Hello guys, I hope you are okay. I came across this jet on a Px 900 carburator. Taking into account the pic attached, could you please provide further info about the engraved numbers? We all know that those lanterns were graded 100, but I see a 101 and 28 below... is it a standard jet or not? Thanks a bundle!
This is a Radius jet for a model 101. The 101 was more or less a clone of the Px 900 and most parts are interchangeable. Standard numbering for Radius parts is that the first number is the model that the part first appeared on and the second number is the par type. Here you can see that the model is a 101 and the part type is 28, which is what Radius used for jets.
