curious….  but why would the needle & seat affect the carb  since  all it does is allow or block the inflow of fuel in the carb bowl.   rich or lean  is governed  by  needles or orifices  not the inlet needle point.

it is early….am  I missing something  ???

Ha Ha! Nope, you’re not missing anything. I’m overthinking it, again!

LOL

Yep – Makes complete sense.

Also – I stand corrected on a point or two. I’m out in the garage right now. I measured as best I could the seat diameter for the OEM one. A 1/16″ drill bit shaft will “Just” not fit into the hole on the original seat. The newer seats in the 439071 kit will allow the 1/16″ shaft to go into the hole.  Where I am 10000% wrong and need to correct myself is the Sierra 18-7094 needle and seat appears to be an exact duplicate. The 1/16″ shaft will not go into the hole. And yes, it shows on the package that it replaces 396522, so that jives as well.

Thanks all – Worried about nothing, again!
