Just a clarification on the engine in this video- these engines are built by a company called LCT- Liquid Combustion Technologies. Many people think they are a China engine- they are not-they are designed and built in the USA but they do contain components made in China- like the Huayi carb you are working on in this video. LCT basically encompassed what was left of Lauson/Tecumseh engine division, but by no means are these engines a Tecumseh. There is a lot of information on the internet about this company and is an interesting read. The main thing is LCT engines are used exclusively by MTD and nobody else. Because of that fact, they are often referred to as MTD engines to keep it simpler. In most cases, you would order parts for these directly from MTD, and most of the parts do in fact use MTD part numbers. I have seen a few of these engines that actually have a LCT sticker or designation on it, but very rarely. Most of the time, the engine will have a sticker for the name of the product, such as Craftsman, Cub Cadet, Yard Machine, etc. The whole thing is kinda confusing and ridiculous, but I wanted you to know the story behind it. I have replaced many of that very carb you are working on out in the field. We don't have any way to clean them ultrasonically (which is the only way to actually clean carbs effectively) so we end up replacing them with new ones. Those little internal "circuits" you pointed out are often where things tend to plug up, and you cannot get to them to clean them unless you ultrasonically clean the carb. Anyway, sorry for the long blurb. Just thought you would find the information helpful and interesting. Great video as always Zippo!!
Thanks Mike!! I've pinned this comment for all to read and I'll certainly brush up on my know how on them. I thought I remembered you saying something akin to the Lauson name a while back. I guess my memory isn't as bad as I thought lol. With the carburetors being less than $20, I can see where just replacing them is the easiest route when on a call. Also...I learn a little slow sometimes. Just removing the carb studs frees up the carb. I actually unbolted the engine and raised it up lol. But, it all worked out! I am glad you chimed in here so that anyone wondering will know. Cheers my Friend! Zip~
I am a little curious about your summation of what all engines need ..."gas, fire, and spark"? (approximately 11:06 in the video) I always thought they needed fuel, spark, combustion, and timing. Lol. That's ok, Mr. Zippo. Whenever I get busy working on something my mind plays tricks on me as well! I loved the video!
Great video Zippo. Bruce the Great Pender has many good ideas and techniques. Both of you are fantastic mechanics and teachers. Thanks for the information from Mike about the LCT company. Keep the video's coming.
There is another way to remove the carb. Possibly the only alternative for folks who don't have the tools to pull the studs. It is pretty easy to remove the plate that the fuel solenoid is bumping up against. Sounds like a big deal but it isn't. 4 screws hold the plate, and as I recall you have to pull a 14mm bolt from below.
@@ZippoVarga You just gotta wonder how hard it would have been to provide the clearance for the solenoid. Marquis de Sade school of engineering, IMHO. BTW, for people interested in other aspects of the engine, like valve gaps and so on, you can find the shop manual by searching for "P90 Series Vertical Shaft Engines". They go in a variety of machines- cub cadets and MTD. You can get an entire replacement carb off of Aliexpress for less than the cost of the solvents to clean one properly, but I am against disposing of perfectly good and easily cleaned carbs.
@@02025 , I don't know of one, but if you look at how the plate attaches to the frame, you just take off those 4 screws and you are good. You need to loosen (no need to remove) a bolt that is underneath the chasis that secures it to a piece of steel that runs the width of the chassis to an identical plate on the other side of the mower. If you put the back of your hand on the steering tie rod and move it just under the chassis, you will feel a 26 or 24 mill bolt. My notes above say 14, but I think it is bigger than that. . Anyway, loosen that puppy and you will be able to move the obstructing plate down or out of the way enough to pull the carb. You can take it off if you like (which is what I did the first go around, but I figured out you really didn't need to remove it or the front screws. If you get it figured it out, maybe video it for the next person who doesn't have the stud tools.
@@SwarmerBees Thank you! But I had more than 4 bolts holding the chassis on so I researched the video and saw the studs were THREADED at both ends. I simply clamped the alligator pliers on the non-threaded part and muscled each one out. Easy! I'll add that there are several carburetors on Amazon that might fit here with an ANGLED fuel solenoid that might have saved this step. Thanks again!
Nice tray JIS screws. I have been shopping for the screw drivers. No suppliers around here sell them, I am going to order them online. I got that you don't rinse after the parts coming out of the cleaner. I should do a carb in the sonic cleaner then take the welch plugs out to see how clean the inside cavity is. Loved it.
I highly recommend the Vessel Impact Drivers if you're going to invest in a set of JIS Drivers Bruce. Or, Vessel has many other JIS options if you don't want to spend that much on drivers. Cheers my Friend! Sean~
Thanks for that video Zippo. I have seen a couple of those carbs in my shop and one of them I had to put a small slot in the end of it with a dremel tool and back it out. Our brilliant EPA made some companies do it. Others had a plastic cap on them and would often bread off the end of the adj. screw so I would also use the dremel to do the same. Thanks for the great video's.
They must have used a specially made threaded tool that ran the idle circuit screw in, then laughed at anyone who encountered them after the fact lol. Tecumseh just pops a plastic cap on them. Which I prefer, since you can still service them. Cheers! Zip~
Today's fuel is laced with Ethanol, which pulls in moisture and destroys carburetors and fuel systems. Chances are good you'll eed to replace your carburetor and clean out your gas tank thoroughly as well as run new Ethanol resistant fuel lines and in the future, either run the fuel tank dry at the end of use or treat with ethanol fuel treatment. Zip~
Even though it was my first MTD engine, the learning curve wasn't too bad. The one thing I did learn is....Take the carburetor studs out to get the carb out instead of unbolting the engine and lifting it. Cheers Danny! Zip~
thanks for the video, I just put a new carb on and my mower runs like new. I did have a bugger of a time getting the bolts out that held the carb on. seems weird they designed it so it dont clear the frame. THANKS
When U first described the choke lnk, it sounded like the Infamous "choke-a-matic" a good example of learning via exploration! One for the library Buddy!
These carburetors are very reasonably priced, but since I had the Ultrasonic cleaner, I cut out that expense and time to wait for it to arrive. Fortunately, it wasn't too gummed up or blocked to bring back. Cheers Mule! Zip~
I’ve had this tractor for 12 years , it’s great . My front yard is kinda big , takes 20 minuets to mow. It’s the fastest I’ve ever had , . I’m am disappointed to find out my lawn tractor is not a tractor 😢
Jim, calling a machine that isn't capable of much more than mowing a tractor is a marketing ploy by Craftsman. That's not saying they aren't good at their jobs. But a Tractor is something that's very capable at a multitude of tasks, like my Simplicity and Allis Chalmers Garden Tractors. They've got over 40 implements and are capable of doing anything the larger farm tractors are on a smaller scale. This is the only reason I stated they're not a tractor in the literal sense. We can call our all wheel drive Honda Pilot a 4 wheel off road vehicle when in reality, it's an "all wheel drive" that just keeps you on the road. Potato Patato, Tomato Tamato. So don't take my opinion out of malice please. It's simply not meant to insult. Cheers! Zip~
Mike TTG - thanks so much for the clarification on LCt engines - for a long time I've thought they were chinese engines - as the are very similar to the smaller SV engines used om cheapo-push mowers.
not JUST good! A REAL LEARNING VIDEO. JIS SCREWS???? WOW THOUGHT I KNEW IT ALL AWSOME CLEANER, AGAIN WOW, FINALLY THE TEA SEEPING BASKET, WOW AGAIN a thousand thanks!! what is the story about the license plates???
My subscribers have been sending me Plates for about a year now. Some have gone above and beyond and found me plates with my birth year on them. Too cool, and each plate tells its own story. And I'm very glad that you enjoyed the video! There's over 900 more on my channel. Cheers! Zip~
It's an interesting design. Vents into the intake elbow so you're burning the gas vapors and the pressure in the tank stays regulated. Much line a fuel injected engine set up with a return line. But that MTD Engine! lol...I could have just removed the carb studs instead of unbolting the engine to get the carb off. Doh! lol Cheers Willy! Zip~
lol...The cheaply used materials to the decks that always rust out in a couple years, cross use of 9/10ths of the components to save a buck. I think the only thing they truly change between "brands" is the hood adornments. The hood shell is even the same across the brands. Someone always has to finish last. I guess since MTD sells SO many, they're ok with it. Mass produce, give them a year warranty and make sure nothing breaks in a year and then we'll make boat loads of cash on the replacement parts! Cheers Mike! Zip~
I am feeling pretty good after taking care of the Craftsman. If I didn't have the Ultrasonic cleaner I probably would have just replaced the carb. Fortunately, the cleaner did the trick. Cheers Joe! Zip~
You don't know what you are getting with those cheap replacement carbs, I've had to use the guts from my original carb before, because the replacement wouldn't run as is.
