Maybe A step forward for Carbs......

Put this in the Chainsaw section as I thought most folks would see.
Worth a look if you are unfamiliar with this.

That's very interesting. But the diaphragm isn't the only carb part that ethanol and more importantly the water content it creates negatively effects. Step in the right direction though. But I'll still buy e-free fuel for all my stuff.

Husqvarna seem to see this as a good idea .....2018 ipl

A pump side diaphragm handles ethanol quite a bit better than the much more sensitive metering side.

I agree wholeheartedly the material is the problem not the ethanol .

Some epa peeps say (wtf they like), and everyone else has to jump and change . Not that is easy for us consumers to say much.

I say ethanol free fuel, but there again I live in the uk and aspen fuel is taxed like road fuel. Who uses aspen on 5he road !.Nobody listens, only the tax has the real say.

Nah, really it’s just a lack of understanding between those party’s involved.

I have not seen or heard of it being used in saws yet. Cool concept for sure

The pump side diaphragm I'm referring to is the same material as the metering side. Ethanol makes fuel lines swell up or soften. It will also soften up crank seals, fuel tank vent lines, and intake boots. Black bubblegum.

That's along the lines of what I was getting at Jim. Good to see the metering diaphragm redesigned to be suitable but that's not the only component that reacts poorly.
