Thanks. Very hepful.
Thanks for watching! Glad to help!
New subscriber here, but I've been working on small engines most of my life, 54 here, and I have some great stories. Resently I had a customer, he has a craftsman 4in1 vac briggs quantum, I go out once a year right around now to get the machine running for him, I show up, and get it running, I would have to do a carb ultrasonic cleaning, drain the gas out of his tank, reassembly, use my new gas, and it would run like new. Well come to find out what the problem was, turns out he had a huge 5 gallon container of gas, but it was 6 year old gas, that he had collected from his push mowers and tractor over the years, and he would put it in the machine, and it wouldn't run, he's yelling at me saying my work is shotty, and come back, and fix it for free, well after the 3rd time, I tell him it's his gas, it's so old, it is no longer any good, to which he says malarkey, the gas is fine, I leave, and it won't start again, after a few days I get in contact with his wife, I tell her to get rid of the gas in the big 5 gallon tank, I explained why, so she does, and fills it up with good fresh gas, I go over for the last time this year, I clean the carb, and drain the tank, this time he pours the fresh gas from his 5 gal container, it starts, and runs perfectly, to which he says, see I told you the gas was fine, you just did something wrong, I look over at his wife, and we share a wink, cause we know the truth. It just goes to show, you have to swallow your pride sometimes to get the customer happy..... LMAO
Haha!! It really is amazing sometimes isn't it!
Yep that’s just good business and they will be back for more repairs and you’ll the winner
@@philliphall5198 exactly.
I fill the tank full so they won’t dump trash into tank
If it comes back I show them the inside of tank
Always!
Thanks!
Thank you
Video was very helpful. Mower is currently running only when choke is on. I see that I can buy a new carburetor, air filter and fuel filter for @ $40. I have ran it without the air filter over it.. opps! I am guessing I have a dirty or clogged area. Replacing everything seems like a good fix, am I right? problem just started happening and I mowed for 35 min .. but I think I should try to remedy the problem. I am not a great small engine guy, but your video shows that its probably in my wheelhouse. Thanks again!
I would do an OEM carburetor for sure but definitely not expensive to take care of the issue
Moisture problems are a lot worse now because of the ethanol in gas because alcohol draws moisture in the fuel worse than the leaded gas and I try to put my gas can in a shaded area where the can doesn't heat up and build pressure then cool off and draw moisture in when pressure goes down when CAC cools down also I noticed that the air filter doesn't have the foam pre filter up top where air is forced into air filter box from flywheel cover which prolongs air filter life
Very true! Pre filters help in some cases but are not necessary in most cases. Thanks for watching!
I was hoping you were going to show how to take the carb apart and clean it. The swivel pin that holds the float on mine is flared so I can't pull it out to clean.
Not on this one...good trick for that is to pull it out without having the flare go through the hole. If both ends are flared many times you can use a dremel and cut off the flared end and push it though then. Don't try to force it or you will break off the tab. That aluminum doesn't have a lot of strength. Thanks for watching!
I am watching your video on a cub cadet 20 hp Kohler that was ultimately a bad fuel issue water. I have the same mower and having a serious issue with running performance. I noticed a very small fuel leak coming from the back side of the carburetor where I couldn't see. Now I noticed when you removed the carb off the mounting studs that the stud on the right side was loose and I was hoping you were going to mention something about that. But you simply just went on your way replacing carb and securing down with no problem. Well that's my problem, I can't get that right side mounting stud to stay put. I can't stabilize it. I can literally push that bolt straight back into motor with no resistance. Was my small fuel leak because of that I am not sure. But where I felt the majority of fuel was on back side of carb, ( motor side) up top high up on carburetor. So I need to find out how to stabilize that right side mounting stud. The gasket on back side of carb looks just fine but maybe I should replace anyway. You mentioned if you are going to replace that gasket that you should replace the gasket on the other side of block. I was told that block, which in a diagram calls it heat deflector shield, is not removeable. Well that's not true becuase I see they sell that kit. How do I remove that block to replace gasket on other side. It looks like that Right side mounting bolt has a hex head that fits into a recessed spot on that block. But that mounting stud is very loose. Please help I cannot afford these issues.
Just remove the bolt to the right of the studs and it will come off. The right side mounting stud is a carriage bolt that locks into the plastic insulator when pulled outward (away from the engine) it is held in place with the gasket that has a sticky back and holds it in place inside the insulator when it is in good shape
@@IndRepair I have ordered that part called carburetor spacer kit and will install thank you very much for your response
NEVER Trust fuel supplied by the customer!!!
We flush the fuel every time if we are doing carb work, tuning up or addressing a running issue
I agree don’t ever use it
My ltx1054 has similar issues. I noticed the fuel pump vaccum hose to the valve cover was cracked and leaking fuel. I took the valve cover off and gas poured out. I replaced the fuel pump and vacuum hose, but im wondering if this could be a faulty carburetor causing it to leak fuel? I havent hooked uo the fuel line yet, scared to get more fuel in the engine
Definitely have a leaky carburetor causing this issue
I was hoping you'd have shown the tube going up into the venturi. I just did one of these engines.
The "original " carb had a 3/16 straight hole going up, i measured with a drill bit. OEM carb was no longer available so i replaced with a high quality chineesium one. Anyway, it it, there was what i call a transfer tube going up, making the hole considerably smaller. Many briggs, honda and tecumseh have the removable transfer tube style that i clean when doing the carburetor. I theorize that someone either removed or broke this one, but since i don't have another oem to compare it to, i was just wondering if that 3/16 was normal or was i right in thinking something was missing? This mower had many issues with loose, missing or broken pieces so nothing surprises me
The emulsion tube is removable in most of these but this one is fixed if I remember correctly. Running bad without some choke after installing I take it?
@IndRepair actually multiple problems, most caused by whoever worked on it before me. This emulsion tube is removable on a majority of engines, and I think either through loss or someone deliberately eliminating it, the hole going up into my carburetor is a straight shot, 3/16 inch hole, measured with a drill bit. Never seen a 18hp engine have such a big hole into the venturi, which leads me to think this emulsion tube is missing. Since the carb is NLA, and kohler didn't suggest an alternative, I bought a chineesium one, and it's now working fine, and it has a very small hole AND emulsion tube going into the venturi area. Not having another original carb to compare to, I was just wondering if that big of a hole was normal for that carb, but I can't believe 3/16 is right. I wish I could send pictures on UA-cam replies
Yeah that is a crazy one! People do silly things, video coming out today shows how someone installed the rocker stud
What is the little plug hanging not attached to carb solenoid on these for ?
I am not sure what you speak of? The one that attaches to the block is the ground and the other is the power wire to the mower
Also have the same situation going on, a ground and an unplugged connector. Is it just + or where does it connect to? No loose wire hanging around
That’s what I think is wrong with mine how much try that thank you
Glad to help! Thanks for watching!
Can you go out and check how many many turns until the jet is completely tight so I can set my jetting to it because somebody messed with mine and I can't get it right
I do not have the mower here anymore unfortunately. The pilot jet will not affect running much, probably have an issue with an air leak or carburetor still has some junk in it. The fuel has been switched out with fresh correct?
It's the jet needle I would set it and it would run for fine awhile and shut off it ended. being the ground wire
Hi. Yesterday I was attempting to start a SV600 engine that had not run for ages. It's at a charitable org and I wanted to see if I could fix it. I did get it started after making sure the fuel lines were clear. However, the fuel leaked out of the carb whether it was running or not. Just kept dripping. Tomorrow I'm taking the carb bowl apart. Do you think it's an electrical problem or maybe the float is stuck? Getting it running can save the charity money. Thanks.
Probably a stuck float or a bad needle valve keeping it from sealing off. The electrical will not cause an issue like this. Let me know if you need any more assistance. Thanks for watching!
@@IndRepair I'll rechedk that.BTW, what does the electrical device on the bottom of the carb bowl do?
It shuts off the fuel supply when the engine is turned off so you don't get backfires
@@IndRepair So if it's not working, fuel will continue to drain out of the fuel tank into the carb. That's what's happening to my Cadet. Keeps draining 'till the fuel tank is empty. Sound right?
I had mine run it run good smooth living drove around started the blame died now I just want to crank crank crank crank doing the same thing won’t start
Go back through the troubleshooting process again and see what you lost to figure it out. If it starts on startingnfluid we know we have an issue with fuel supply. If not, a compression or spark issue is like so check spark next and go from there
Does this mower have a fuel pump?
This one does not but many of this style do have one build in and is easier to access if you take off the top cover
does this use a fuel pump
Not on this model. Sometimes they will have a fuel pump. This will be on models where the tank is in the rear normally. Thanks for watching!
My throttle were the spring connects is hitting heat deflector why
Hard to tell for sure buy many times it is because the deflector is warped or cracked
@@IndRepair it is the fuel line causing it not to go on, ive did this a many times and cannot figure out what is wrong.. i bet i have worked 9 hours trying to get it on i tried rerouting it still will not let me push it on im so confused about it, like I said i have done it many times
Ok, I thought you said the linkage is hitting the deflector?
@@IndRepair it is but was gonna just try and put carburetor back on and try to crank but my fuel line connects to the fuel pump above and I just can’t get the air filter housing back on because of that fuel line going to carburetor
The nut on that stud on the right pulls the stud out of the engine and feels like it is threaded into plastic. Any ideas?
It just sits in the plastic as a carriage bolt and tightens everything against the plastic, it should be losses until putting everything back together. It does n9t actually screw into the block. To remove and inspect remove the bolt to the right of it that holds the plastic insulator on. You probably with need to replace gaskets then also
AllWAYS check and dump fuel first
Yeah, so often the issue!!
Don’t start or run a lawnmower if there’s a gas or oil leak, take it to a mechanic or call
Good tip! Fire starts easily!
Do you by chance know the carb float gasket part number
We use kit 20 521 02-S for carburetors with a fuel pump and 20 521 01-s for carburetors without a fuel pump
That's the wrong type of fuel filter for gravity feed carburetor. No wonder it doesn't run right
Lol, I'm sure the water in the fuel had nothing to do with it
That mower is utterly filthy for being completely service 1.5 months ago...... yikes
Oh boy you would be surprised! Seems like nobody takes good care of their equipment anymore
Wrong lawnmower a n engine
Not sure what you are saying
