Glad you enjoyed it! Go to Amazon and type in the model of your carburetor :)

[@n085fs]

Your small engine carb was made by either Walbro or Zama. There are a few other makers, but those are the most common. I think it was Walbro that actually developed this pump in metal, so it eliminates the fault of it ever becoming stiff. The upgrade to metal is definitely worth it for small engines that sit stored during winter.

I'm in Montana where we run vintage saws alot. I recently installed 4 cheap Chinese replacement carburetors. Two ran good, two did not. What is your opinion about the durablity of these carburetors? @@VintageEngineRepairs

[@karljay7473]

If you can't find the part you need, you can use the one you have as a template. I used to reman carbs back in college and we used to grind off the metal plate in the center of a diaphragm, make the new one from another diaphragm using a hole punch (gasket making kit) and them attach the old metal center part.

[@VintageEngineRepairs]

Thanks for sharing! :)

[@AyuPerezsaucedo]

Me puedes decir por favor cómo pules el centro el metal del centro del diagrama por favor gracias

[@karljay7473]

@@AyuPerezsaucedo When I rebuild a diaphragm, I remove as little metal as I can. I start with a small chisel and hammer. I hit the center of the diaphragm towards the center. Then, if needed, I grind away a any part of the center that is still holding the diaphragm together. A punch in the very center, usually gets the two metal parts to separate from each other. Then I replace the rubber part, usually from one pulled from a new part. Then red Loctite and pound the center metal back to where it holds it together. I never polish them, but you can create a nice smooth surface with a Dremal with a grinding tip.

[@andrewstambaugh8030]

Very nice demonstration and discussion of when this makes sense or doesn't. You are totally right, often people only need that tool that has dried out and gone crusty for just a weekend or so. If you've gone off to a cabin in the woods, you may not even have a mailbox or internet to order a new part. If you get it soaking overnight, you can probably get the use of it the next day.

[@99nadroj]

Not just diaphragms, many things made of rubber respond this way - but only temporarily unfortunately. That can be useful, for example to install something that needs to be stretched into place. In my experience, complete hardness will return before long. I haven't tried, but could it be that the products made to rejuvenate hard oil seals might work better? These contain a "seal swell" ingredient, added into car gearboxes for example. I've also heard that wintergreen (methyl salicylate) can usefully soften hardened rubber.

[@VintageEngineRepairs]

Yep agreed :) thanks for sharing!

[@desertodavid]

@99nad, thanks a million for that tip about using methyl salicylate (Wintergreen) instead of brake fluid for softening rubber long-term. I actually have some creams that contain it, used for aches and pains in your joints and muscles

[@idonotwantahandle2]

I'll try the wintergreen for inlet rubbers. Ester oil softens and swells elastomers whereas PAO oils tended to harden and shrink them until gasket compatibility became part of oil certification.

A little bit of brake fluid also softens internal seals on automatic transmissions, making the old transmissions shift better. Once Transmission starts shifting well again, change the fluid.

[@VintageEngineRepairs]

Thanks for sharing :)

[@tomrogers9467]

Yeah, you won’t have ANY leaks after you replace the transmission that the brake fluid destroyed!

[@gueto70]

Old car mechanics trick. If you have gaskets or seals leaking, dump half quart of break fluid into your engine oil. It softens and swells rubber seals for a quick fix. As soon as the leak stops you change the oil and as soon as you can, you replace the bad seal. It is just to get you to your day off or payday but used car dealers used it to temporarily hide problems.

[@jpol3808]

Excellent video and presentation. Like you stated it's not permanent but it does have merit to the technique for sure. Good job!

[@VintageEngineRepairs]

Glad you liked it! Certainly give it a go and report back :)

[@mikek1187]

The best method that I've seen is a 3:1 IPA to essential wintergreen oil mixture to soften rubber. Problem with brake fluid is over time, the rubber will "sweat" out the brake fluid. The other method IMO, is more permanent, but more expensive.

[@VintageEngineRepairs]

Yes I have heard of this too! I saw a video doing comparisons - very interesting!!

[@sonicdewd]

Wintergreen oil, 1 hour, and moderate heat works much better and is much more permanent. The brake fluid tends to sweat out of the material.

[@VintageEngineRepairs]

Thanks Paul! I’ll have to give it a go!

[@sonicdewd]

​@@VintageEngineRepairs Thanks for the reply! I've tried both just to let you know. One thing that I haven't tried is this: On a machine that has been sitting up for a while and you know that the metering diaphragm is too stiff, I'm going to try to squirt some wintergreen oil through the little breather hole of the metal cover that covers this diaphragm and just put it away for a week or so. This would eliminate the need to disassemble anything. My question so far is whether the wintergreen oil will deteriorate anything - that I don't know yet and I haven't been able to find info on this online. Some people make a potion of alcohol and wintergreen oil. I think this is a dubious way to go because alcohol is the thing that hardened the material in the first place. Just pure wintergreen oil, and your whole workshop will smell either like an urgent care facility or an old geezer's home lol Another thing that I'd like to try is a suggestion from Chickanic where she pumps (with the little primer bulb) pure 2-cycle oil through the carb before storing the machine for the winter. She says this really works and the equipment works for "years" with little issue. Last thing for the readers here - always use alcohol free gasoline. Just make it yourself. In a vegetable juice plastic container (clear plastic) or similar, put 1/5 water to 4/5ths gasoline (this ratio is NOT critical), shake it, let it stand for 5 minutes or so, and decant the gas off of the mixture. (The water-gas interface will be very obvious.) 100% of the alcohol will find a home perfectly mixed in with the water. KZbin University has videos on this. HTH

Could also try a mixture of wintergreen oil and isopropyl alcohol. I used that for my carb boots on my 84 Honda Shadow a few months back because they were rock solid, and they are still very soft and pliable. Not sure if it would work in this case but worth a shot if it will last longer.

[@WeemanThe1]

@@VintageEngineRepairs It definitely is more expensive. If I remember right the small bottle i got was around $15 U.S. it is reusable but if it is an old machine that you cant find new rubber for, that may be worth it though. Otherwise like you stated, just replace it.

[@jefferyboring4410]

As a old bike tech. Hard boots I did a few things sometimes is dremel the inner lip edge. to help push the carb in. Add some bearing grease to slide in. I’d heat em up with a propane torch. Did that most often. Or sometimes I’d place all the rubbers in a pot of boiling water and install them quickly one at a time. They’d be super soft but hot. For over 20 yrs this was my go too methods.

[@44hawk28]

There is a product called 303 protectant, if you have the time to spray it on or soak it in this product, anything like a rubber diaphragm, the EPDM or rubber Serpentine belts, seals and the like even before you ever use it when they are already supple or if you need to rejuvenate it. It works great I've seen it used on tires a couple of times a year, even on the tread if you have the time to get up and and turn them around and spray it and and on the tread, I've seen tires tested where they've lasted three times longer than their normal wear. Older cars with the oil base High solids paint, when that paint gets oxidized and dull, I have taken rags and tested a small portion to make sure it doesn't damage the paint. By just barely dampening a cloth and then rubbing the paint down and got the paint to look like brand new by using brake fluid do not, do not, do not do that with water-based paint it will destroy the clear coat and the non clear coat paint does not farewell. Put an old 1970s Buick that is in good shape but has oxidized paint, responds wonderfully.

Hey, I don’t have a set time in mind, my videos are all different lengths, many of my more recent are 3-4 minutes as I have improved.

[@flitsies]

Or maybe it would last longer if you washed it off with brake cleaner to remove all residue of the brake fluid.

[@VintageEngineRepairs]

I think you’d just strip it of the oils you just impregnated in it to soften it in the first place.

[@flitsies]

@@VintageEngineRepairs It's just a thought but it might be worth a try, or perhaps clean it off with a washing up liquid detergent, something good enough to wash it off but not to strong to leave residue. Brake cleaner leaves no residual matter behind so it should be clean, if your diaphragms only last roughly 7 days perhaps take one that has come to it's end and try it over again but using the cleaner as you no longer have any use for it you would be able to see if it remained pliable and if it made any difference. What you got to lose, always worth trying if it costs nothing, assuming you got brake cleaner that is.

I buy the new ones that will never go bad because they are made out of a very small steel spring no rubber

[@VintageEngineRepairs]

Nice! I have seen them but not tried them. They’re by walbro, correct?

[@BillEyles]

Yes they are I run a small engine repair shop in Cincinnati and will only use them for repairs never had a come back with them

[@staind288]

​@@BillEyles I'm in Ohio too.

[@tomrogers9467]

If you’re soaking it for a week, probably not necessary to write the month and year on BOTH dates! Redundant redundancy.

[@VintageEngineRepairs]

Thanks for watching

[@hmdwn]

It may soften the rubber however usually the old used diaphragm is also distorted... the brake fluid won't take that out.

[@VintageEngineRepairs]

I have not found that to be the case, but never say never.

Thanks for watching.

[@nozzledrich]

great tip to know

[@VintageEngineRepairs]

Good to hear you enjoyed the video!

[@DonnyHooterHoot]

Sure they'll stay soft for a short while after this, but never very long!

[@VintageEngineRepairs]

Na - a couple weeks or so, but that’s quite a long time, long enough to get the replacement delivered, long enough to get your years supply of fire wood and long enough to diagnose running issues :)

[@DonnyHooterHoot]

@@VintageEngineRepairs Compared to YEARS for the life of a NEW part a couple of weeks is not You lose! Whee!

[@vittoriosilva1454]

The biggest problem is a vacuum leak at the rivet ....

[@VintageEngineRepairs]

Very interesting, I have never once found that! I’ll keep that in mind :)

[@vittoriosilva1454]

@@VintageEngineRepairs it's a fuel pressure vs vacuum thing , it'll die on decel , coming off full throttle ....

[@jonriley5695]

Break fluid will destroy it, and I would worry about contamination of other parts from the brake fluid.

[@VintageEngineRepairs]

Na it doesn’t

What's with the winter hat in the middle of June?

[@VintageEngineRepairs]

It’s cold! I’m in the southern hemisphere

[@speed8701]

Put it on a shelf and show me how it looks in one year.

[@VintageEngineRepairs]

You can test that if you like lol

[@BillEyles]

Why would waste your time I run small engine and mower shop and I buy them buy the pack of 100 for 12 bucks and can get them within 2 days

[@VintageEngineRepairs]

This isn’t intended for a commercial shop.

[@claytonchristophersen1633]

I have replaced toooooo many to remember that last diaphragm you say is new is used .! Fake .

[@VintageEngineRepairs]

I’m afraid you’re wrong, I took the new comparison diaphragm out of a box of 20 new diaphragms that I buy in bulk.

[@jamiebuckley1769]

i wonder if you could put in the microwave for 30 to 40 seconds and this might speed up the process?

[@VintageEngineRepairs]

I’m not too sure! If you decide to give it a go let me know the results :)

[@quinton3997]

Does this work when you get to old 😂

[@VintageEngineRepairs]

Sadly not 🤣😂

[@leehotspur9679]

Cheap enough to ditch for peace of mind

[@VintageEngineRepairs]

Only if you can get spares. This is useful for when you can’t

[@leehotspur9679]

Could you not use plastic shim material to fabricate a new one@@VintageEngineRepairs

[@VintageEngineRepairs]

Fab a new diaphragm? Na
