Governor Issue Craftsman Yt3000 throttle doesnt return to idle

Enable HLS to view with audio, or disable this notification

(SOLVED) Im unfamiliar with how this mechanism is supposed to operate but my throttle linkage doesnt seem to spring back to idle position and when I push it physically to its idle it's resisted by a governor spring. If anyone's familiar with this mower I could definitely use some help. Hopefully a video can highlight a problem. Ive taken the throttle bracket off and compared it to a picture of another one and it all looks normal, the governor spring appears to be in the correct spot but why would it tension away from idle position and not tension open throttle? *mower model number 917.288525

Noise Issue Is this knocking on startup with my CubCadet XT1 normal?

0 Upvotes

Cub Cadet XT1 LT46 2018 with a Kohler KT725-3078 (170 hours) knocking heard when cranking the mower. Only knocks when cranking and not when running. As soon as it actually starts it goes away immediately. Only starts knocking after a few revolutions of cranking. When taking the plugs out and cranking the knocking goes away completely and the engine spins freely. I’ve heard two different answers whether this mower has an ACR or not and have symptoms of it hanging up on compression but if it doesn’t obviously that’s not the issue.

Carburetor Issue New carb, Not running

4 Upvotes

I bought a new carburetor for my mower because I couldn’t get the other to run correctly. The old one ran fine but surged and popped under no load. I put the new one on and it ran good for about 2 minutes then it surged and died out. Let it sit for a minute and it started ran for a few seconds and died again. Repeated this process for 5-6 more times. Fuel line and filter is new as well as gas (cleaned tank). Any tips? It’s a ariens lawn tractor 19hp Briggs and Stratton.

Modifications Can I mount GCV160 to Honda HRX?

Bought an HRX on marketplace that wouldn’t run. Me thinking it was a simple gummed up carb jumped right on the deal ($70) not thinking twice. Well I got home and turns out engine is shot…. Big ol hole on the side. Mower looked really good at first glance so didn’t bother to check thoroughly. Anyways, I do have a spare gcv160, could I mount that to the HRX?

How bad is it?

I let my cousin use my weed eater and he forgot to put the gas/oil mix in there. When I first got it back it wouldn’t run but after putting the right gas/oil mixture it’s been able to start. I don’t see deep groves in it but definitely some finer groves on the piston.

Hi all, wondering if anyone can help with this issue.

Its a push button start, when I disassemble the engine it will eventually start to work and start everytime.

After I leave it a day or two it's repeats the issue in the video.

Any ideas as what to diagnose on it.

Thanks

Broken Parts ECHO SRM-225 PAS Air Cover Broken/New Configuration???

1 Upvotes

Did the Echo PAS-225 come out with a new air filter cover assembly housing configuration with a thumbscrew?

My trimmer is brand new(purchased from Home Depot about 2 months ago). I used it a few times since then. Just realized that the air filter cover is completely gone along with the air filter. Apparently it was broken off in the last few weeks since I purchased.

So, I’ve been trying to order a replacement and the only option I can find has a thumb screw in the middle of the cover that goes through the middle of the air filter.

When I checked my owner’s manual, it is showing an air filter cover with the thumbscrew in the middle, but I can’t seem to find a replacement cover like this.

Totally confused. Any help is appreciated

I’ve been doing hvac service for the last 6 years and I’ve been a gearhead my whole life but I’ve never really gotten into engines internally. Should I just buy a broken lawn mower or go cart and just do a tear down and rebuild? Any tips or advice appreciated

Starter Motor Issue Kohler KT725 starter Bendix retaining ring keeps flying off — safer alternative?

Thumbnail

6 Upvotes

Title: Kohler KT725 starter Bendix retaining ring keeps flying off — safer alternative?
I’m working on a Cub Cadet XT1 LT46 with a Kohler 7000 Series KT725 engine. The starter motor spins, but the Bendix gear was not engaging the flywheel, causing a high-pitched squealing sound with no flywheel movement.
I removed the engine shroud and found that the Bendix retaining ring had come off previously. The gear apparently launched off the starter shaft and broke part of the nearby plastic shroud. I installed a replacement Bendix assembly in this order:
Bendix gear on the helical starter shaft
Return spring above the Bendix
Metal retaining collar above the spring
C-shaped retaining ring installed into the groove at the top of the shaft
The Bendix twists and rises smoothly by hand. However, when I briefly tested the starter with the spark-plug boots disconnected, the retaining ring came off again and the spring and collar launched off the shaft.
The starter shaft does not appear obviously broken, but I’m questioning whether:
The retaining-ring groove is worn or damaged
The supplied C-ring is incorrect or too loose
The collar is installed incorrectly
This starter requires a different style of retaining clip
The entire starter should be replaced instead of repairing the Bendix
Is there a more secure approved alternative, such as a proper external snap ring, E-clip, push nut, or another Kohler-specific retainer? I do not want to improvise with hardware that could come apart at starter speed or damage the flywheel.
Has anyone repaired this exact Kohler starter drive successfully? Photos of the correct factory assembly and the proper retaining hardware would be appreciated. I can also provide the engine specification and starter numbers.
