yes the Cline does use Walbro parts (spring, seesaw and pin, float valve) and diaphragm and back plate,

I did cut a Walbro up, then cleaned it up on my lathe in the 4 Jaw Head stock, it was hard to keep in the jaws (off set) because one part on the Carb's body was only about 1MM thick, so that 1 jaw kept pushing the Carb out, plus I had to put wood behind the Carb's body to hold the body out and straight in the jaws,, in the end the cut came out really good, but the cut also opened a fuel port that would need to be welded close, so I just gave up on it, maybe if I get a newer carb I will try again, but then again I could just make a new manifold and put a Walbro on my engine
