BRIGGS OPPOSED TWIN ENGINE CARBURETOR GAS FUEL SHOOTING POURING FLOODING OUT RUNS ON CHOKE *SOLVED*

[@mikespain8655]

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.

No way? Same thing? What are the chances?

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

[@lawrencecarroll2031]

Without doubt; that screw in the valve is the wildest thing I've ever seen n an engine!! GREAT video and job Henry!!

[@MowersNBlowers]

First for me too buddy! Very interesting

[@Don_ECHOguy]

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! 👍

[@MowersNBlowers]

Yes, wheelbarrow tube!

[@fred306801]

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.

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.

[@Don_ECHOguy]

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

[@MowersNBlowers]

My quads aren’t even sore!

[@deekw7519]

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

[@billflying2977]

On cue at 46:47 mans best friend lol. That's awesome Henry! Wonderful trouble shooting

[@knighthawk86855]

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.

[@MowersNBlowers]

Exactly!

[@knighthawk86855]

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.

[@larryamatulli9224]

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.

[@bassworship50]

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.

[@MowersNBlowers]

My issue was one cylinder wasn’t working, I swapped out a new ignition coil, both cylinders running cleared up my flooding.

[@Turningwrenches85]

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.

[@alfredodirks3537]

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’ve wanted to try flex seal, but pretty expensive, I think it’s just like silicone which I love

[@alfredodirks3537]

@@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.

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?

[@MowersNBlowers]

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

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?
