Questions: Why is this recommended with a dry filter element instead of the factory oil bath filter? Also is this recommended over the slightly cheaper show quality YF you sell? Last, where is this manufactured?
Question By: Matthew Addison on May 12 2020 3:30 PM
You could use either. But a dry functions a bit better than the original oil bath. I'll check on origin.

Questions: Is this designed to be a direct replacement for the Carter YF-938 or will there be modifications to fuel line, choke and throttle cables required? I am interested in giving this one a try but would like to not have to make any modifications in case I later decide to go back to my Carter.
