Title: LATEST INNOVATION IN DIAPHRAGM CARBURETORS
Post by: Cut4fun . on December 05, 2017, 12:59:45 am
Walbro’s revolutionary new Spiral metering diaphragm is unaffected by ethanol and provides consistent fuel delivery, engine performance and exhaust emissions throughout the life of hand-held products.

neat idea but total cost for the average consumer to retrofit one saw/trimmer is close to $30.....$20 for the diaphragm and $9.32 for the new mandatory gauge.

I think that is awesome and would gladly spend the money so that I do not have rebuild any of my carbs again.    Just think any one of my saws that has been sitting on a shelf for 2 or 3 years would just fire right up with no carb problems.

In the video he said the new gauge is included in the spiral diaphragm kit so that makes it 20 bucks total. Reasonable if you have a carb in rebuild-able condition.

Wonder how soon the Asian fakes will hit the market?

Wonder if that is all the retrofits they are planning? Not very many numbers in the drop down.

That is not a very good selection for us saw users. Maybe more will come in the future.

I did email walbro and asked them about the spiral diaphragms for WJ series carbs.  Below is there response.

" At this moment we do not have a Spiral Diaphragm Kit for the WJ-76 but we do have our engineering actively working on more of these carburetors.

I expect to have a concrete answer or direction for you within the next couple of months."
