I suspect that the buildup you had was the result of prior exposure to ethanol gas. I had to scrap a gas tank from a CJ2A Jeep because the buildup was so bad.
I also run non-ethanol gas in my small engines. I run the N's on it too, because that is what I have the farm tank filled with. It costs more, but it is worth it in time and money saved.
Most needles I have seen are stainless steel (some with rubber tips), and the seats were brass. I have a 2N that is still using a needle & seat from the 1960's. It doesn't leak, and never has.
