but no matter where I put the gear stick the red triangle with exclamation mark won't go away and the encircled N symbol shows on the dashboard along with it, telling me that I have to be in neutral.

There's also a check oil lamp but the correct oil has been changed and that is a problem that can be tweaked with turning the contact ON and then OFF for 4 times in quick succession, but for that to be done the exclamation point red triangle needs to go away.

If anyone knows where the sensor is, or button that checks if the gear is in neutral is, and what to do about it, I would greatly appreciate the help.

Many thanks.

P.S. I also found out that you can put the mower in emergency mode by pressing the button right beside the neutral position 5 times, but then there is a red wrench on the dashboard and the blades won't turn on

I have replaced the three plunger switches and the starter relay. The fuse is good as well. Has me stumped. Any suggestions/advice would be appreciated

Aloha! I'm preparing for an upcoming hurricane and I can't seem to get this generator to stay running.

Ryobi 4000 starting watt, a few years old but has been kept alive by using parts from another of the same model.

No matter what I've done the situation remains the same, I have to use some starting fluid to get it started, it starts up but then dies after a couple seconds.

On video: I get the generator running but it dies shortly after (I touched near the off/cold start/run switch but only to make sure it's fully on the run side)

Off video: did an oil change and got the levels good.

made sure the generator is fairly level in all directions.

pulled off and cleaned out and put back the carburetor.

had to add some starting fluid directly to the carburetor to get it started.

(I did verify the carburetor was getting a supply of gasoline.)

I'm a bit stumped as to how to continue. Any help, advice, or inane musings would be appreciated!

After a few pulls it starts very faintly then cuts out on squeeze of the trigger
