My chinese mini ex runs but will suddenly stop running. It will start back up after several attempts and run a bit then suddenly stop running. I thought it ran out of gas but the tank is full. Where do you recommend I start diagnosing?

Hi I’m trying to replace my starter but I can’t figure out how to kill the engine

You mentioned a clean carb. That's what happened to me the carb let fuel fill the cylinder when tried.to start.it .it clicked .Just mentioned it because a common problem with these units .thanks for a well explained non starting issue 👍

To drain the oil, Fumoto or Drainzit with 3/8” hose.

Another awesome video!!

Love your attitude! I'm with ya all the way!! Thanks again for taking the time for this repair.

Awesome video! Thanks for showing us how to fix the carb.

hi i got a question for you. where can i buy the same flywheel ? i need help buying one. can you place a link please. thanks great videos.

I just took this project on as well. Had spark this morning when pulling cord. Lost spark when I hooked up battery. Followed your steps and it worked for me as well so thanks. What did you do for a kill once you unplugged yours? Also any chance you could send me a picture of all the fuel lines. The previous owner had all gas lines removed from tank and fuel pump.

Your 3 videos walked me through and I had the same issue. Followed your video and it worked great for a week and then began leaking again. I think it may be the seal on the interior side because it was paper like material and hardened. I pulled it off today. Do you have any recommendations on which seal to get? I have a vicsec13 and the carburetor was exactly the same. I’d also like to get a second carburetor as a back up, but I am not sure what type this is specifically.. I’m a novice at this and I’m not sure what make and model to purchase. Thanks in advance

No spark on my Chinese excavator. It was running fine, has about 4 hours on it, and it stalled and I’m getting no spark. Please help me diagnose it

Do you know if there is a fuse, we went to start ours and we have nothing, no power, also all the switches for the fan, light and windshield wiper don't work

Nicd job

Outside of the gas caramelization would a quality in line filter be another preventative measure to assist? Install as soon you acquire and/or during cleaning. Good content.

Thank you for posting. I bought one new and I revently had issues with the engine. With less than 20 hours on it, it decided to die. Wouldn't run under load and eventually wouldn't run at all.

A very expensive electrical meter that doesn't work is worth nothing lol I have one also just hate to throw it away because of how much I paid for it

Do you know how to change out the starter

Bought my first Mini Excavator.at a auction (wanted something smaller to do slab work on my place then my 580C) It was sold as DOA. had gas in the crank. Pick it up for just $1000 +18% auction fee and tax. And yes there was fuel in the crank. Shot out about 2" when I pulled the oil cap Drain the crankcase. added oil and Marvin Mystery Oil. Pulled the spark plug and crank it for a min every 10 min. or so for about 20 times Drained the mix and added oil. Checked the float on the carb and found a bit of trash in the bowl. Clean the Carb, added oil. and it started right up. I added a fuel cut off valve where it is easy to get to (below the seat outside between the operators legs) Moved my throttle cable over where I have more moment on the throttle leaver from idle to full power (about 2/3 of the controller) Added a small fan with a attic fan switch in the engine room as to cut the fan on and off (on about 115, off about 95). Fan is wired to a relay through the Acc side of the key switch. Add a Hydraulic oil cooler with a thermostat (controlling the fan) mounted in the drain plug of the tank (used a cooled setting T-stat for it is at the bottom of the tank). oil cooler is wired as the cooling fan Remember you only have 9 amps (or 108 watts) of charging to work with at the most.

Thanks for the vid, I have taken one of these on as a project that was mostly disassembled so it was very helpful to see yours.

What size of battery is in it? CCA?

What makes you all believe that Q12, FF12, mine QH13R have Briggs engines? I replaced the engine on my Little Beaver hole digger fitted with crappy B&S engine with HFT sold Predator. No difference among the dozen engines, most original Honda and Robin Subary I am maintaining for my business. It is most likely Honda knock off, and a good one. So you have a sticker and fancy engraved fuel cap, I don't, but I am thankful anyways.

Nice video, the audio could be a lot better but with the closed caption on I could understand. Thank you and I am interested in seeing one on the carb.

How about a picture of the wiring diagram for the ignition system

I recently experienced an ignition switch failure.....not waterproof.... i attempted to wire in a generic switch but with no luck. I found a stock replacement online but failed to take a picture of the harness plug wire orientation. Could you possibly show a picture of how the wires insert in the harness plug? Mine has 2 yellows together, 2 yellows w/ white stripe together, a white, a green w/stripe, and a black. Just a picture as its plugged in would work....Thanks in advance and thanks for the helpful videos...

Quick question, if this thing breaks down and I need to get it to my garage can it be winched back on to a trailer? Like will the tracks allow it to roll?

Thank you!I have gas running lnto my oil.so this is very helpf👍

I have a brand new mini excavator and the ignition switch locked up to where I could not turn the key so they sent me a brand new ignition switch which I put in but now it turns over but it will not start so they sent me another ignition switch which was just a nap a universal switch with a hand Ron terrible wiring diagram. It’s still turns over but there is absolutely no spark else works. I wondered if you had any insight on this.

I will by the mini skid steer and will probably just cover most part painted with gravel guard ... no more rust gettin to the metal then ...

thanks for making this. Very helpful. Would like to see video for fan install.

The machine is very good to use, mainly because of the low price. I got machine and friend in China.

All done cleaning my carb. My linkage was a little different than yours, mine already had the cable going through the hole in the throttle and two separate cable stops before the hole and after the hole. Anyway my machine is running fine now.

I am going to use that exact oil too. And it is only $12.99

Good job. China sure makes junk lol

Thanks, I will be doing this to mine.

Thanks for this video, my Chinese excavator has the exact same problem. I pulled the bowl and it was filled with gas with junk in it and particles at the bottom of the bowl. I didn't know how to take the carb off, now I think I know :-) There was some junk in the gas tank, I syphoned the gas out and used the hose as a vacuum to get rid of it. Did you get your machine running good?

Did you say you would show how to adjust the valves? I’m interested in getting this machine

I daily to work a 1993 Ford ranger with 507,000+ miles 2.3l 5sp 2wd, but the best part it's still rocking the original engine transmission and rear end! Amazing

Man just wanted to say thanks for posting. Straight forward and saved me much time. Do a DIY hydraulic thumb mod would be awesome.

Do these mini’s go into free wheel down hill ?

So what turns the engine off electrically? The key switch or the big electrical disconnect? And why. Thanks for your time Chad.

Cant thank you enough for making this video! Its so hard to find info on these mini ex's!

Very helpful video. Do you know the maximum wattage these stators produce? I thought it was 10 amp which would be 120 watts from my very poor (not confident) estimates but if you're running 2 - 80 watt fans with no issue it must be higher then that. Thanks.

Thanks for the video.!!!!

very helpful, and easy to understand

Maybe you covered it and I missed it but check swing motor bolts. When I got my machine, i could rock the front boom while looking at motor and it would rock. Loose bolts and need loctite. Thanks, great video!

That little screw plug cover on the carb is probably the only reason for the epa sticker on them. Before import, they have to meet stupid regulations. They can't have an engine running rich or even correctly. Every one is set a good bit lean. Thanks EPA! Funny.

I really wanna buy one of these haha

Thanks for the video. Bought mine with a Kubota d902. I am in it for the ling haul. Yes mine is Chinese, I expected exactly what I got. No surprises. Cheap made, but I like to fix things up. So no complaints from me, would buy again if needed be. The salesperson and I still communicate from time to time. She is not , hurry buy from me, then do not know me. The exact opposite. Very helpful salesperson. Good luck in future endeavors. If one day you upgrade the engine, go with Vanguard in BS line. That is a Cadillac of an engine,everything is of great quality.

If your batching about it why did you buy i

Thank you for the video cause I thought bout buying one of these excavators
