Got a free Craftsman 19 up opposed twin Briggs and Stratton this year. Same problem, carb screw in intake valve. Ground and lapped all valves, runs great.
Thanks for the video I have been trying to help my Dad figure out his issue with his mower I was about to order a carb tonight and seen this video and his only runs on choke, I already cleaned the carb and it shoots gas out just like this one did and we put on a new coil already because it quit firing but now I think we better get out the compression tester. Thanks again great content and great channel keep up the good job! Dave
Was watching it run after the new carb install and thought the same thing, is it running on both cyls... it was like an air pump shooting back through the carb. This is why you put a drop of loctite on the butterfly screws when you reinstall them! That looked like a wheel barrow tube in that rear rim too, I changed a wheel barrow tube a few days ago and it looked about the same size. Very good educational vid bro! 👍
That's awesome man... Who would of thunk it huh, just glad that screw didn't do more damage, sweeeeeeet..... I had one of the oppys, that the bent over part of the spark plug had broken off, and banged around in the head, made dents in the head and piston but once I got the broken part out, and a new plug it ran perfectly.
How sweet was that bro! No damage from the screw either. Too bad you bought a carb you probably don't need. I'd put an old one on and keep the new one. Probably nothing wrong with it.
Several years ago I worked in a place that recapped tires. Mainly for big rigs. Sometimes we would get in some rusted up tire on a rim kind of like what you had. The company had machines that would take the tires off. But people like you and I are not so lucky. What works for me is to wait, if you can, for a Hot dry day and set the tire on some concrete and let it bake in the sun. The rubber gets soft and is easier to work with. It makes taking the tires on and off a lot easier. Also we used a Dremel tool with a wire brush to clean the rim. They had some kind of spray sealer, something like rust oleum, that was sprayed inside the rim where the tube goes. They claimed it would stop it from rusting. The great brown nose, I mean Asst. Boss said, Rust will puncher a innertube. I bought a used mower and the guy gave me 3 carbs. all of them are from China. I screwed around with them for a few weeks. I got one of them to some what work. Briggs 20 hp opposed twin. I can get almost up to 3000 rpms. then it starts acting like it is flooding out. So I asked the guy at the local mower shop. He said that these carbs are junk. He said he could get them to work., most of the time. But many of them surge and do not ever run right. And they will not last. I gave $125 for the mower and Briggs wants, I think it was over $300 for the carb.
Henry, I have a portable air compressor on wheels, but instead of dragging it all over the 4 acres that I have, I use a (9 Gal) portable air tank that's good to 125PSI. I can usually top up half dozen tires or more in just a few minutes and it's handy to throw in the pickup too. Was watching you with that foot pump... hope ya don't get athletes foot. lol
I bought one of those dual chamber foot pumps last year it comes in so handy when I'm at a customers house and he/she doesn't have power near the tractor..... I have a big compressor in my van, and a gas powered generator but it's so much faster with the foot pump, cause sometimes I can't get my van to the tractor sitting in the middle of their yard, and I can pump it up enough to get the tractor to my van for the rest of the inflation.
well that was one thing i didn't think of a screw in the intake that got by, i though maybe a head gasket going out when u took the head off of there lucky it didn't go all the way through, but at least that solved the problem and then u went to get a Chinese copy for $28 but now u got 2 good OEM carbs u come across another opposed twin that needs it.
Good day Interesting video. Boy luck that screw didn't go in farther. Boy Boba seen something interesting when usi ng foot pump. But those big hand pumps that you set on ground, piston cyl is alot bigger that foot pump. But it like u said, how much did fellow make after expenses. I like watching Boba come in on screen..Thanks
Replace your fuel pump if it’s not pumping. Test your middle line to the fuel pump, is it pulsing? Check the hose for vacuum leaks. Try a gravity gas tank or soda bottle with gas directly to the carb, if it works, then it’s your fuel pump
It's a lot of fun when the lost nut/screw/bolt does that to a drag car engine. Have you or anyone on your channel like Jason tried spraying or brushing Flexseal the black rubbery stuff on inside of tires? I was wondering if it seals dry rot. or at least help protect from getting leaks.
@@MowersNBlowers I watched my neighbor use the black spray on a corner peak asphalt shingle. It looks like rubber undercoating but not as oily and gets a hard shell even though it's still flexible. I'd guess the brush on would be better so you have more control of it.
My craftsman ltx1000 ran fine and put some gas in it. Started drove 5 feet then quit. Then didn't start change the fuel filter nothing. Pulled the carb off had bunch of crap in it. Cleaned the jets and the float was gummed up. It starts now but gas is shooting out the top. Think the needle is the problem. What do you think? Any thoughts would be appreciated.
Looking like the float was not closing all the way so that is why I decided to try a new needle I don't have a clue what I am doing don't know nothing about carbs and motors
All you need is a good portable air tank put a good 125pri and you could blow up a half dozen before you fill it or get a cheap harbor freight 12volt compressor and put some clamps from old battery charger and use the tractor battery it self.
I NEED HELP ... I'm loosing my patience. I have 17hr opposed twin. Flooding badly cant keep it running. Fuel even coming out the top of the carb. So I rebuilt it professionally. Same problem. So I got a knock off carb from Ebay. Still doing the same thing. Has spark. New plugs. Has compression. Wish I know how to send u a video just so u can see it for yur self. ANY IDEA'S what it could be. It's a 4hole carb
@@MowersNBlowers Well Both plugs are firing so the coil is good & I replaced the spark plugs. ? ? . Wish I could send u a video. It's just doesn't make sense
@@MowersNBlowers I understand. I did a compression check little over 117psi on both sides. I have done everything. I can think of. Then I went to TH-cam to see if anyone has answers. Yur video's are very good & I had to ask u . For help.
float level too high, bend the float arm some and try again. something stuck in the needle/seat of fuel inlet? mine did that ... old carb, sat outside for long time, water in it... water freezes and the brass float .. .sinks in the fuel bowl and gas comes spurting out of vent. new carb on the way.
I have the 19.5 died out while mowing full blast blows gas out of the carb like the one in this video was doing. I tried a brand new carb same result. I have 120 lbs compression on both sides and had it running long enough to spray both manifolds that steamed up good so I'm confident it's running on 2 cylinders. I have spark checked the keyway it's good what else can be the problem? Something happened while I was running full blast drained oil no metal and no gas in oil tried a fresh fuel source from separate fuel line as well
Henry what model carb did you buy? I have the the same carb but it keep flooding like a giezer in the throat and floods over the Top also. It's getting way to much gas
Whoa whoa Henry, you gotta be careful using those NYS illegal bags in your videos....ESP a red one. LOL No way in hell did I think youd find a screw hanging out of a valve when you opened that up. Is that the most unusual thing you've ever found in something? You've gotta have some stories about that....
On cue at 46:47 mans best friend lol. That's awesome Henry! Wonderful trouble shooting

No way? Same thing? What are the chances?
@@MowersNBlowers any idea where the screw came from? Could you tell if yours was a carb screw as well?
@@BenDover4Mee it’s the screw that attached the air filter base on

Great work Henry, love how you stuck with it till the end. I did miss the lavalier today. You have spoiled me with your new sound.
Yes, the lavalier really works great! I guess what I had was technical difficulties!

Good diagnose on that bro thank God that the screw got hung up on the intake and didn't go into the piston cuz then she would have been done ski

I'm having an issue with my oppose twin 20hp briggs flooding, maybe i'll check mine for compression and go from there. Thanks for this video.
My issue was one cylinder wasn’t working, I swapped out a new ignition coil, both cylinders running cleared up my flooding.

Sure wish you put the old one back on to make sure. I have 105L and 115R compression with the same issue on old carb, driving me NUTS!!
Those are decent numbers
Having same problem 20 hp opposed Craftsman Lt 1000 going to check cylinder for same issues
You had a screw stick in your valve?

Good thing that screw got jammed in that valve. Kept it from getting into the cylinder.
Never thought I’d find that
I have a 20.5hp Briggs opposed twin. Fuel isn’t pumping to carb. I replaced the gaskets, diaphragm etc. Still no gas. Any thoughts?
Replace your fuel pump if it’s not pumping. Test your middle line to the fuel pump, is it pulsing? Check the hose for vacuum leaks. Try a gravity gas tank or soda bottle with gas directly to the carb, if it works, then it’s your fuel pump
hey henry i have the same crappy carb and the same engine how do i stop it from surging?
Surging is always the carburetor
I think the carb is on upside down. It's blowing the wrong way.
It's a lot of fun when the lost nut/screw/bolt does that to a drag car engine. Have you or anyone on your channel like Jason tried spraying or brushing Flexseal the black rubbery stuff on inside of tires? I was wondering if it seals dry rot. or at least help protect from getting leaks.
I’ve wanted to try flex seal, but pretty expensive, I think it’s just like silicone which I love
@@MowersNBlowers I watched my neighbor use the black spray on a corner peak asphalt shingle. It looks like rubber undercoating but not as oily and gets a hard shell even though it's still flexible. I'd guess the brush on would be better so you have more control of it.
should always put a new head gasket on, they crush when tightened. who knows how long it will hold compression down the road
I agree

Valves aren’t seating so too much fuel is shooting.
@@MowersNBlowers got new needle ordered
@@deanwest7623 did you first check your existing needle? If it’s fine, what would a new needle do?

@@MowersNBlowers put new needle in stopped the gas leaking out the top but runs wide open now have no control of the throttle everything moves freely

This video is a bunch of years old, I have a ton of tire inflators
Can I have a link or website to buy a carburetor for my twin engine craftsman
You have a craftsman with twin engines? Or you mean opposed twin? You want original Or Chinese copy?
got something going on in one of your cylinders

Did you make sure both cylinders are working, because that was my problem
Here is the Chinese copy carb

Henry, where did you get that jack for your riding mower?
It’s just a regular 1 ton floor jack
Why is the gas fuel pouring and flooding out of the carburetor?
Watch the video and find out!!
I don't think that twin has a carb issue. I think a valve is stuck open or cracked and judging by the sound it sounds like it's running on 1 cylinder
Didn’t watch the video huh?
@@MowersNBlowers I watched it and it was great but I was offering my guess of what the problem was.
Trevor Wiles well then you were right on target my man!
Family dollar and dollar General sell 12 volt air compressor for 10-12 dollars cut end off and put alligator clamps on hook to battery and air up tire
The past few videos I was thinking it sounded like a single cylinder engine, but I never thought anything of it
Can you add the info on to where to order that carb? I need the exact same model.
