So basically this morning I went to go start the mower and it wouldn't start but then I saw I put the jump pack on top of the engine so I took it off and then it would crack really fast and then it almost started but then I think gas or oil started leaking out of the exhaust I don't know anything about engines or maintenance on a mower and if dont know what to do

I use this trimmer for my business and it won’t run at full throttle, I put a different oem carb from another model that needs a clutch. Still does the same thing. I’ve tuned it, replaced the tank vent, all the lines are good. Doesn’t change how it runs when I put half choke on and open the fuel cap
No idea what’s wrong with it any help is appreciated

I’m replacing the fuel tank on a 6500w Coleman generator and I got one of the universal 7 gallon tanks on Amazon. Obviously these are never truly universal and this one is no different. I need to raise it a little for clearance and also drill new holes in the frame. I wanted to use these double male isolators but the tank holes aren’t quite wide enough and I don’t want to drill holes that close to the edge . I’m envisioning some kind of z shaped isolators or something with some offset. Any ideas? I suppose a Z shaped bracket might work as well but I’m trying to avoid needing so many nuts and bolts

49.7cc air cooled 2 stroke engine. I took a couple videos to better show what’s going on. A couple years this exact same thing happened and we took the carb off, cleaned it out, the jets were clogged, and it ran fine for a long while. Recently the same issue happened and we saw the jets in the carb were clogged again, cleared them and it ran for only one day. We did this again and it once again only lasted a day. We tried to troubleshoot it and we replaced fuel filters and even popped the tank off and completely cleaned that given there was some sediment in the bottom. The spark plug was also recently replaced. We put fresh fuel in and it worked for one day again but then back to what you see in the video. Every time it works for one day, it runs very strong for that short period of time. I don’t know too much about diagnosing small engines, so any advice on what to trouble shoot next would be appreciated.

We changed the spark plug and filter yesterday, but it still sounded weird and not much power. Any idea what I can try next? Thank you 🙏

Can Anyone Identify This Old Cub Cadet Tractor? If you can please let me know thanks.

I recently obtained this cub cadet RZT-L 52” 0-turn for free! I replaced spark plugs, carburetor, air filter and oil change with a kit from tractor supply. As well as new gas/filter. I have finally got the engine to start… but only starts with choke and has a sputter or weird idle. I’ve attached a video. I’ve tried adjusting the governor counterclockwise with the throttle engaged. Any advice…?

Bought this generator for $25 and for some reason it seems like it would rather be a hit and miss engine than anything else.

I have tried running it using a carb, no carb, with brake clean, on gas, to all the same result. Tried another ignition coil I had which also didn’t help. Has a healthy amount of compression and I checked the flywheel, no sheared key. I got pissed off enough I pulled the head off and no blown head gasket. The valves also were sealing and didn’t look burnt. It honestly looked brand new with visible cross hatching and minimal carbon buildup. I ended up just throwing it on the curb but damn I almost never get these cursed engines which take a priest to repair but here we are.

Help please Stallion 8ft dual rotary shredder not working properly on one side anyone know what this one parts called?

I took the head off to do a valve job and this fell out as I was removing the head. Any ideas where this goes?

Hello everyone, just picked up this ride on as a project, don’t have much experience with belt and pulley systems, wondering if anyone can help diagnose this as it’s quite frustrating. Images show belt in disengaged position, when I run the engine in this position the belt still has enough tension where it occasionally grabs on the blade pulleys which leads to a loud banging sound, this also happens when the blades are engaged except it goes away at higher rpms. I have noticed the belt sits outside the belt gaurd in the second photo, if I put it inside of it, it will rub right against that. Any other info you need please let me know. Any help would be greatly appreciated!

I forgot to add the plastic piece before I installed my Echo speed feed head. Some weeds got in between the head and the shaft and I was attempting to remove the head to clean them out but now I can’t get it to lock in place to be removed. Any help is appreciated.
