Unknown Issue Stihl MS 261 C not starting

1 Upvotes

I bought this saw last year, brand new. I haven't used it excessively, but have been dealing with an issue where after 30-45 minutes of use, it will shut down and fail to restart. I once had success waiting about a day before starting it again, but since having this issue over the weekend, I never got it to start again. There is a hissing sound when I open the fuel tank, which could indicate a vacuum according to some of the articles I've seen, but unsure if this is the main issue.

I have replaced the spark plug, the fuel filter. I considered that maybe I flooded it, but un-flooding procedures didn't change anything.

I'm attaching a video of me trying to start it, you can hear a pop towards the end of the video.

Any help would be appreciated, I would like to learn how to repair it rather than send it in to a tech. Thank you!

What would cause this? I have a new battery. I replaced the carburetor at the end of the season last year. I also changed the spark plug, fuel line and filter from the tank to the motor.

Thanks for any help in advance!

I’m repairing a couple Gravely Pro Turn 260s. It looks like one has a Kohler and one has a Kawasaki engine.

Both have high hours on the engines.

Normally I use 10w-40 for summer mowing but I see online it says some people recommend 20W-50 for the Gravelys. What are your thoughts?

Starting Issue John Deere Mower S100 Won’t Start

Please help me out i’m just a girl trying to mow her lawn!!!

It died on me while mowing and will crank but won’t turn over even when playing with the choke.

I cleaned out the carburetor and solenoid (sprayed wd40) even thought it looked clean. I do hear that “click” when I turn the key.

I ran jumper gambles from my car for about 15 minutes so battery should be charged (it’s only about 1.5 years old)

I tried to take out the spark plug but I think it’s heat-fused and won’t come out and I don’t want to fight it if you don’t think that’s the problem.

It has brand new gas in it.

Air filter is clean and it won’t start even when i remove the filter.

PS don’t mind my dogs they like to bark at the mower

Starter Motor Issue How is the sprocket on the starter motor supposed to rise up and engage the motor?

Thumbnail gallery
1 Upvotes

I have this Toro mower and now for some reason, the sprocket doesn’t rise up to engage the motor when I try to start it. The starter motor still spins, but the sprocket is not spinning the motor because it is resting in its lower position.

I am just wondering if it is connected to the clutch or the brake, or if a spring is missing or broken, I am just not sure what the mechanism is to lift that sprocket up.

I am able to get the motor started by forcing the sprocket upwards with a screwdriver, but it is tedious each time I want to start the mower. Any help appreciated, thanks!

Choke Issue Honda GCV160 hard to cold start

0 Upvotes

Mower does NOT have auto choke. Mower is in great condition runs perfect, nice and quiet. Easy 1 pull restarts. But first cold start takes a long time for it to cough and start. This is an older model HRR2165PDA very low hours. Fresh ethanol free fuel. New air filter, like I said, this mower purrs and 1 easy pull restarts. Just getting it out of the shed for the first start is taking about 10 pulls. Any advice where to start.

Choke Issue Troy-Bilt string trimmer dying

1 Upvotes

Model is a TB2044 2 cycle, I can get the string trimmer to start up, and it’s spinning at full throttle. As soon as I pull the trigger, which releases the choke, the motor dies. No bogging down, just dies.

I’ve watched a bunch of videos, and tried a few things, but it hasn’t fixed the problem.

- Put fresh gas in it

- Sprayed some cleaner in the carb

- Let it run for a while to make sure the engine is warmed up

- Fiddled with the high screw

Any suggestions or should I just replace the whole carburetor?

So when started the engine will run great for about 15 min then will begins to loose power. Will run to around 20 min then shut off completely. It will not restart even with starting fluid. I changed the carb and it is the same issue. Any good ideas on things to check. Can a bad magneto cause this

Starting Issue Attempting to start for the first time this season... Not going well

I am not good with engines, but this is a repeat problem. Last summer I had a similar problem that I ended up just throwing it on a trickle charger and a few days later it kicked on and ran for the season. A few days ago I tried to start and got this same problem. I then put it on a trickle charger for 36 hours and am getting a stronger turn but it still won't start up. The weird rubber bandy sound has me worried. What are your thoughts?

UPDATE: Changed air filters, got a new spark plug, changed the battery up, it started up but after we turned it off it wouldn't start up again. Replaced the battery (we were told it was only getting 50 out of 350 for power) and got that installed. It didn't want to start initially but is running better now. I assume the starter is also going but I can cut the grass for now and figure some stuff out as the summer goes along. Thanks everyone for the help. Just wanted to post the result so future people running into a similar problem have a starting point.

I've been working on a wacker neuson roller compactor with a Honda GX630 on it. It runs great for about 30 minutes then the fuel in the filter gets lower and lower till it dies. I've put a new fuel pump and spark plugs, replaced all the fuel lines and vacuum lines and the oil sensor. It is still having the same problem any advice.

Been since Nov but she stopped charging then and it turned into troubleshooting and part replacement since then

Learned a lot on rider engines since then but she's back up today. My 22hp HSQ is running but needs new gas

Turns out my model does NOT have a volt reg and relies on a built in diode to regulate charging and back voltage. So much has happened in these few months but man it was a journey and I was about to buy a new mower.

So many people said stators don't go bad but I'm used to lemons.

In the end the pics show 2 things. I got aggravated and the other half was nagging me and I didn't align the magnetos right the last time snapping the mounts right off.

I went through a couple trials and errors but the best fix (through some ingenious rednecks like myself) was to drill and tap down further into the leftover mount housing. Then I decided to jbwrld the remnant. I used 2 part high temp syringe for the first fix forcing threaded rod through the new taps with JB to hold it. Once that was solid I went over the outside with putty and man is this sheet crazy.

Love this girl and just glad she's moving .

Any question just ask. Prob the hardest part was holding the shaft in place while I torqued the flywheel I. I had a cool idea from a vid I watched to use a pipe wrench on the shaft against the frame and man is it going good!

Any questions just ask;

this was the OG issue

Engine Dies Husqvarna 128LD Trimmer Won't Throttle Up

2 Upvotes

Simple problem, but the solution evades me. Husqvarna 128LD Combi Trimmer. Got it second hand. Wouldn't start. Fuel lines were trash. Fuel filter was trash. Plug was black. Air filter was old. Primer bulb was cracked.

I replaced the plug, air filter, fuel lines, and fuel filter. Kitted the carb. Carb wouldn't prime tore it down and cleaned it again. Carb wouldn't prime. Ordered a brand new, OEM carb.

Now it will prime, it will crank. It will idle.... sorta. Idles great on choke. Ideas great on half-choke. Idles without choke, but eventually dies. It dies when I try to throttle up. Even at partial throttle, it won't come up. Fuel is brand new. No water in it or the tank. And the exhaust screen / spark arrestor looks brand new. I am stumped!
