It is not the throttle.. it is the hydro control lever.

Yep Tom.... I think he figured that out finally.

I finally registered just to chime in on this.

I had seemingly the exact same issue with one of my 125s. Run for awhile, bog down, if i stopped and idled down fast enough i could keep it running sort of, for a minute or two.

If i shut her down and tried again in about 5 minutes, same thing started fine mowed about 4 feet, then quit.

It was a problem that started suddenly after hot rodding around the yard.

Turns out, the PO had soldered inside the gas tank somehow and a bb of solder broke loose and partially blocked the fuel line above the sediment bowl. So when you looked at it, it was full, but could flow enough to sustain running.

Yup had the same thing happen to my son's Original. Only it was a bad tank coating job that plugged the tank outlet.

Hey Everyone,

I finally had a chance to work on the Cub. I took apart the fuel tank, cleaned it thoroughly with water from the garden hose and let it fully dry. Prior to tanking the tank off, I drained the fuel and the fuel looked very clean but I did take a look inside the tank with a light and some some sediment. I could not find any filter or screen but did see a tank outlet ( I think it was the tank outlet, looks like a bolt) and took a photo of that. After draining the fuel tank and cleaning it throroughly, I removed the fuel line (I did this a few weeks ago) and the line was clear. I then removed the carb bowl and that look really clean too.

Anyways, after I assembled everthing, the tractor fired up... I let it run for several minutes before moving it.

Unfortunately, after about 3-5 minutes, the tractor began doing the same thing, bogging down... This time it stalled out. I coudn't save it using the choke and only a few times I could save it by moving the lever to Neutral... I actually had to put it in reverse to get it back to the garage.

QUESTION: The gas tank outlet: Should I have removed this and cleaned this? I have not experience with them so I'm not sure how they work. Is there some kind of screen in that tank outlet? What holds the tank outlet to the tank, is that a nut? What's the best way to remove this if you guys recommend me taking this apart/off to clean it.

I'm going to try posting a couple photos and a video of the tractor running/experiencing the problem. (I"m having trouble uploading the video)

Thanks in advance.

I can't tell what your picture is of. But is your gas tank metal or plastic? If it is metal the fitting and tank are threaded and the shutoff valve screws in. That should be obvious and yes you can take the shutoff valve out and clean the screen. If your tank is plastic, the shutoff valve pushes into a rubber bushing. You can take it apart but most likely you will ruin the rubber bushing and then you gotta find a new one. I'd leave that alone.

HOWEVER..... I would suggest that you take a a good look at your gas cap. There is a vent hole in it and if that vent hole becomes clogged with dirt no air can get into the tank and pretty soon you have a vacuum and no gas will flow. Then your engine dies! Try running it with the cap loose and see if it improves.

thanks I'll definitely check out the gas cap But the last I checked everything looked very clean.... but i'm. it too sure where that vent hole is so i'm curious about that. Ill take a picture of the gas cap and post it as well

the gas tank is plastic. I cleaned the tank out with water and when it was fully dried I hooked up an air compressor and with low PSI blew out the fuel line attached to the shut off valve and it was passing through with no problems indicating to me that there was no clog but air and gas are very different so maybe cleaning it again and taking the outlet out and replacing it with a new one is a good idea too.

thanks again

here's a pic of the gas cap.. couldn't see any issues but let me know if you see anything

landscapebygd · #28 08-12-2017, 07:36 PM

OK so being unfamiliar with the tank outlets and after looking at the pictures more closely I do think that there is a screen on that outlet however it's extremely difficult to get in there to remove it I do have some long needle nose pliers that I'm going to try tomorrow to remove the screen. any other tips?

i'll keep you all updated soon.

I think I may have figured it out!!!

I checked the gas cap a while back and everything looked and still looks clean and clear but I think there's something wrong with it..I switched the gas cap with my other mower's gas cap (wright Stander) which was a loose fit (definitely not the right gas cap for the cub's tank) but with that venting easier it did not buck or bog down once in about the 15 minutes I just ran it...I think that might have been the entire issue this whole time

going to test it out tomorrow again and run it longer

keeping my fingers crossed!
