Carb Throttle Adapter for Echo RY25AXB Blower by RebelTaz
All of the aftermarket carburetors on Amazon that claim to fit the Echo RY25AXB, don't To be more specific, the carburetor itself fits and works great. The throttle cable won't attach to it, though. The cable on the blower has a z-bend where the butterfly lever on the carburetor is designed for barrel connector. Usually you can just unclip the connector, pull it out and stick the z-bend in the hole. That doesn't work in this case, though, because the hole it too big and the z-bend just pops right out. This is a super simple adapter that sits in the hole on the lever that you can attach the z-bend to. It works great and is probably best printed on a resin printer. Even better is a resin printer with a magnetic flex plate, so you can print the adapter flat on the plate, as I did here.
NOTE Due to either a Thingiverse bug or (more likely) shadowbanning, my models no longer show up under the [Newest] listings. If you want to see more of my models, please be sure to 'follow' me. If you print this, it would really help if you'd post a 'make' so that others could find this model.
