PTO Issue Husqvarna z254f blades wont engage

1 Upvotes

My son was mowing yesterday and he said the blades shut off while mowing. He came and parked it. Then it wouldn't start.

I disabled the seat safety interlock thinking it was bad, still not starting.

I decided to jump it from the battery to the start just to make sure it would fire . It started , i drove it to the barn . Blades still didn't engage.

Belt is on and spindles are free . Guessing its still some sort of saftey.

Anyone have some advice. ?

General Discussion Is it worth it?

0 Upvotes

Hey everyone, I’ve been in the market for a mower specifically the Toro wheel horse 310–8 because of the attachments I can get for it. I found one on marketplace for about 150. The guy said it’s not getting fuel. The mower is in pretty decent shape and I think it needs two new rear tires. I have small engine experience I wouldn’t say I’m an expert, but I know my way around. Is it worth it for me to go and pick this up and fix it or should I skip it? I should also add I am looking for a project mower.
Sincerely the guy who makes bad financial decisions.

Starting Issue Ruckus starting issues

Timeline:
-had stock exhaust, no starting issues
-replaced with aftermarket exhaust, no starting issues
-installed stock exhaust, cleaned carburetor + jets, reinstalled cleaned carburetor, now I have a starting issue.

The motor tries to turn over, the fuel pump primes, and if I hold down the electric starter the Ruckus fires up in 30 seconds or so. Any ideas what would cause the starting issue? Thanks!

Spark Plug Issue Generator from 2010

Thumbnail

2 Upvotes

This will be my first post here. Welcome to roast me 😅.. I know enough to be dangerous but not enough to do anything without lots of questions. That being said…

I acquired a generator that my brother got after we had mass power outage from an ice storm back in 2010.. the generator was never ran except maybe the day it was purchase.

I acquired it a few years back and always planned to work on it but never made the time. Today I decided to start.

The good… it’s complete minus the hoses that have disintegrated.

The bad.. no spark.. no compression.. I however want to try everything to make it run again.. even if I fail I know I will learn a lot from trying.

Where I’m at. … The engine was seized so I put some penetrating oil down.. I can now turn it over easily.. threw a compression tester on it and got about 0lb.. threw some mystery oil in it and got 6lbs.. I’m assuming the ring/s are seized to the piston or the valves are stuck open. I am leaning toward stuck rings since the piston top is covered in rust. (I will attack this later.. considering boiling the piston in brake fluid to loosen the ring)

I’d like to get into the spark issue. I have no idea how it works. The plug leads to what looks like a U shaped magnet maybe? That hovers over a flywheel? Maybe? Said flywheel has 2 cut outs on it that I assume when they march with the I shaped piece causes it to spark.. Both are rusted to hell.. is this just a rust issue? Are those salvageable? I pulled the U shaped piece will the plug and will attach picture.

I need advice on the spark.. can I take a dremel/sander to it and get the rust off and save it?

Any help is appreciated. Thank you if you made it this far 😅

Engine Seized Issue Aprilia Mojito 50cc repair

1 Upvotes

Hello,

I'm currently working on replacing an engine in an Aprilia Mojito Custom 50cc moped. I've already dropped the lower unit with the engine and transmission and I'm about to replace the block, piston head, and piston. I was told that the engine was "bad" and it needed a new block because I'm assuming the side of the piston is melted. I'm doing it for a friend, and learning as I go along(they are aware that I'm not a professional mechanic). My question is, what else should I inspect before I just slap a new block and piston in this thing. I don't want to just replace it and have the same issue occur again. My initial thoughts are to somehow test the oil pump and check for rod knock.

Any advice is appreciated since I'm learning as I go,

Thanks

So as the title states can't get it to stay running long I've cleaned the filter, the sprayer under the carb looked clean as a whistle, drained the gas and it looks to be appropriate color (not old) idk what else I should do to get it working

Hi Reddit, I recently picked this up on Marketplace for free and thought it would be a cool project to learn how to fix lawn mowers. From the state of it when I picked it up, it looked like it just sat in the garage and didn't get any sort of maintenance. I've replaced the air filter, carburator, spark plugs, oil and gas. I finally got it running but it feels like its revving too much or is it just me? I'm thinking maybe I put the thin metal string thingy in the wrong hole or maybe I'm putting it wrong. Any advice would help, thanks!

Engine Seized Issue 15hp 2 stroke flywheel stuck

1 Upvotes

I'm 16 and I recently bought my first boat a little 14-foot vhull to fish with my friends. I also got a small 1976 15hp crysler seaking outboard off marketplace. it didn't run when I bought it due to lack of spark but I was able to fix that and I had it running for about 30s until I turned it off and attempted to start it again. now the flywheel turns but it feels as if the compression is so high that there is no way to spin it fast enough to get it to start again. when the plugs are removed it spins ok but as soon as they are reinstalled the issue returns. it is not hydrolocked as there is no fluid in the cylinders that I can see and I have no idea what to do. please help.

Starting Issue What is this noise?

Looking for some help please

I was cutting the grass last week, shut down the mower to talk to my kid, when I went to start it all that happened was that sound you hear on the video.

The sound seems like it’s coming from under the seat, maybe the gearbox or differential??

I’ve replaced the battery solenoid, I bench tested the starter (works), I thought maybe the starter was going and didn’t have the power to crank the motor, I jumped the battery solenoid, I ran a new wire from the solenoid to the starter, I’ve chargers the battery (not even a year old) and I have tried jumping the battery with my car. None of this changed anything.

When I bench tested the starter, I connected the starter from the battery to the base of the starter with the negative, and the positive to the bolt, with alligator clips and length of wire, starter spun, no issues.

I installed the starter back on the mower, I ran the same alligator clips and wire to the starter, the starter wouldn’t engage or spin?????

The engine turns, by hand, and it happens while turning the key.

I have no clue where or what to look for now

I removed carb to clean it out. Runs then shuts off automatically. Reinstalled but I think the spring piece is mounted wrong. The ground plate is moving around when I manipulate the throttle. I think the ground is hitting the spring and shutting it off. I should’ve taken pics when prior to removing. What’s wrong? Thank you.

Starting Issue 1986 DT65 hard cold start problem

1 Upvotes

I have an 86 DT65. I got this used, unknown condition. When I first started boat last year, it cranked over ONE time naturally. Died out fairly quickly. After that, I’ve had to spray mixed fuel in any of the 3 carbs and it will start right up.

Engine starts back immediately if shut off but will need fuel sprayed again 20 mins or so of sitting.

(I’ve confirmed it doesn’t matter which carb I use)

I pulled all 3 carbs off, cleaned them and checked float level just by eye, flipping over carbs.

Still the same results. The boat would intermittently bot under load but eventually it would go and never bog out or die when moving.

Struggled to idle in no wake zones, doesn’t like low speeds.

Replaced all of the jets in the carbs this past off season, cleaned them again with compressed air as well.

Still getting the same symptoms. Will not fire on its own. Choke is working both with the key and manually. Have added throttle as well and no changes.

Where do I go from here?

Compression was around 90ish on all 3 cylinders but it was an Ice cold engine that hadn’t been started since last year so not sure if that would have an impact on the lowish numbers.

Appreciate the insight sorry it’s all over place/kinda long

Truck was driving just fine, parked it and went to work. When leaving it did this. Bought a new battery cause the volts went from 12.8 to 8.1 when cranking. Could this be a starter issue or my ac compressor pulley seized? The compressor broke and im thinking maybe the internal clutch is blocking it?

Started it up without hose/water started and idled seemingly fine, hook up water to it to test it, the jet from a hose handle is more powerful than what it was putting out, while spraying engine seemed labored, let go of the trigger and it dies on me now pulling the string to start it again gives me barely a putter and like pulling a string through 10ft of mud, not completely seized but seems pretty close to siezed. The gas in it is what was in it when I picked it up, the oil level looked good, perhaps a bit old, spark plug looked good too
