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.

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.

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.

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.

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.

​@@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. KZread University has videos on this. HTH

Brilliant , very useful tutorial. Do you think a long soak (several months) could prevent it from rehardening? Thanks and all the best from New Rochelle N.Y.

@@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.

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

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 :)

Bad idea ! Brake fluid on a mineral based rubber will continue to soften the rubber and eventually dissolve or crumble, I have tested this countless times and it is a bad idea. Mineral based oil on a brake fluid rubber is much worse !
