I was also impressed with your method of cleaning the rusty fuel tank. I have plenty of old nuts and bolts in my workshop which will do the trick. I have used other items in the past but never achieved an excellent job like yours.🙂🚜🐻 Bear Queensland Oztralia.
They work well, and it's pretty easy to get them all back out once you finish.
Enjoy how dudes with chunky fingers make busting screws loose easy! Thanks for the video sir!!

Recently putchased a Lawn Chief tiller with this engine. Cleaned carb,fresh fuel n it started on 3rd pull.According to numbers on engine it was manufactured in 1982.
They are great little engines for what they are designed to do. I’ve seen quite a few still in operation even from the 70’s.
i have a 40yr old concrete mixer with a B&S engine and carburetor. it has stood unused for several years and refused to start.. following your video it's now running like a dream. Many Thanks. Alan, County Durham, England,
That’s awesome! It sounds like hard work starts now! 👷♂️👷👷♀️
@@baldeagle242 Correct. We recently bought a 300yr old house so I'm going to need my mixer!!
@@alantownsend4571 That’s awesome. 😁👍
The muffler and the governor linkage - classic doh's. Thanks for a good video.
Thank you for the tip of counting how many turns of the needle valve.
Been told and it worked for me on a forty year old tiller with a five horse powered Briggs is when you done with this type of metal tank is when your finished using it too keep it full of gas . This way and I did keep it full of gas and it didn't rust up any . Had an old friend that trained me too work on them right at forty years ago too use this method . Thanks for the video ......
Good video! Appreciate your close up photography and detailed explanations!
Hi Baldeagle,
Like so many petrol heads i just can not walk past an old engine that is looking sad And so "much to her who must be obeyed" (the wife)
I bought this old sad looking french rotovator that had not been working for years, when it came to the carb, i found it was a Briggs and Stratton Pulsa jet , and your video is just as good as it gets and i have so much to look forward to when i get out into my Den and get to work on it,
Thank you Baldeagle,
(peace perfect peace in that Den, so quiet i swear you could hear a mouse fart "but not her indoors")
I'm the same way. It brings joy to my heart to get an old engine running that's been neglected for sometimes decades.
Good luck with your project and keep your beans dry and sealed around those little rodents. 🤣👍
@@baldeagle242 I’ve been working on a 3hp briggs & stratton everything is looking good except the carburetor is missing parts to throttle up and down.
@@VtPapa Thanks for watching. I didn't go into much detail about the linkage in this video, but I have a good video on a 5hp go-kart where I had to rebuild the entire linkage to get everything working as it should. Here's a link to that video.
th-cam.com/video/iiYzqqzqGc8/w-d-xo.html
Great job, hate the ol muffler got ya
It's all good. Made a good outtake for the very end.
Man I have done a few of those carbs.
I wish they were still made like this. Thanks for watching. 🦅🇺🇸
Great detailed video on that pulsa prime. Let this old flathead run for another 40 years!! 💪. Got a chuckle on the muffler first. I’m sure I would have done the same.
I can't recall ever having another one of these that I could not get the muffler on or off without removing the carb. Thanks for watching my friend!
@@baldeagle242 probably most applications run a straight shaft muffler instead of that 45 angle.
Awesome video Steve! Keep up the great work.
Thanks, Johnny; I appreciate the kind words. Thanks for watching.
Didn’t see but 8/9 rotor tiller this year because it’s so dry here but if it rains normal then back to 30/45 again
Great job of cleaning it up and I hate they don’t have a tank drain
5:19 course lag bolts or screws work absolutely great using this method along with white vinegar or maybe muriatic acid but use the acid with caution and at your own risks! The white vinegar is definitely the safer, simpler, option.
Great video!!!
Thank you. 😁👍
Baldeagle, i feel like an idiot. I didn't even know you had a TH-cam channel until i read your comment today on D&R Engines video. I am a subscriber now. I watched your last two videos and i going to watch several more today. I like your theory about keeping videos short and informative! I look forward to following your channel in the future. 👍🇺🇸Roger
Thank you, Roger; I hope you find some value in the videos. 🦅🇺🇸
Thank you for the help,I have an old 5 horse briggs very similar to this 3hp version and it was revving too high because there is no gaskets to i have ordered a kit for them and i used this video to help me do this cos im only a beginner really so thanks for the help
ty very much from france !!!
there is no help for this carburetor...
ty bro
You're welcome. Thanks for watching.
Good video. I have a 1974 3hp horizontal shaft B&S also.
Thank you. 😁👍
If you add a fuel tank drain braze it with as little heat as you can, most of tank sealer is gone on these tanks by now and don’t hurt any thing
Why don't people add "Fuel Stabil" by Golden Eagle for short term or long term storage?
Another simple trick is to find a local boat dealer! Why! They sell outboard engines and many of the fishing boats and pontoons have fuel tanks built in. What people don't know is that each engine comes in a create with a fuel tank, hose, squeeze bulb and engine fitting. The parts dept have these stacked to the ceiling and can't get rid of them. These tanks are given away, thrown in the trash or sold for pennes on the dollar. They all come in odd numbers like 3 gallons, 6 gallons and such. Remove the hose end fitting, install a cheap peacock, and mark one for oil mix or 2 stroke, and the larger one for straight gas. Use gravity to unroll the hose, place in the weed eater or chainsaw and open the valve. If the tank is high and the tool is low, a siphon will allow you to accurately fill the tank without spillage. Do not let the little hydrocarbons escape an run free into the 10k atmosphere as it creates photo smog. Stuff you can see! Otherwise, I don't care but some people from the Sierra Club may faint! Remember,
Don't let the cows fart,
Don't let June bugs make ducks dart,
Never let frogs create art,
And don't pass gas near uncle Art. He smokes a pipe, it may lite!
Good video. I have an old 45 year old tiller with the same engine. One question is how did you remove the fuel tank? How many bolts are holding it on and where are they?
Good job !
Thank you. 😁👍
Very nice💥
+@jamesrichardson771 Thanks for watching! Here’s a link to other videos I’ve posted that you may find useful. th-cam.com/play/PL5_ZXmQpcjpac4UV8OW8g-IWVCR8tqy79.html&si=RKfnQL-PAcZFy67a
Any tricks on getting the carburetor off the engine a lil easier/ faster ?? Man it sucks
There's no easy way on this engine. If you have the offset muffler, make sure you don't forget to put it back on first, so you don't have to do it twice. 🤦🏻♂️
I picked up a snowblower that has the same carburetor and this is the only video I saw so far rebuilding it.
I can look it up but what was holding the jet in?
A screw of what flavor?
Great video this is what youtube was built on.
Thanks a million
Where to find the kits for these older motor referbs??? I have two I need to do but can’t find the parts to star the jobs . Help!
If you’re just looking to rebuild one or two the easiest place to find them is on Amazon.
amzn.to/3sHbNqN
If you can't find it on eBay it doesn't exist.
I’m talking about the thing you pull at 7:05 into your video.
Yes, that is the choke pull. I'm not sure if you can purchase that or not. If I were you id keep an eye on marketplace and eBay for a parts carb or maybe even an entire parts mower. If I had a spare, id send you one.
Sir. I normally don’t leave comments, but I just had to let you know how much I thought of your video. TIP TOP my good man! Awesome! I’m having trouble with my old 5hp Briggs and Stratton. It’s I bought an aftermarket carburetor and I’m having issues with it. After I squirt a tiny bit of gas in the carburetor it cranks, but I have to keep my hand over the intake where the air filter fits down over it.. It has a pretty good suction on my hand abs when I take my hand off the intake to quickly put the air filter on my engine dies. I’m assuming the carburetor is getting to much air. Ive checked the diagram and about everything you can check. I don’t like the seal of the gasket that goes in between the carburetor and the tank. I think it’s leaking and possibly pulling air also. That might be why I have to squirt a tiny bit of gas in the carburetor to get the engine started. Any ideas would be greatly appreciated sir. Thank you.
It sounds like you are on the right track. From what you’re saying it has to be sucking air somewhere or possible the fuel tube is sucking air. Either way I’d pull it apart and look closely at it. Good luck with it and let me know what you find.
I have a 1974 80202 Briggs with the Pulsa Jet carb. What's the best way to get the manual choke unstuck, without damaging it?
If you have an ultrasonic parts washer put it in there on medium warm with water and Dawn dish soap.
If not carb cleaner and a few good penetrating soaks may do it.
This is all assuming it’s just gummed up and not damaged.
Awesome part 2 . Looks like you have a very inexpensive compressor. I have been looking for a cheap compressor here at home. Haven't found one yet. Bear Queensland Oztralia.
I've been looking for a gas-powered compressor for some time. Thanks for watching. 😁👍
Have this carb , mine runs great except the manual choke works it way to open position when running turning it's own choke on. I have to push it back in constantly. What causes this and how to stop this issue?
3 turns on that main jet seems like it is running too rich. 2 turns is all it should take on a 5
Nice rebuilding instructable. Thanks for spending the time to share
Thank you. 😁👍
Is there a tool that allows you to get the bottom 2 screws of the diaphram cover off without having to tale the muffler off? Mine has an oval muffler & you have to dismantle half the motor & tiller to get the tank off to get the muffler off just to change the gasket. I will be replacing it with a round one for sure.
I'm not aware of one. It's a PIA for sure.
Good video. I'm working on a 45 Scott Bonnar
Nice!
@@baldeagle242 I need these videos. Just think you are helping a guy in Australia
@@graeme1744 I've always wanted to come visit Australia!
@@baldeagle242 many good places to travel. I've been to America twice in 2001 and 2006
@graeme1744 Awesome, there are plenty of interesting places here. Where did you visit?
Just today tried to get my 5hp Troybuilt tiller carb running better, with same carb. It was constantly flooding but still runs slowly. Air filter no issue as it runs same with filter off. I did the same breakdown and cleaning but when put back together, stills runs the same. Odd that it runs better about 60 seconds before it runs out of gas. ANY SUGGESTIONS? I didn't have a rebuild kit so didn't replace any gaskets. Only other thing I wonder about is; I think it was running good this summer before I changed oil. Maybe I overfilled oil. I will try tomorrow to take out a few ounces so it won't run out fill cap and see if that is the problem. Maybe it is burning extra oil instead of gas, but wouldn't that make it smoke?
Thanks for your video and any help.
If you’re able to send a short video showing what it does that may help to understand it better. Me email address is on my about page on TH-cam.
Very nice video and great to hear that engine running so smoothly, too bad about the muffler. Only concern i have is the compressor tank condition on the inside due to age. Basically a ticking time bomb when pressurised if the wall thickness has deteriorated due to rusting inside. We routinely drain any water from ours every 2 or 3 days in the warmer months due to high humidity and once per week during the winter months since the shop is heated.
Thanks for the feedback, Wayne. I have the same concern about the tank. There's no way to tell how much it's deteriorated on the inside. Even testing it for the video, I was reluctant to let it pump much past 70psi. I haven't tried to adjust it yet but ill probably set it up to top off around 50 or 60 psi. That's more than I'll need to blow up a mower or utility trailer tire.
Thanks for watching. 🦅🇺🇸
I removed all the screws from the carburetor to the gas tank but how come it so hard to separate it? I don't want to brake it by forcing it off. Do you have any recommendations on how to separate the carb from the gas tank
I use a small screwdriver to pry it slowly.
An advert after one minute 26 seconds .
About 6 moths ago TH-cam took away creators ability to remove mid roll ads. I hate them myself and wish it were easier to limit them without signing up for their premium service. I finally gave in and signed up which is exactly what they want us all to do. 🤦🏻
I have a 5 horsepower yard king tiller with a pulse jet carburetor. I bought new everything fit up nice. It'll start right up. It will not stay running. Any suggestions?
Is it getting good spark and fuel tank is clean? Also make sure choke is fully open with no obstructions and a clean air filter.
If it has a low oil sensor make sure it’s working and oil is full.
Is there a conversion carb with a bowl and twist throttle attachment? 2 hp briggs
I have seen others do this on go carts before. I would look at some of the setups they use on racing carts. I’m pretty sure they will have what you’re looking for.
My tank doesn't have that reservoir to draw gas from, but has the short tube that would go into it. Where did it go?
That's interesting. 🤷🏻♂️
@@baldeagle242 I was thinking of trying to make and install one, but seems easier said than done.
What if I switch the tubes around, with the long one going to the main jet?
@@frankschwartz7405 I've never tried to do that. You may need a long tube on both of them for that to work. If you replace the long tube with a short tube, it will suck air once the fuel drops below the bottom.
I've always been able to source another tank when I have a bad one. Maybe someone else has a better answer?
@@baldeagle242 It runs, but not "like a top". It's picking up fuel, but it seems impossible to get the mixture right, Either too rich or it quits.
Guess I'll have to go to the lawnmower junkyard.
Is yours a 2 hp? Mine only has one tube going into the tank.
Bought an old tiller with a 5hp Briggs with this carb setup. It was surging bad and not revving up very good. I took the carb off and it was nasty and the pickup tube was bad. I cleaned the tank good and put a new ebay carb on it. It revs good now,but I still have surging and now backfiring like it's running lean. It does it at all rpms. You have any idea what else I can do to it?
Take a look at your coil and flywheel. Surface rust can build up on both pickups and give you a few headaches
@@tessahiebert8766 I did,but I think the problem is the fuel tank. The carb draws fuel from a pot/sump in the tank and it has pin holes in it. Apparently the fuel is leaking back into the tank depriving the engine of fuel. I tried to seal it with jb weld,but it didnt help. No one makes a fuel tank for it anymore,so options are limited. I've got a new predator engine in a box that my son in law had given me. I'll probably see if I can switch it out. It's a rear tine tillsmith tiller that's built like a tank. It's hard to handle because it's got no reverse and only one speed,but itll dig up a garden,lol.
How much compression for a similar 1978 B&S engine (080202-0855) should be?
You said that yours started at zero (0) compression and I believe, after repair, you brought it to 60?
Anything over 90psi is good. Most engines will still run at 60 but may be challenging to start and down on power. I don't recall checking this one after I cleaned up the valve, but my guess is it was closer to 90.
Even though this was an older engine it showed limited usage over the years.
Good day. Awesome video. Doing a go kart project with my boy. We seem to be missing the part that is at the back of the carb. I believe you called it a carb pump. What does that do exactly. This is a go kart I used to drive as a kid 25 years ago lol. We used to just plug that hole with a rag to get it started when the engine was cold. If you could let me know what that part is exactly it would be much appreciated. I can’t seem to find anything online about it.
I believe you're referring to the choke pull?
I believe you are 100% correct about that. Not sure how the whole assembly looks and works as none of it is existant on this old beast haha. But makes sense as plugging that whole with a rag to choke it used to get it going. With that piece not being there I would assume that would wreak havoc on the whole air/fuel mixture screw setting. Used to reach around and turn that screw in and out while I was driving it as a kid. Was like redneck horsepower tuning. Hahaha.
What is that tube that goes from the side of the choke to the block for, and does it matter if the boots are loose? I got a free generator with the same engine and carb, but the throttle is different and so far I cleaned the points and got spark, I got it to run off of carb cleaner for a few seconds but then it just dies. I've been all over TH-cam and this is the best video I have found showing how this carb works. I think before I go further I wanna get a lamp and make sure the generator part still works. Anyways thanks to anyone for some advice!
That tube is for crank case blow by. If it’s loose you can take a small plastic tie wrap and put it around the boot to tighten it up.
@@baldeagle242 I was gonna try some zip ties, just wasn't sure what it does or how air tight it needs to be.
@@natedavis3943 it does not need to be super air tight.
@@baldeagle242 Thank you!
@@baldeagle242 can you explain in more detail this tube for crank case blow by? Also, a friend gave me a rotor tiller with 5hp with this crb setup. He said the motor would vapor lock and shut down. Have you heard of this before or maybe something else? Thnx K
What is the other smaller compartment in the gas tank for?
That’s where the carburetor picks up fuel. It’s common for these to rust out and the tank has to be replaced.
@@baldeagle242 thanks!
How many times have I done something like that I wouldn't want to count 😩
I had to tell on myself on this one. 😁
Thanks for watching @Bill Clement.
I have a 2 hp with a similar carburetor but it looks like only one pickup goes in the tank and it doesn't have the diaphragm. Have you seen one like that?
I don’t see to many of these old Briggs engines anymore. This was a 3.5hp. Most of the ones I’ve had were 5hp and had a similar version to what’s on this one. If the tank is mounted below the carb it will have to have some type of pump to pull fuel up into the carb.
@Baldeagle242 after looking at it, I think the 2 hp has the small flat tank so the pickup just goes right in the tank and it doesn't need a pump to bring fuel up. It looks like the same exact carb with just the short pickup and no diaphragm pump.
@@GertTown ok, it must use the vacuum from the carb itself. I believe I have a 2hp in my parts shed. I’ll have to look at it next time I’m out there. 😁👍
@@baldeagle242 thanks
I’ve got a 3 hp briggs and Stratton magnetron engine on shingle left that has a new carburetor and still will not start less using starter fluid. Does anyone know what I might be overlooking? Thank you.
Is the diagram good in the pump?
@@baldeagle242 yes
@@stevengray8369 without looking at it in person it’s tuff to say. The pickup tube could be sucking air, diaphragm damaged or maybe something clogged up or even damaged. I know you mentioned it’s new but if it runs on starting fluid and will not run on gas I’d first confirm you have new fresh fuel and if that checks out ok I’d pull it apart and see what’s going on with it. I’ve had new carbs with problems in the past. You just never know till you check.
I have an engine like that one on a tiller, it seems to run fine but if I shake the tiller around or bounce it, the engine cuts out and doesn't run smooth? do you have any thing that might cause this.
@MissouriOldTimer Does it do this when the tank is completely full or only when the tank is less than full?
@@baldeagle242 I wondered if it was a cracked pickup tube so I took the carb off the tank again and that was all good, I re cleaned it and put a new diaphragm in and base gasket and now it works as it should. thanks for commenting.
@@MissouriOldTimer Awesome. I’m happy to hear you got it going and hope to see you around on future videos. 😁👍
@baldeagle242 my carb leaks when it's running any info would help?
is the carb on top of the tank like a tiller or on the side like most lawn mowers?@@AA-dg3ig

@@RahanComhaltas unfortunately a lot of sellers have no stock on many common items. I’m working on a few things right now that parts are back ordered on. 🤦🏻
Great video but it was over too quick. Do it again. Just kidding. I had one of those engines on a mini bike I had as a kid that thing would go 30 mph. Very tough engines. Keep up the great videos.
Thanks for watching, Jerry. The one I had on a mini-bike as a kid didn't have a recoil starter rope on it. You had to carry the starter rope with you and wrap it around to start the engine. No idea what year that motor was but I know it was a early Briggs that my grandpa gave me. Once the clutch was worn out I jammed sticks in the clutch and push-started it so I could still ride it. All good as long as you didn't need to stop. 🤣
@@baldeagle242 Well at least you did not have to carry the rope with you anymore. what did you do if you had to stop kill the engine? I bet you were just praying that no dog or cat ran out in front of you.
It had the same spark plug grounder like the one in this video. I'd reach down and shut it off. I also found out if you flipped it off and coasted for a short period of time and then reached down and flipped it back on it would backfire and shoot out a fireball. 🤣
Back in my childhood days you had to learn how to live without all the safety stuff we have on everything now. 😉
@@baldeagle242 We used to screw a metal water pipe about 6 inches long instead of the muffler and it would sound so good and loud and when you let off of the gas it would shoot out a fireball. Man the good old days I miss them so much. Kids today don't know what real fun is.
I couldn't agree more. It sounds like you and I would have had a blast together as kids. 😁👍
Thank you for the help,I have an old 5 horse briggs very similar to this 3hp version and it was revving too high because there is no gaskets to i have ordered a kit for them and i used this video to help me do this cos im only a beginner really so thanks for the help
