If u use a 6 point socket u will almost never round out a bolt

We have a brand new Chinese skid steer with likely the same electrical design as your excavator. The battery is fully charged. When we turn the key, the power drops; the lights go out, and it just will not crank, although it is trying to. Do you recommend any steps to check for troubleshooting?

Where are you located? Could you work on my bike?

@86Service - I’m diagnosing a starting issue with my mini after a few of the wires burned in two from being to close/touching the engine. The wires come from the starter solenoid. I spliced them back together. Now the machine will turn over and over but won’t fire up. Any idea what is wrong? I found two fuses and both of those are intact. Thanks!

FYI- The Handle on one of the shock adjusting tool fits the oil plug perfectly. I use a pair of pliers to turn it.

Love vthis video . Ive learned a lot . when checking for 12 volts on the orange wires at the key switch i only get 5.5 volts . I do get 12 volts on the ref wires at the black box but only 5 volts from one of the orange wires out of the black box to the key switch. This tells me that the black box is bad . Would i be correct on this?

Yep fuel pump just like I thought it was going to be, lot’s people might not realize just because the fuel pump is making a sound don’t mean it’s pumping at full pressure, nice job 👍🏽

I have a 05 Suzuki boulevard c50t it cranks idle and you can ride it but it won’t get over 60 and you have to down shift just go up a hill, so I know it need’s a new fuel pump because it sounds like crap, that very well could be your problem especially if it is fuel injected, great vid so far gives me a little more insight on my Kawasaki Vulcan 1600 which is my main bike 👍🏽👍🏽

How does the circuitry work to stop the engine? What's being grounded to stop spark (to kill the engine... if that's indeed what kills the engine)?? Thanks.

Thanks, my mini excavator does similar when i got it, it will only crank with choke pulled but can push choke in immediately and it runs ok at idle and higher RPM with no load, but engine stalls when i start using the hydraulic boom like its not getting fuel or enough, seems under load it struggles, no load it runs at all rpms, but even once warmed up, it wont crank without choke, so I think I need to take carb off and clean it as it isnt getting enough fuel under load

At 17:38 you mentioned you’re looking for metal, but don’t you recall they swapped out the original cover plate it probably came from the previous cover plate.

Thanks a million for the great video! I have a question, I have blown two fuses then it shuts everything down, I believe it has something to do with the light on the bucket, that runs to the switch that you pointed out on your video, my question where could the short possible be? In the light? In the switch? What can I do to solve this problem? Thanks

Great info.

Great video

Where do the vent lines on top of the carb go? Do they connect? Then where do they go?

Great video, wish I found it before I traced half of the wiring myself 2 weeks ago because of a blown fuse. You were testing alternator wires' output to the ground and getting 8.5VAC on each leg. Bet you a quarter they're opposite in phase, centered around ground and will give you leg-to-leg 17VAC.

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.
