What carb will fit my 170?

[nola mike]

I think i have some carb issues with my 3.7L 170. I'd like to try my hand at rebuilding one. Since the issues are (so far) minor, I want to get a spare that I can take my time with. Looking at the part #'s, it seems like all the carbs for the 470's are different. Are really none of them interchangeable? If not, what are the differences? Will a carb from any other engine work?

You need a 2 barrel Mercarb. Hear is a Pic and the explanation of the part Number.

This what the manual says the proper part numbers should be.
