ETW1 set up

[PareosWC]

Guys, I'm looking for the thread that discussed that with a ETW1 rebuild, you need to set the float height differently depending on whether you had an original all metal needle valve or viton tipped needle valve?

I used a quality rebuild kit, but it has the all metal needle. I plan on running as is, but I remember that there was quite a bit of discussion on ensuring you replace it with a viton tipped one....
