Two thumbs up, Steve & April! Yes this was very informative! Knowing why things do what they do helps us know what they are also doing. If I tear my machine apart, I WILL NOT lose that spring! (Maybe...)

[@StevesSmallEngineSaloon]

Thank You...

[@Rsandman41]

It's a known fact that when you drop tiny parts they fall through the earth never to be seen again.LOL I tried everything from laying down sheets and working over old cooky sheets with a towel in the bottom to deaden the bounce. Kinda thinking evil spirits and not the drinking kind. LOL Take care you two great content as always.

[@peterlivingrooms119]

Thanks to your videos I was able to fix my dad's trimmer last Saturday adjusting the carburetor and changing the spark plug and the gas lines, he already have gave up with the "mechanics". Thanks, Sheers and blessings from Puerto Rico 🇵🇷🙏🏽❤🙏🏽 keep the good job my man💪🏾💪🏾

Love reading stories like yours, helping Dad with the problem solving tools Steve cranks out. Dad raised a kid I bet he’s very proud of. A good son. ¡Ándale! 👍

[@scottfirman]

I learned the importance of that spring working on older snowmobiles. It will not run without that silly spring. I see them on Briggs and Straton lawn mower carburetors under the diaphragm. Typical item . I learned a long time ago to work over a bench and have a towel under the carb to catch the bits that fall out.

[@stephenzies8867]

I've Been A Mechanic For Over 49 Years And Worked For Volkswagen And Audi Dealers For 33 Years. That Spring Looks Just Like The Accelerator Pump Spring On The Old Air Cooled Volkswagens Engine Carburetors

[@luulemees]

Thanks, Steve for breaking down physics behind a hole and a spring! so far i had no idea why exactly they are there for

[@StevesSmallEngineSaloon]

No problem 👍

[@Johnny53kgb-nsa]

That's partially why I don't take my carburetor off my equipment. I'd either loose a part, or have extra part's leftover, and end up taking it to a shop to be repaired. I stick to the basic repair's, like a tune up. Thanks!

[@TheLawnmowerLady]

Dropped one or two, but honestly never connected the dots. I like learning something new. Thanks Steve and April. Cheers!

[@StevesSmallEngineSaloon]

Right on Stella! Thank You...

[@Cacheola]

I knew that spring was for the fuel pump diaphragm and understood what it did, but didn't think about 2 stroke mechanics. Cool, thanks!

[@StevesSmallEngineSaloon]

You're Welcome...

[@jaym8027]

You two are treasures of the internet.

[@StevesSmallEngineSaloon]

WOW! Thank You...

[@williamlester6243]

It should also be noted that there is a small atmospheric vent into the pulse chamber under the pump diaphragm so the chamber with the spring doesn't fill with crankcase oil. This is the same concept as the small circular sintered bronze button on a hockey puck fuel pump to keep a slight flow of air through the pulse chamber keeping the crankcase oil in the engine.

[@matthewturowski8281]

You two make a great team. The rule in my garage is the smaller and more important the part the greater the chance of me losing it and never seeing it again.

[@StevesSmallEngineSaloon]

Thank You...

[@Willy12927]

April is a great addition to the videos.

[@StevesSmallEngineSaloon]

[@paulmcreynolds1774]

Great video. I knew where the spring was located and I knew if you lose it you are screwed but I didn't know exactly what it's purpose was. Great information.

I have 2 stihl 2 cycles, and a shindaiwa 2 cycle. Owned them for 20 years. This stuff doesnt go bad. I have no experience fixing 2 cycles, cause i have had no reason to fix them. The 2 cycles seem to have less problems than my 4 cycle carbs, which all needed a rebuild kit at least once

[@richardybanez9052]

Once Again April's Small Engine Saloon.Hits A Grandslam.😀😀 Richard.

[@691lucian]

I always wondered what that spring is for, I noticed only the 4cycles have them, never really thought it through as to why it has it lol I always just put them back in but it makes perfect sense now, thanks Steve!

[@StevesSmallEngineSaloon]

Glad to help

[@craighellberg4366]

[@iguanaamphibioustruck7352]

I got tire of paying $50 to my Stihl dealer for just cleaning the carb on my weed eater and chain saw. You have two fuel filters but I lost the one in the carb as well as the spring. I finally ordered a new carb for $12 and installed it with perfect running results. Did not even have to get the special tool to adjust the idle and mix. I learned the hard way about living the tools through the winter with ethanol gas. Now, I have the DeWalt 60v chainsaw, blower and weedeater and do not have to spend nice days working on my Stihl. Further, I do not allow anything but premium gas (non ethanol) on my property or in my vehicles.

[@jimwetzel1635]

Major props to Lady April, as she heroically maintains a straight face while Steve's talking about "That thing" (air) "going in and out of that hole." A true professional!

[@StevesSmallEngineSaloon]

[@ryanbruner8928]

I have to admit,I've never seen this spring. I've messed with lots of 2 stroke carbs,but the shop boss always did the 4 strokes! I don't work on stuff for people anymore,but this knowledge may come in handy someday?!!

I never did carbs. But I know what a accumulator spring does. Same shape. It slows the 1st 2nd shift so mom does not feel it as much. So a bit like that. But I also have never seen a fuel pump on small engines. Now I know why. I just thought it was all gravity.

[@stevengentry8648]

Thanks Steve & April ❤

[@StevesSmallEngineSaloon]

[@timwagster9458]

Wow! I have worked on too many fuel pumps because I knew right away. LOL Thank you for the awesome videos. It is like school for me. I have been watching many past episodes lately and wishing I had access to your videos years ago. 👍😁

[@StevesSmallEngineSaloon]

Thank you!

[@100vg]

Steve, you started talking about "in and out" and I though April would make your face turn red again, but No. I want a remake with Sarah Wayne Callies. 🤣😂🤣😂🤣 She wouldn't have missed the opportunity. 😝 But now I know why I've never seen one in a 2-stroke carb rebuild kit. And now I know I might find one if I ever have to work on or rebuild the 4-stroke carb in my Troy-Bilt Powerhead or my Pressure Washer. My Craftsman VTS DLS 3500 46" Deck tractor mower with a Briggs engine didn't have one. At least the original Nikki didn't, or at least I didn't see it. That could be the part that was lost. I replaced it with a Briggs OEM. I don't know about the Troy-Bilt Horse 46'' Deck tractor mower yet, but I may find out soon enough. It has a Kohler Courage SV470-SV620. I'm using the Craftsman while the Troy-Bilt is down for rust repair, but I like the Hydrostatic much better. Thanks, Steve and April. Another great one! Sorry my comments go on and on, but I like to share. I subscribed because I'm still learning and your channel is great.

Good one Steve and April. lot of the older Briggs used a spring with the diaphragm in the fuel intake manifolds.

[@scottmiteen4772]

Great video, one suggestion is to put a link or part number where the guy can get a replacement part or rebuild kit to help him out. 😊

[@marvley361]

Never knew what it was for but figured if it was there it belonged in that spot for a reason so I put back where it came from. Thanks for the info.

[@JeffLivingston-Ezlivin]

So is the difference because of the exhaust valve being open on the 4 stroke not causing negative pressure?

[@natesurmon3455]

Can you also make a video on all of your pistons collection that you have not like the Pistons scoring video just pistons in general? That you in own

[@teddycunningham7568]

Hey Steve! You and April are doing an amazing job answering all our questions and we really appreciate it. I have watched many of your videos and have learned a lot. I have a request for you to make a video of replacing the clutch and drum for the STIHL FS 45 weed eater. I hope you see my comment and as always thank you for making small engine repair fun!

[@rozco1978]

As soon as you said spring in the carburetor. My mind thought of the older B&S carburetor that is screwed to the fuel tank. Good information 👍🏼

[@StevesSmallEngineSaloon]

Right on

[@outdoorfreedom9778]

I knew that but!! But now I can't recall seeing the spring in the last carb I rebuilt? The engine still is doing the same thing, fires up then acts like it is out of fuel. Exactly what it was doing before the rebuild though. It's on my boat, chevy inboard and I planned on going into it one more time this spring. Now I'll be looking for that spring under the diaphragm!

[@dclawnmaintenanceandsnowre4099]

The only other engine I've seen spring similar to that was on Briggs & Stratton engines for tillers

[@joemcintyre2090]

Wow!! now I really understand the diaphragm carbs more! Now I will think of them as a carb with a built in fuel pump which I never thought about them that way before. In fact I was kinda scared of them because everyone I tried to rebuild didn't seem to work. So I'd just buy new ones.

[@dgkingster1]

Great information in a straight forward understandable explanation- well done

[@StevesSmallEngineSaloon]

Thank You...

[@markschoenhals4816]

Well sir I knew exactly what it was when I saw the spring. Does that make me an old guy. I know on the old Briggs there was a metal ring on top of the spring so it would not rub a hole in the diaphragm. Thanks for all you do you lucky dog.😊

[@tjclarke4604]

Oh my word, as soon as I feel one of the little springs fall from my hand, I know before it even hits the ground that I am already heading towards the scrap machine pile for another one, because there is absolutely no point looking for it on the floor, it's gone, lol. Same for the inlet needle spring on the metering side. I think those springs go meet up with the socks that go missing in the washing machine, wherever that secret place may be.

[@StevesSmallEngineSaloon]

So a two stroke has a wee heartbeat, too cool. 😊 So without da spring a four stroke s heart fails and it dies. So if your diaphragm or spring fail your machine has in effect a heart attack and will die. No gas flow means no life. 😢 This some very interesting stuff indeed. I love the education you give us for free. Thanks so very much for your time and hard work.
