371xp carb question

[mifirewoodguy]

I was given a 371xp along with a box of parts, I found a Zama carb that looks like it goes to it in the box, IPL's show a Walbro carb. Does anyone know if the early 317xp's came with a Zama carb?

My manuel says the zama is fitted to the 365, where as the 362 and the 371 both have the walbro hd6, the zama on the 365 model no. is c3m-el2a
Don't know why they are different, hopefully someone else can shed some light on it.
