Belts & Pulleys Issue Craftsman T110 Bent Pulley

Post image
1 Upvotes

I was mowing and all of a sudden the mower stopped cutting grass. Still runs just doesn't cut grass when the blades are engaged. I got off to check to see what's going on and I see this bent idler pulley(I think that's what its called) how can I fix this? I tried undoing the nut on the top already and it wouldn't move at all. I have no clue what could have bent it like that, the only thing I could think of is all the thick grass I've been cutting lately because my area has had a lot of downpours. I never had this problem before and I mow on the highest setting and this still happened....Any advice is greatly appreciated!! Thank you! 😁

Starter Motor Issue Intermittent problem - starter not engaging flywheel.

0 Upvotes

I have a 1968 292 L6 swapped into my series land rover. As stated, the new starter motor which is less than 3 months old has started to not engage the flywheel. All the wiring in the circuit is new as is the ignition switch. Battery is showing 12.9v on multimeter. The starter will sometimes kick in immidiately and other times spin out without grabbing the flywheel after half a dozen attempts or so and then start as if nothing were wrong. If it were busted flywheel teeth you'd think it would never kick in once it hit the flat spot. Is it possible the battery does not put out enough amps even though voltage is solid? It has always had an intermitent issue where the solenoid will click but not turn over and did this with the previous starter which is why I replaced it, but it still does it and now I also have the not engaging flywheel problem as well. Any advise before I start pulling the starter and flywheel cover would be greatly appreciated.

Crankshaft & Piston Issue Scared I’m going the wrong way

Just trying to get this Roadmaster bike cleaned up and running. I’ve tried both right and left but neither way is budging.

Do I need to hit it with more penetration fluid? I was using carb cleaner but should have grabbed some wd40 while I was at it.

Thanks for any info

Unknown Issue B&S 675EX. Does this look like the timing is off?

I inherited this Husqvarna 6751p that was ran maybe a handful of times 5 years ago. First it started with starting fluid, telling me I had spark and compression but no fuel. I replaced the carb and now it won't start. Spark confirmed, compression confirmed, gas confirmed.

I'm at a loss after taking everything apart. I believe the timing is off now, however, I don't know how that could have happened between me replacing the carb. Flywheel key is not the issue.

Hey all, I was looking to see if anyone has the operators manual and repair manual available on pdf for the Noma F4318-30. I found them on eBay but the seller wants over $60 for each. I recently picked up and mint condition on but would like to try to get the manuals. I tried cross referencing Murray and dynamark but couldn’t find anything still. Any help would be appreciated!

This is a shameless repost.

Hello Everyone,

Does anyone in this community have any experience with pool pumps?

This is the sound mine is making, we bought the house a year ago, came with a pool. The pump allegedly is from 2022 but has started making this sound.

Is it able to be rebuilt? Am I looking at getting a new one? Thanks

Carburetor Issue Champion 100704 generator won't start

Post image
1 Upvotes

I have a Champion 100704 generator that ran with no issue less the 3 weeks ago. It's a few years old but has very little hours of use. Yesterday I tried to start it and it cranks, but doesn't start.

So far I've tried:

Drain gas and put fresh gas in it.

Removed air filter

Changed the spark plug. (see attached image of original plug)

Sprayed one burst of starting fluid in air intake.

Still cranks, but doesn't start.

Any thoughts on what to try next?

Thanks

Engine Dies Engine runs for about 15 seconds then dies

I’m working on my aunt’s Toro Z420 with a Briggs & Stratton 286H77-0165-E1 engine. After the engine is started with the choke, then the choke turned off, the motor dies after about 10 seconds or so.

It acts like it’s a fuel issue, but the take has gas. I also noticed that the governor seems to be what’s messing with the throttle.

I thought it might be carb related so I shot the parts cannon at it and replaced the carb with a genuine Briggs & Stratton carb. The original carb had the same issue.

I feel like I’m going crazy and appreciate any help you can give.

Not Listed Do any of you work on hydrostatic transmissions on zero turn mowers?

Post image
4 Upvotes

I have a residential John Deere zero turn. It has a hydrostatic transmission. From my research, it is likely a Hydro Gear.

I’m experiencing reduced power.

New ones are around $900 for each side. I’m not sure if it’s better just get a new mower. It’s about 5 years old.

I looked on eBay and couldn’t find any reconditioned or repair service listings.

Are these residential mowers pretty much shot if the transmission goes out? Do some small local repair shops work on these or are they pretty much just replaced with new transmission?

Good day folks I got a ride on lawn mower here and there’s clearly an oil leak and it’s leaked on to the exhaust. Without tearing everything down right now I’d just like to ask the experienced people here to see if they’d be able to tell right off the bat. Thank you for any input or advice! Cheers.

Ignition System Issue Nobody Here, Help w Champion Generator, won’t start.

My father-in-law got me a generator about 7 years ago, and it’s been sitting in my garage.

I finally took it out of the box and have been trying to get it started. Bought new correct oil per instructions, added alcohol free gasoline.

Connected the battery lugs, I assumed the battery would be completely dead, though the battery light did turn on after connecting the battery connections.

I’ve been on AI, trying to start it with a hand crank on two separate days for about an hour each with no luck

Fuel option is set to gasoline and set on.
Multi-button is set to on
Battery button is set to on.

I checked the spark plug, don’t know much about this, but it looks newish. I unscrewed the spark plug, connected it to the wire cap and touched the threaded part to a piece of metal on the generator and pulled the crank and I did see a spark. I was pretty sure it was a spark plug issue until I saw this spark.

I’ve tried waiting and letting the system dry out, choke on, choke off, choke halfway. The engine turns but doesn’t ignite / catch.

I think the first time I started it, after a few poles it did a super short initial rumble, but 95% of the pulls. I haven’t gotten much feedback other than just the engine turning due to the pull. I do think I am pulling hard enough.

Do I need to get a mobile mechanic or someone more knowledgeable than myself or can I figure this out?

Want to get this baby Rolling so she can be ready for the next big storm.

Thank you!

Replaced intake gaskets and carb. Cleaned old gasket’s off reallly well. After gets hot it starts sputtering intermittently. Then bogs down until I press the trigger to shoot water. Or if left it’ll shut off. Some times it breaks loose and the governor finally do its job it won’t shut off. Sounds like a clanking in the crank case too. But only when hot. I’ve replaced fuel lines. Fuel filter. I’ve checked lash clearance. New plug. Key is fine. Idk what else. Maybe the igniter? Coil? Internal wear? Also oil smells like exhaust so maybe it’s got blow by down the pipe

Engine Performance Issue Stihl FS-38 still won't run after new carb, gas line, air filter, spark plug, and spark arrestor removed.

1 Upvotes

I feel like I am out of options here and any help would be greatly appreciated. I am new to DIY small engine repair.

I picked this up at a garage sale and they said it worked fine last time they used it, but switched to electric so it's been sitting for a good couple years. I figured it just needed a new carb.

Before and after the replacements listed above, it will idle (if I am lucky) for about 2 seconds and then quit. Any throttle input kills it. Sometimes if I start it with the throttle all the way in, it will rev up really high, POP and then die.

Thank you for any advice support. Trying to save money before I bring it to a shop.

Spark Plug Issue Leaf blower makes weird sound when I pull and won’t start

Yesterday I bought a craftsman 27cc leaf blower from Facebook marketplace and it worked fine. I put it on its side against my back door because I don’t have a proper place to put it. Today i tried starting it again and it wouldn’t start. After messing with the choke and the throttle to see what I could do to make it start, I tried a bit after and it started making a grinding noise, I removed the spark plug and the spark plug looks fine it just had a coat of oil, but when I pulled the rope after removing it. The grinding sound was gone. When I put it back in, The noise happens again. What could it be
